-
-## [2025-04-17] Added Content Source Selection for Markdown Generation
-
-**Feature:** Configurable content source for markdown generation
-
-**Changes Made:**
-1. Added `content_source: str = "cleaned_html"` parameter to `MarkdownGenerationStrategy` class
-2. Updated `DefaultMarkdownGenerator` to accept and pass the content source parameter
-3. Renamed the `cleaned_html` parameter to `input_html` in the `generate_markdown` method
-4. Modified `AsyncWebCrawler.aprocess_html` to select the appropriate HTML source based on the generator's config
-5. Added `preprocess_html_for_schema` import in `async_webcrawler.py`
-
-**Implementation Details:**
-- Added a new `content_source` parameter to specify which HTML input to use for markdown generation
-- Options include: "cleaned_html" (default), "raw_html", and "fit_html"
-- Used a dictionary dispatch pattern in `aprocess_html` to select the appropriate HTML source
-- Added proper error handling with fallback to cleaned_html if content source selection fails
-- Ensured backward compatibility by defaulting to "cleaned_html" option
-
-**Files Modified:**
-- `crawl4ai/markdown_generation_strategy.py`: Added content_source parameter and updated the method signature
-- `crawl4ai/async_webcrawler.py`: Added HTML source selection logic and updated imports
-
-**Examples:**
-- Created `docs/examples/content_source_example.py` demonstrating how to use the new parameter
-
-**Challenges:**
-- Maintaining backward compatibility while reorganizing the parameter flow
-- Ensuring proper error handling for all content source options
-- Making the change with minimal code modifications
-
-**Why This Feature:**
-The content source selection feature allows users to choose which HTML content to use as input for markdown generation:
-1. "cleaned_html" - Uses the post-processed HTML after scraping strategy (original behavior)
-2. "raw_html" - Uses the original raw HTML directly from the web page
-3. "fit_html" - Uses the preprocessed HTML optimized for schema extraction
-
-This feature provides greater flexibility in how users generate markdown, enabling them to:
-- Capture more detailed content from the original HTML when needed
-- Use schema-optimized HTML when working with structured data
-- Choose the approach that best suits their specific use case
-## [2025-04-17] Implemented High Volume Stress Testing Solution for SDK
-
-**Feature:** Comprehensive stress testing framework using `arun_many` and the dispatcher system to evaluate performance, concurrency handling, and identify potential issues under high-volume crawling scenarios.
-
-**Changes Made:**
-1.  Created a dedicated stress testing framework in the `benchmarking/` (or similar) directory.
-2.  Implemented local test site generation (`SiteGenerator`) with configurable heavy HTML pages.
-3.  Added basic memory usage tracking (`SimpleMemoryTracker`) using platform-specific commands (avoiding `psutil` dependency for this specific test).
-4.  Utilized `CrawlerMonitor` from `crawl4ai` for rich terminal UI and real-time monitoring of test progress and dispatcher activity.
-5.  Implemented detailed result summary saving (JSON) and memory sample logging (CSV).
-6.  Developed `run_benchmark.py` to orchestrate tests with predefined configurations.
-7.  Created `run_all.sh` as a simple wrapper for `run_benchmark.py`.
-
-**Implementation Details:**
--   Generates a local test site with configurable pages containing heavy text and image content.
--   Uses Python's built-in `http.server` for local serving, minimizing network variance.
--   Leverages `crawl4ai`'s `arun_many` method for processing URLs.
--   Utilizes `MemoryAdaptiveDispatcher` to manage concurrency via the `max_sessions` parameter (note: memory adaptation features require `psutil`, not used by `SimpleMemoryTracker`).
--   Tracks memory usage via `SimpleMemoryTracker`, recording samples throughout test execution to a CSV file.
--   Uses `CrawlerMonitor` (which uses the `rich` library) for clear terminal visualization and progress reporting directly from the dispatcher.
--   Stores detailed final metrics in a JSON summary file.
-
-**Files Created/Updated:**
--   `stress_test_sdk.py`: Main stress testing implementation using `arun_many`.
--   `benchmark_report.py`: (Assumed) Report generator for comparing test results.
--   `run_benchmark.py`: Test runner script with predefined configurations.
--   `run_all.sh`: Simple bash script wrapper for `run_benchmark.py`.
--   `USAGE.md`: Comprehensive documentation on usage and interpretation (updated).
-
-**Testing Approach:**
--   Creates a controlled, reproducible test environment with a local HTTP server.
--   Processes URLs using `arun_many`, allowing the dispatcher to manage concurrency up to `max_sessions`.
--   Optionally logs per-batch summaries (when not in streaming mode) after processing chunks.
--   Supports different test sizes via `run_benchmark.py` configurations.
--   Records memory samples via platform commands for basic trend analysis.
--   Includes cleanup functionality for the test environment.
-
-**Challenges:**
--   Ensuring proper cleanup of HTTP server processes.
--   Getting reliable memory tracking across platforms without adding heavy dependencies (`psutil`) to this specific test script.
--   Designing `run_benchmark.py` to correctly pass arguments to `stress_test_sdk.py`.
-
-**Why This Feature:**
-The high volume stress testing solution addresses critical needs for ensuring Crawl4AI's `arun_many` reliability:
-1.  Provides a reproducible way to evaluate performance under concurrent load.
-2.  Allows testing the dispatcher's concurrency control (`max_session_permit`) and queue management.
-3.  Enables performance tuning by observing throughput (`URLs/sec`) under different `max_sessions` settings.
-4.  Creates a controlled environment for testing `arun_many` behavior.
-5.  Supports continuous integration by providing deterministic test conditions for `arun_many`.
-
-**Design Decisions:**
--   Chose local site generation for reproducibility and isolation from network issues.
--   Utilized the built-in `CrawlerMonitor` for real-time feedback, leveraging its `rich` integration.
--   Implemented optional per-batch logging in `stress_test_sdk.py` (when not streaming) to provide chunk-level summaries alongside the continuous monitor.
--   Adopted `arun_many` with a `MemoryAdaptiveDispatcher` as the core mechanism for parallel execution, reflecting the intended SDK usage.
--   Created `run_benchmark.py` to simplify running standard test configurations.
--   Used `SimpleMemoryTracker` to provide basic memory insights without requiring `psutil` for this particular test runner.
-
-**Future Enhancements to Consider:**
--   Create a separate test variant that *does* use `psutil` to specifically stress the memory-adaptive features of the dispatcher.
--   Add support for generated JavaScript content.
--   Add support for Docker-based testing with explicit memory limits.
--   Enhance `benchmark_report.py` to provide more sophisticated analysis of performance and memory trends from the generated JSON/CSV files.

-## [2025-04-17] Refined Stress Testing System Parameters and Execution
-
-**Changes Made:**
-1.  Corrected `run_benchmark.py` and `stress_test_sdk.py` to use `--max-sessions` instead of the incorrect `--workers` parameter, accurately reflecting dispatcher configuration.
-2.  Updated `run_benchmark.py` argument handling to correctly pass all relevant custom parameters (including `--stream`, `--monitor-mode`, etc.) to `stress_test_sdk.py`.
-3.  (Assuming changes in `benchmark_report.py`) Applied dark theme to benchmark reports for better readability.
-4.  (Assuming changes in `benchmark_report.py`) Improved visualization code to eliminate matplotlib warnings.
-5.  Updated `run_benchmark.py` to provide clickable `file://` links to generated reports in the terminal output.
-6.  Updated `USAGE.md` with comprehensive parameter descriptions reflecting the final script arguments.
-7.  Updated `run_all.sh` wrapper to correctly invoke `run_benchmark.py` with flexible arguments.
-
-**Details of Changes:**
-
-1.  **Parameter Correction (`--max-sessions`)**:
-    *   Identified the fundamental misunderstanding where `--workers` was used incorrectly.
-    *   Refactored `stress_test_sdk.py` to accept `--max-sessions` and configure the `MemoryAdaptiveDispatcher`'s `max_session_permit` accordingly.
-    *   Updated `run_benchmark.py` argument parsing and command construction to use `--max-sessions`.
-    *   Updated `TEST_CONFIGS` in `run_benchmark.py` to use `max_sessions`.
-
-2.  **Argument Handling (`run_benchmark.py`)**:
-    *   Improved logic to collect all command-line arguments provided to `run_benchmark.py`.
-    *   Ensured all relevant arguments (like `--stream`, `--monitor-mode`, `--port`, `--use-rate-limiter`, etc.) are correctly forwarded when calling `stress_test_sdk.py` as a subprocess.
-
-3.  **Dark Theme & Visualization Fixes (Assumed in `benchmark_report.py`)**:
-    *   (Describes changes assumed to be made in the separate reporting script).
-
-4.  **Clickable Links (`run_benchmark.py`)**:
-    *   Added logic to find the latest HTML report and PNG chart in the `benchmark_reports` directory after `benchmark_report.py` runs.
-    *   Used `pathlib` to generate correct `file://` URLs for terminal output.
-
-5.  **Documentation Improvements (`USAGE.md`)**:
-    *   Rewrote sections to explain `arun_many`, dispatchers, and `--max-sessions`.
-    *   Updated parameter tables for all scripts (`stress_test_sdk.py`, `run_benchmark.py`).
-    *   Clarified the difference between batch and streaming modes and their effect on logging.
-    *   Updated examples to use correct arguments.
-
-**Files Modified:**
--   `stress_test_sdk.py`: Changed `--workers` to `--max-sessions`, added new arguments, used `arun_many`.
--   `run_benchmark.py`: Changed argument handling, updated configs, calls `stress_test_sdk.py`.
--   `run_all.sh`: Updated to call `run_benchmark.py` correctly.
--   `USAGE.md`: Updated documentation extensively.
--   `benchmark_report.py`: (Assumed modifications for dark theme and viz fixes).
-
-**Testing:**
--   Verified that `--max-sessions` correctly limits concurrency via the `CrawlerMonitor` output.
--   Confirmed that custom arguments passed to `run_benchmark.py` are forwarded to `stress_test_sdk.py`.
--   Validated clickable links work in supporting terminals.
--   Ensured documentation matches the final script parameters and behavior.
-
-**Why These Changes:**
-These refinements correct the fundamental approach of the stress test to align with `crawl4ai`'s actual architecture and intended usage:
-1.  Ensures the test evaluates the correct components (`arun_many`, `MemoryAdaptiveDispatcher`).
-2.  Makes test configurations more accurate and flexible.
-3.  Improves the usability of the testing framework through better argument handling and documentation.
-
-
-**Future Enhancements to Consider:**
-- Add support for generated JavaScript content to test JS rendering performance
-- Implement more sophisticated memory analysis like generational garbage collection tracking
-- Add support for Docker-based testing with memory limits to force OOM conditions
-- Create visualization tools for analyzing memory usage patterns across test runs
-- Add benchmark comparisons between different crawler versions or configurations

-- Add additional visualization options for different types of analysis
-- Implement theme toggle to support both light and dark preferences
-- Add export options for embedding reports in other documentation
-- Create dedicated CI/CD integration templates for automated testing
-
-## [2025-04-09] Added MHTML Capture Feature
-
-**Feature:** MHTML snapshot capture of crawled pages
-
-**Changes Made:**
-1. Added `capture_mhtml: bool = False` parameter to `CrawlerRunConfig` class
-2. Added `mhtml: Optional[str] = None` field to `CrawlResult` model
-3. Added `mhtml_data: Optional[str] = None` field to `AsyncCrawlResponse` class
-4. Implemented `capture_mhtml()` method in `AsyncPlaywrightCrawlerStrategy` class to capture MHTML via CDP
-5. Modified the crawler to capture MHTML when enabled and pass it to the result
-
-**Implementation Details:**
-- MHTML capture uses Chrome DevTools Protocol (CDP) via Playwright's CDP session API
-- The implementation waits for page to fully load before capturing MHTML content
-- Enhanced waiting for JavaScript content with requestAnimationFrame for better JS content capture
-- We ensure all browser resources are properly cleaned up after capture
-
-**Files Modified:**
-- `crawl4ai/models.py`: Added the mhtml field to CrawlResult
-- `crawl4ai/async_configs.py`: Added capture_mhtml parameter to CrawlerRunConfig
-- `crawl4ai/async_crawler_strategy.py`: Implemented MHTML capture logic
-- `crawl4ai/async_webcrawler.py`: Added mapping from AsyncCrawlResponse.mhtml_data to CrawlResult.mhtml
-
-**Testing:**
-- Created comprehensive tests in `tests/20241401/test_mhtml.py` covering:
-  - Capturing MHTML when enabled
-  - Ensuring mhtml is None when disabled explicitly
-  - Ensuring mhtml is None by default
-  - Capturing MHTML on JavaScript-enabled pages
-
-**Challenges:**
-- Had to improve page loading detection to ensure JavaScript content was fully rendered
-- Tests needed to be run independently due to Playwright browser instance management
-- Modified test expected content to match actual MHTML output
-
-**Why This Feature:**
-The MHTML capture feature allows users to capture complete web pages including all resources (CSS, images, etc.) in a single file. This is valuable for:
-1. Offline viewing of captured pages
-2. Creating permanent snapshots of web content for archival
-3. Ensuring consistent content for later analysis, even if the original site changes
-
-**Future Enhancements to Consider:**
-- Add option to save MHTML to file
-- Support for filtering what resources get included in MHTML
-- Add support for specifying MHTML capture options
-
-## [2025-04-10] Added Network Request and Console Message Capturing
-
-**Feature:** Comprehensive capturing of network requests/responses and browser console messages during crawling
-
-**Changes Made:**
-1. Added `capture_network_requests: bool = False` and `capture_console_messages: bool = False` parameters to `CrawlerRunConfig` class
-2. Added `network_requests: Optional[List[Dict[str, Any]]] = None` and `console_messages: Optional[List[Dict[str, Any]]] = None` fields to both `AsyncCrawlResponse` and `CrawlResult` models
-3. Implemented event listeners in `AsyncPlaywrightCrawlerStrategy._crawl_web()` to capture browser network events and console messages
-4. Added proper event listener cleanup in the finally block to prevent resource leaks
-5. Modified the crawler flow to pass captured data from AsyncCrawlResponse to CrawlResult
-
-**Implementation Details:**
-- Network capture uses Playwright event listeners (`request`, `response`, and `requestfailed`) to record all network activity
-- Console capture uses Playwright event listeners (`console` and `pageerror`) to record console messages and errors
-- Each network event includes metadata like URL, headers, status, and timing information
-- Each console message includes type, text content, and source location when available
-- All captured events include timestamps for chronological analysis
-- Error handling ensures even failed capture attempts won't crash the main crawling process
-
-**Files Modified:**
-- `crawl4ai/models.py`: Added new fields to AsyncCrawlResponse and CrawlResult
-- `crawl4ai/async_configs.py`: Added new configuration parameters to CrawlerRunConfig
-- `crawl4ai/async_crawler_strategy.py`: Implemented capture logic using event listeners
-- `crawl4ai/async_webcrawler.py`: Added data transfer from AsyncCrawlResponse to CrawlResult
-
-**Documentation:**
-- Created detailed documentation in `docs/md_v2/advanced/network-console-capture.md`
-- Added feature to site navigation in `mkdocs.yml`
-- Updated CrawlResult documentation in `docs/md_v2/api/crawl-result.md`
-- Created comprehensive example in `docs/examples/network_console_capture_example.py`
-
-**Testing:**
-- Created `tests/general/test_network_console_capture.py` with tests for:
-  - Verifying capture is disabled by default
-  - Testing network request capturing
-  - Testing console message capturing
-  - Ensuring both capture types can be enabled simultaneously
-  - Checking correct content is captured in expected formats
-
-**Challenges:**
-- Initial implementation had synchronous/asynchronous mismatches in event handlers
-- Needed to fix type of property access vs. method calls in handlers
-- Required careful cleanup of event listeners to prevent memory leaks
-
-**Why This Feature:**
-The network and console capture feature provides deep visibility into web page activity, enabling:
-1. Debugging complex web applications by seeing all network requests and errors
-2. Security analysis to detect unexpected third-party requests and data flows
-3. Performance profiling to identify slow-loading resources
-4. API discovery in single-page applications
-5. Comprehensive analysis of web application behavior
-
-**Future Enhancements to Consider:**
-- Option to filter captured events by type, domain, or content
-- Support for capturing response bodies (with size limits)
-- Aggregate statistics calculation for performance metrics
-- Integration with visualization tools for network waterfall analysis
-- Exporting captures in HAR format for use with external tools

-# Crawl4AI Prospect‑Wizard – step‑by‑step guide
-
-A three‑stage demo that goes from **LinkedIn scraping** ➜ **LLM reasoning** ➜ **graph visualisation**.
-
-```
-prospect‑wizard/
-├─ c4ai_discover.py         # Stage 1 – scrape companies + people
-├─ c4ai_insights.py         # Stage 2 – embeddings, org‑charts, scores
-├─ graph_view_template.html # Stage 3 – graph viewer (static HTML)
-└─ data/                    # output lands here (*.jsonl / *.json)
-```
-
----
-
-## 1  Install & boot a LinkedIn profile (one‑time)
-
-### 1.1  Install dependencies
-```bash
-pip install crawl4ai litellm sentence-transformers pandas rich
-```
-
-### 1.2  Create / warm a LinkedIn browser profile
-```bash
-crwl profiles
-```
-1. The interactive shell shows **New profile** – hit **enter**.
-2. Choose a name, e.g. `profile_linkedin_uc`.
-3. A Chromium window opens – log in to LinkedIn, solve whatever CAPTCHA, then close.
-
-> Remember the **profile name**. All future runs take `--profile-name <your_name>`.
-
----
-
-## 2  Discovery – scrape companies & people
-
-```bash
-python c4ai_discover.py full \
-  --query "health insurance management" \
-  --geo 102713980 \               # Malaysia geoUrn
-  --title-filters "" \            # or "Product,Engineering"
-  --max-companies 10 \            # default set small for workshops
-  --max-people 20 \               # \^ same
-  --profile-name profile_linkedin_uc \
-  --outdir ./data \
-  --concurrency 2 \
-  --log-level debug
-```
-**Outputs** in `./data/`:
-* `companies.jsonl` – one JSON per company
-* `people.jsonl` – one JSON per employee
-
-🛠️  **Dry‑run:** `C4AI_DEMO_DEBUG=1 python c4ai_discover.py full --query coffee` uses bundled HTML snippets, no network.
-
-### Handy geoUrn cheatsheet
-| Location | geoUrn |
-|----------|--------|
-| Singapore | **103644278** |
-| Malaysia | **102713980** |
-| United States | **103644922** |
-| United Kingdom | **102221843** |
-| Australia | **101452733** |
-_See more: <https://www.linkedin.com/search/results/companies/?geoUrn=XXX> – the number after `geoUrn=` is what you need._
-
----
-
-## 3  Insights – embeddings, org‑charts, decision makers
-
-```bash
-python c4ai_insights.py \
-  --in ./data \
-  --out ./data \
-  --embed-model all-MiniLM-L6-v2 \
-  --llm-provider gemini/gemini-2.0-flash \
-  --llm-api-key "" \
-  --top-k 10 \
-  --max-llm-tokens 8024 \
-  --llm-temperature 1.0 \
-  --workers 4
-```
-Emits next to the Stage‑1 files:
-* `company_graph.json` – inter‑company similarity graph
-* `org_chart_<handle>.json` – one per company
-* `decision_makers.csv` – hand‑picked ‘who to pitch’ list
-
-Flags reference (straight from `build_arg_parser()`):
-| Flag | Default | Purpose |
-|------|---------|---------|
-| `--in` | `.` | Stage‑1 output dir |
-| `--out` | `.` | Destination dir |
-| `--embed_model` | `all-MiniLM-L6-v2` | Sentence‑Transformer model |
-| `--top_k` | `10` | Neighbours per company in graph |
-| `--openai_model` | `gpt-4.1` | LLM for scoring decision makers |
-| `--max_llm_tokens` | `8024` | Token budget per LLM call |
-| `--llm_temperature` | `1.0` | Creativity knob |
-| `--stub` | off | Skip OpenAI and fabricate tiny charts |
-| `--workers` | `4` | Parallel LLM workers |
-
----
-
-## 4  Visualise – interactive graph
-
-After Stage 2 completes, simply open the HTML viewer from the project root:
-```bash
-open graph_view_template.html   # or Live Server / Python -http
-```
-The page fetches `data/company_graph.json` and the `org_chart_*.json` files automatically; keep the `data/` folder beside the HTML file.
-
-* Left pane → list of companies (clans).
-* Click a node to load its org‑chart on the right.
-* Chat drawer lets you ask follow‑up questions; context is pulled from `people.jsonl`.
-
----
-
-## 5  Common snags
-
-| Symptom | Fix |
-|---------|-----|
-| Infinite CAPTCHA | Use a residential proxy: `--proxy http://user:pass@ip:port` |
-| 429 Too Many Requests | Lower `--concurrency`, rotate profile, add delay |
-| Blank graph | Check JSON paths, clear `localStorage` in browser |
-
----
-
-### TL;DR
-`crwl profiles` → `c4ai_discover.py` → `c4ai_insights.py` → open `graph_view_template.html`.  
-Live long and `import crawl4ai`.

-c4ai-discover — Stage‑1 Discovery CLI
-
-Scrapes LinkedIn company search + their people pages and dumps two newline‑delimited
-JSON files: companies.jsonl and people.jsonl.
-
-Key design rules
-----------------
-* No BeautifulSoup — Crawl4AI only for network + HTML fetch.
-* JsonCssExtractionStrategy for structured scraping; schema auto‑generated once
-  from sample HTML provided by user and then cached under ./schemas/.
-* Defaults are embedded so the file runs inside VS Code debugger without CLI args.
-* If executed as a console script (argv > 1), CLI flags win.
-* Lightweight deps: argparse + Crawl4AI stack.

-### browser_manager.py
-
-| Function | What it does |
-|---|---|
-| `ManagedBrowser.build_browser_flags` | Returns baseline Chromium CLI flags, disables GPU and sandbox, plugs locale, timezone, stealth tweaks, and any extras from `BrowserConfig`. |
-| `ManagedBrowser.__init__` | Stores config and logger, creates temp dir, preps internal state. |
-| `ManagedBrowser.start` | Spawns or connects to the Chromium process, returns its CDP endpoint plus the `subprocess.Popen` handle. |
-| `ManagedBrowser._initial_startup_check` | Pings the CDP endpoint once to be sure the browser is alive, raises if not. |
-| `ManagedBrowser._monitor_browser_process` | Async-loops on the subprocess, logs exits or crashes, restarts if policy allows. |
-| `ManagedBrowser._get_browser_path_WIP` | Old helper that maps OS + browser type to an executable path. |
-| `ManagedBrowser._get_browser_path` | Current helper, checks env vars, Playwright cache, and OS defaults for the real executable. |
-| `ManagedBrowser._get_browser_args` | Builds the final CLI arg list by merging user flags, stealth flags, and defaults. |
-| `ManagedBrowser.cleanup` | Terminates the browser, stops monitors, deletes the temp dir. |
-| `ManagedBrowser.create_profile` | Opens a visible browser so a human can log in, then zips the resulting user-data-dir to `~/.crawl4ai/profiles/<name>`. |
-| `ManagedBrowser.list_profiles` | Thin wrapper, now forwarded to `BrowserProfiler.list_profiles()`. |
-| `ManagedBrowser.delete_profile` | Thin wrapper, now forwarded to `BrowserProfiler.delete_profile()`. |
-| `BrowserManager.__init__` | Holds the global Playwright instance, browser handle, config signature cache, session map, and logger. |
-| `BrowserManager.start` | Boots the underlying `ManagedBrowser`, then spins up the default Playwright browser context with stealth patches. |
-| `BrowserManager._build_browser_args` | Translates `CrawlerRunConfig` (proxy, UA, timezone, headless flag, etc.) into Playwright `launch_args`. |
-| `BrowserManager.setup_context` | Applies locale, geolocation, permissions, cookies, and UA overrides on a fresh context. |
-| `BrowserManager.create_browser_context` | Internal helper that actually calls `browser.new_context(**options)` after running `setup_context`. |
-| `BrowserManager._make_config_signature` | Hashes the non-ephemeral parts of `CrawlerRunConfig` so contexts can be reused safely. |
-| `BrowserManager.get_page` | Returns a ready `Page` for a given session id, reusing an existing one or creating a new context/page, injects helper scripts, updates `last_used`. |
-| `BrowserManager.kill_session` | Force-closes a context/page for a session and removes it from the session map. |
-| `BrowserManager._cleanup_expired_sessions` | Periodic sweep that drops sessions idle longer than `ttl_seconds`. |
-| `BrowserManager.close` | Gracefully shuts down all contexts, the browser, Playwright, and background tasks. |

-### browser_profiler.py
-
-| Function | What it does |
-|---|---|
-| `BrowserProfiler.__init__` | Sets up profile folder paths, async logger, and signal handlers. |
-| `BrowserProfiler.create_profile` | Launches a visible browser with a new user-data-dir for manual login, on exit compresses and stores it as a named profile. |
-| `BrowserProfiler.cleanup_handler` | General SIGTERM/SIGINT cleanup wrapper that kills child processes. |
-| `BrowserProfiler.sigint_handler` | Handles Ctrl-C during an interactive session, makes sure the browser shuts down cleanly. |
-| `BrowserProfiler.listen_for_quit_command` | Async REPL that exits when the user types `q`. |
-| `BrowserProfiler.list_profiles` | Enumerates `~/.crawl4ai/profiles`, prints profile name, browser type, size, and last modified. |
-| `BrowserProfiler.get_profile_path` | Returns the absolute path of a profile given its name, or `None` if missing. |
-| `BrowserProfiler.delete_profile` | Removes a profile folder or a direct path from disk, with optional confirmation prompt. |
-| `BrowserProfiler.interactive_manager` | Text UI loop for listing, creating, deleting, or launching profiles. |
-| `BrowserProfiler.launch_standalone_browser` | Starts a non-headless Chromium with remote debugging enabled and keeps it alive for manual tests. |
-| `BrowserProfiler.get_cdp_json` | Pulls `/json/version` from a CDP endpoint and returns the parsed JSON. |
-| `BrowserProfiler.launch_builtin_browser` | Spawns a headless Chromium in the background, saves `{wsEndpoint, pid, started_at}` to `~/.crawl4ai/builtin_browser.json`. |
-| `BrowserProfiler.get_builtin_browser_info` | Reads that JSON file, verifies the PID, and returns browser status info. |
-| `BrowserProfiler._is_browser_running` | Cross-platform helper that checks if a PID is still alive. |
-| `BrowserProfiler.kill_builtin_browser` | Terminates the background builtin browser and removes its status file. |
-| `BrowserProfiler.get_builtin_browser_status` | Returns `{running: bool, wsEndpoint, pid, started_at}` for quick health checks. |

-### `cli.py` command surface
-
-| Command | Inputs / flags | What it does |
-|---|---|---|
-| **profiles** | *(none)* | Opens the interactive profile manager, lets you list, create, delete saved browser profiles that live in `~/.crawl4ai/profiles`. |
-| **browser status** | – | Prints whether the always-on *builtin* browser is running, shows its CDP URL, PID, start time. |
-| **browser stop** | – | Kills the builtin browser and deletes its status file. |
-| **browser view** | `--url, -u` URL *(optional)* | Pops a visible window of the builtin browser, navigates to `URL` or `about:blank`. |
-| **config list** | – | Dumps every global setting, showing current value, default, and description. |
-| **config get** | `key` | Prints the value of a single setting, falls back to default if unset. |
-| **config set** | `key value` | Persists a new value in the global config (stored under `~/.crawl4ai/config.yml`). |
-| **examples** | – | Just spits out real-world CLI usage samples. |
-| **crawl** | `url` *(positional)*<br>`--browser-config,-B` path<br>`--crawler-config,-C` path<br>`--filter-config,-f` path<br>`--extraction-config,-e` path<br>`--json-extract,-j` [desc]\*<br>`--schema,-s` path<br>`--browser,-b` k=v list<br>`--crawler,-c` k=v list<br>`--output,-o` all,json,markdown,md,markdown-fit,md-fit *(default all)*<br>`--output-file,-O` path<br>`--bypass-cache,-b` *(flag, default true — note flag reuse)*<br>`--question,-q` str<br>`--verbose,-v` *(flag)*<br>`--profile,-p` profile-name | One-shot crawl + extraction. Builds `BrowserConfig` and `CrawlerRunConfig` from inline flags or separate YAML/JSON files, runs `AsyncWebCrawler.run()`, can route through a named saved profile and pipe the result to stdout or a file. |
-| **(default)** | Same flags as **crawl**, plus `--example` | Shortcut so you can type just `crwl https://site.com`. When first arg is not a known sub-command, it falls through to *crawl*. |
-
-\* `--json-extract/-j` with no value turns on LLM-based JSON extraction using an auto schema, supplying a string lets you prompt-engineer the field descriptions.
-
-> Quick mental model  
-> `profiles` = manage identities,  
-> `browser ...` = control long-running headless Chrome that all crawls can piggy-back on,  
-> `crawl` = do the actual work,  
-> `config` = tweak global defaults,  
-> everything else is sugar.
-
-### Quick-fire “profile” usage cheatsheet
-
-| Scenario | Command (copy-paste ready) | Notes |
-|---|---|---|
-| **Launch interactive Profile Manager UI** | `crwl profiles` | Opens TUI with options: 1 List, 2 Create, 3 Delete, 4 Use-to-crawl, 5 Exit. |
-| **Create a fresh profile** | `crwl profiles` → choose **2** → name it → browser opens → log in → press **q** in terminal | Saves to `~/.crawl4ai/profiles/<name>`. |
-| **List saved profiles** | `crwl profiles` → choose **1** | Shows name, browser type, size, last-modified. |
-| **Delete a profile** | `crwl profiles` → choose **3** → pick the profile index → confirm | Removes the folder. |
-| **Crawl with a profile (default alias)** | `crwl https://site.com/dashboard -p my-profile` | Keeps login cookies, sets `use_managed_browser=true` under the hood. |
-| **Crawl + verbose JSON output** | `crwl https://site.com -p my-profile -o json -v` | Any other `crawl` flags work the same. |
-| **Crawl with extra browser tweaks** | `crwl https://site.com -p my-profile -b "headless=true,viewport_width=1680"` | CLI overrides go on top of the profile. |
-| **Same but via explicit sub-command** | `crwl crawl https://site.com -p my-profile` | Identical to default alias. |
-| **Use profile from inside Profile Manager** | `crwl profiles` → choose **4** → pick profile → enter URL → follow prompts | Handy when demo-ing to non-CLI folks. |
-| **One-off crawl with a profile folder path (no name lookup)** | `crwl https://site.com -b "user_data_dir=$HOME/.crawl4ai/profiles/my-profile,use_managed_browser=true"` | Bypasses registry, useful for CI scripts. |
-| **Launch a dev browser on CDP port with the same identity** | `crwl cdp -d $HOME/.crawl4ai/profiles/my-profile -P 9223` | Lets Puppeteer/Playwright attach for debugging. |

-3 bite-sized demos that parallel the style of *quickstart_examples_set_1.py*:
-
-1.  **Default catalog** – scrape a page and pull out e-mails / phones / URLs, etc.
-2.  **Custom pattern**  – add your own regex at instantiation time.
-3.  **LLM-assisted schema** – ask the model to write a pattern, cache it, then
-    run extraction _without_ further LLM calls.

-Run the whole thing with::

-## 7. Locale, Timezone, and Geolocation Control
-
-In addition to using persistent profiles, Crawl4AI supports customizing your browser's locale, timezone, and geolocation settings. These features enhance your identity-based browsing experience by allowing you to control how websites perceive your location and regional settings.
-
-### Setting Locale and Timezone
-
-You can set the browser's locale and timezone through `CrawlerRunConfig`:
-
-```python
-from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
-
-async with AsyncWebCrawler() as crawler:
-    result = await crawler.arun(
-        url="https://example.com",
-        config=CrawlerRunConfig(
-            # Set browser locale (language and region formatting)
-            locale="fr-FR",  # French (France)
-            
-            # Set browser timezone
-            timezone_id="Europe/Paris",
-            
-            # Other normal options...
-            magic=True,
-            page_timeout=60000
-        )
-    )
-```
-
-**How it works:**
-- `locale` affects language preferences, date formats, number formats, etc.
-- `timezone_id` affects JavaScript's Date object and time-related functionality
-- These settings are applied when creating the browser context and maintained throughout the session
-
-### Configuring Geolocation
-
-Control the GPS coordinates reported by the browser's geolocation API:
-
-```python
-from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, GeolocationConfig
-
-async with AsyncWebCrawler() as crawler:
-    result = await crawler.arun(
-        url="https://maps.google.com",  # Or any location-aware site
-        config=CrawlerRunConfig(
-            # Configure precise GPS coordinates
-            geolocation=GeolocationConfig(
-                latitude=48.8566,   # Paris coordinates
-                longitude=2.3522,
-                accuracy=100        # Accuracy in meters (optional)
-            ),
-            
-            # This site will see you as being in Paris
-            page_timeout=60000
-        )
-    )
-```
-
-**Important notes:**
-- When `geolocation` is specified, the browser is automatically granted permission to access location
-- Websites using the Geolocation API will receive the exact coordinates you specify
-- This affects map services, store locators, delivery services, etc.
-- Combined with the appropriate `locale` and `timezone_id`, you can create a fully consistent location profile
-
-### Combining with Managed Browsers
-
-These settings work perfectly with managed browsers for a complete identity solution:
-
-```python
-from crawl4ai import (
-    AsyncWebCrawler, BrowserConfig, CrawlerRunConfig, 
-    GeolocationConfig
-)
-
-browser_config = BrowserConfig(
-    use_managed_browser=True,
-    user_data_dir="/path/to/my-profile",
-    browser_type="chromium"
-)
-
-crawl_config = CrawlerRunConfig(
-    # Location settings
-    locale="es-MX",                  # Spanish (Mexico)
-    timezone_id="America/Mexico_City",
-    geolocation=GeolocationConfig(
-        latitude=19.4326,            # Mexico City
-        longitude=-99.1332
-    )
-)
-
-async with AsyncWebCrawler(config=browser_config) as crawler:
-    result = await crawler.arun(url="https://example.com", config=crawl_config)
-```
-
-Combining persistent profiles with precise geolocation and region settings gives you complete control over your digital identity.

-# Network Requests & Console Message Capturing
-
-Crawl4AI can capture all network requests and browser console messages during a crawl, which is invaluable for debugging, security analysis, or understanding page behavior.
-
-## Configuration
-
-To enable network and console capturing, use these configuration options:
-
-```python
-from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
-
-# Enable both network request capture and console message capture
-config = CrawlerRunConfig(
-    capture_network_requests=True,  # Capture all network requests and responses
-    capture_console_messages=True   # Capture all browser console output
-)
-```

-1. **API Discovery**: Identify hidden endpoints and data flows in single-page applications
-2. **Debugging**: Track down JavaScript errors affecting page functionality
-3. **Security Auditing**: Detect unwanted third-party requests or data leakage
-4. **Performance Analysis**: Identify slow-loading resources
-5. **Ad/Tracker Analysis**: Detect and catalog advertising or tracking calls
-
-This capability is especially valuable for complex sites with heavy JavaScript, single-page applications, or when you need to understand the exact communication happening between a browser and servers.

-## 7. Network Requests & Console Messages
-
-When you enable network and console message capturing in `CrawlerRunConfig` using `capture_network_requests=True` and `capture_console_messages=True`, the `CrawlResult` will include these fields:
-
-### 7.1 **`network_requests`** *(Optional[List[Dict[str, Any]]])*
-**What**: A list of dictionaries containing information about all network requests, responses, and failures captured during the crawl.
-**Structure**:
-- Each item has an `event_type` field that can be `"request"`, `"response"`, or `"request_failed"`.
-- Request events include `url`, `method`, `headers`, `post_data`, `resource_type`, and `is_navigation_request`.
-- Response events include `url`, `status`, `status_text`, `headers`, and `request_timing`.
-- Failed request events include `url`, `method`, `resource_type`, and `failure_text`.
-- All events include a `timestamp` field.
-
-**Usage**:
-```python
-if result.network_requests:
-    # Count different types of events
-    requests = [r for r in result.network_requests if r.get("event_type") == "request"]
-    responses = [r for r in result.network_requests if r.get("event_type") == "response"]
-    failures = [r for r in result.network_requests if r.get("event_type") == "request_failed"]
-    
-    print(f"Captured {len(requests)} requests, {len(responses)} responses, and {len(failures)} failures")
-    
-    # Analyze API calls
-    api_calls = [r for r in requests if "api" in r.get("url", "")]
-    
-    # Identify failed resources
-    for failure in failures:
-        print(f"Failed to load: {failure.get('url')} - {failure.get('failure_text')}")
-```
-
-### 7.2 **`console_messages`** *(Optional[List[Dict[str, Any]]])*
-**What**: A list of dictionaries containing all browser console messages captured during the crawl.
-**Structure**:
-- Each item has a `type` field indicating the message type (e.g., `"log"`, `"error"`, `"warning"`, etc.).
-- The `text` field contains the actual message text.
-- Some messages include `location` information (URL, line, column).
-- All messages include a `timestamp` field.
-
-**Usage**:
-```python
-if result.console_messages:
-    # Count messages by type
-    message_types = {}
-    for msg in result.console_messages:
-        msg_type = msg.get("type", "unknown")
-        message_types[msg_type] = message_types.get(msg_type, 0) + 1
-    
-    print(f"Message type counts: {message_types}")
-    
-    # Display errors (which are usually most important)
-    for msg in result.console_messages:
-        if msg.get("type") == "error":
-            print(f"Error: {msg.get('text')}")
-```
-
-These fields provide deep visibility into the page's network activity and browser console, which is invaluable for debugging, security analysis, and understanding complex web applications.
-
-For more details on network and console capturing, see the [Network & Console Capture documentation](../advanced/network-console-capture.md).
