description	Use when scraping docs websites into local markdown files, crawling docs, or building AI-readable docs context.

Documentation Scraper

Scrape any documentation website into local markdown files. Uses crawl4ai for async web crawling.

Quick Start

# Scrape any documentation URL
uv run --with crawl4ai python ./references/scrape_docs.py <URL>

# Examples
uv run --with crawl4ai python ./references/scrape_docs.py https://mediasoup.org/documentation/v3/
uv run --with crawl4ai python ./references/scrape_docs.py https://docs.rombo.co/tailwind

Output goes to ./docs/<auto-detected-name>/ by default.

Prerequisites (First Time Only)

uv run --with crawl4ai playwright install

Usage

uv run --with crawl4ai python ./references/scrape_docs.py <URL> [OPTIONS]

Options

Option	Description	Default
-o, --output PATH	Output directory	./docs/<auto-detected-name>
--max-depth N	Maximum link depth	6
--max-pages N	Maximum pages to scrape	500
--url-pattern PATTERN	URL filter (glob)	Auto-detected
-q, --quiet	Suppress verbose output	False

Examples

# Basic - scrape to ./docs/documentation_v3/
uv run --with crawl4ai python ./references/scrape_docs.py \
  https://mediasoup.org/documentation/v3/

# Custom output directory
uv run --with crawl4ai python ./references/scrape_docs.py \
  https://docs.rombo.co/tailwind \
  --output ./my-tailwind-docs

# Limit crawl scope
uv run --with crawl4ai python ./references/scrape_docs.py \
  https://tanstack.com/start/latest/docs/framework/react/overview \
  --max-pages 50 \
  --max-depth 3

# Custom URL pattern filter
uv run --with crawl4ai python ./references/scrape_docs.py \
  https://example.com/docs/api/v2/ \
  --url-pattern "*api/v2/*"

How It Works

1. Auto-detects domain and URL pattern from the input URL
2. Crawls using BFS (breadth-first search) strategy
3. Filters to stay within the documentation section
4. Converts pages to clean markdown
5. Saves with directory structure mirroring the URL paths

Output Structure

docs/<name>/
  index.md           # Root page
  getting-started.md
  api/
    overview.md
    client.md
  guides/
    installation.md

Troubleshooting

Issue	Solution
Playwright browser binaries are missing	Run uv run --with crawl4ai playwright install
Empty output	Check if URL pattern matches actual doc URLs. Try --url-pattern
Missing pages	Increase --max-depth or --max-pages
Wrong pages scraped	Use stricter --url-pattern

Tips

1. Test first - Use --max-pages 10 to verify config before full crawl
2. Check output name - Script auto-detects from URL path segments
3. Rerun safe - Files are overwritten, duplicates skipped
