What it is

Crawl4AI is an open-source web crawler and scraper that converts HTML into LLM-friendly Markdown for use in RAG pipelines, AI agents, and data extraction workflows. It provides browser automation via Playwright, adaptive crawling strategies, caching, and both Python library and Docker API server interfaces for large-scale web content extraction. Monolithic Python package under crawl4ai/ with specialized submodules: crawl4ai/crawlers/ contains domain-specific scrapers (Amazon, Google), crawl4ai/deep_crawling/ houses traversal strategies (BFS, DFS, BFF), and crawl4ai/cloud/ wraps API server logic. Core crawler logic lives in async_webcrawler.py and async_crawler_strategy.py; supporting…

Start here

Read these in order:

  • crawl4ai/deep_crawling/scorers.py — Foundation: doesn't import anything internally and is imported by 12 other files. Read first to learn the vocabulary.
  • crawl4ai/config.py — Foundation: imported by 9, no internal dependencies of its own.
  • crawl4ai/models.py — Built on the foundation; imported by 28 downstream files.
  • crawl4ai/model_loader.py — Built on the foundation; imported by 2 downstream files.
  • crawl4ai/chunking_strategy.py — Layer 2 — composes lower-level code into reusable abstractions (imported 6×).

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone and install (Python package manager not explicitly listed, but PyPI presence suggests pip): git clone https://github.com/unclecode/crawl4ai && cd crawl4ai && pip install -e . (verify the exact manifest in setup.…

Daily commands:

Development: check for Makefile or pytest configuration in repo root (not listed); likely python -m crawl4ai.cli or python -m uvicorn crawl4ai.main:app --reload after pip install. Production: `gunicorn -w 4 -k uvico…

…shortened for this brief.

Key cautions & unknowns

  • Scorecard: default branch unprotected (0/10)
  • Auth is enabled by default in Docker deployments (v0.9.0 change)—set JWT tokens or bind to loopback only. MemoryAdaptiveDispatcher can leak tasks/pages if streaming crawls aren't properly closed (noted in v0.9.2 fix).…
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
