API for AI agents to search, scrape, crawl, and interact with the live web, returning clean Markdown, structured JSON, or screenshots from any page.

Firecrawl is a web data API built specifically for AI systems. It takes the messy, JavaScript-heavy, human-oriented web and converts it into structured data that agents and LLM pipelines can actually use. Over 80,000 companies rely on it, from indie developers wiring up AI search tools to teams at Apple and Canva running production-scale pipelines.
The three core capabilities work together:
For browser automation for AI use cases, Firecrawl connects directly to MCP-compatible clients like Cursor, Claude, and Windsurf. There's also a CLI and official SDKs for Python, Node.js, Go, Rust, Java, and Elixir.
Under the hood, it covers 96% of the web with a reported P95 latency of 3.4 seconds across millions of pages. The hosted version adds proprietary infrastructure for proxy management and rendering reliability. The self-hostable version is the largest open source repo in the web crawlers space, with over 100,000 GitHub stars.
Common use cases include deep research agents, RAG pipelines, lead enrichment, competitive intelligence, and price monitoring. The free tier covers 1,000 pages per month, with paid plans scaling to millions of pages for larger workloads.
Unlike scraping tools that stop at raw HTML, Firecrawl parses PDFs and DOCX files, extracts structured data against a JSON schema, and caches results against a growing web index. It's a practical fit for any AI workflow that needs reliable, clean input from the live web.
