Open source web crawler that turns pages into clean Markdown for retrieval pipelines, agents and other LLM data work.

Crawl4AI turns the web into clean, LLM ready Markdown for retrieval augmented generation, agents and data pipelines. It was written because the available web-to-Markdown services wanted an account, an API token and a fee, and still under-delivered.
The library is Python and asynchronous, driving a browser pool with caching and few hops. Markdown generation is pluggable: heuristic filtering strips noise, BM25 pulls the core content, and page links become a numbered reference list with clean citations. There is also a crwl command line tool and a Docker server for the same work.
Beyond Markdown, the crawler is built for extraction under control.
- Structured extraction: schema-based CSS and XPath selectors, or LLM-driven extraction with open source and proprietary models alike.
- Chunking strategies: topic, regex and sentence-level chunking, with cosine similarity to surface the passages a query needs.
- Browser integration: managed and remote browsers over the Chrome DevTools Protocol, persistent profiles, sessions and authenticated proxies.
- Adaptive crawling: learns site patterns and explores only what matters, with deep crawl strategies and a prefetch mode for URL discovery.
- Crash recovery: resume state and state-change callbacks keep long deep crawls restartable.
Install with pip, then run the setup and doctor commands; Playwright's Chromium can be installed by hand if the browser misbehaves. Recent releases have concentrated on hardening the Docker API server, which now enables authentication by default and binds to loopback unless given a token.
No-code platform that turns websites into structured data through recorded robots, crawling, scraping and search, for teams without scraping engineers.

Maxun turns any website into a structured API without anyone writing a scraper. You record what you would do by hand and the platform replays it, which removes the familiar cycle of writing selectors on Monday and repairing them on Friday.
Work is organized around robots, automated agents that navigate a site, pull out information and organize the result the way a person would, only faster. There are four kinds, and together they scale from a single one-off pull to a scheduled pipeline feeding another system.
Each robot type answers a different question.
- Extract: emulates real user behavior to capture structured data, either from a recorded session or from a plain description handled by an LLM.
- Scrape: converts full webpages into clean Markdown or HTML and captures screenshots.
- Crawl: walks an entire site and extracts content from every relevant page, with control over scope and discovery.
- Search: runs automated web searches to discover or scrape results, with time-based filters.
- Document parsing: pulls structured data out of PDF, CSV, XLSX and DOCX files.
Robots handle pagination and scrolling, reach pages behind a login, recover when a site changes its layout, and run on a schedule. Results leave as REST endpoints, exports to Google Sheets and Airtable, or through the SDK and CLI. Self-hosting runs with Docker Compose or a plain local setup, and a hosted version exists for anyone who would rather not operate it.
