Turn URLs into clean markdown or structured
JSON with one engine for search, scrape, map, crawl, and extract.
Run it locally as a small Rust binary or use the managed API.

One-command install
Runs local and free, no account needed. To use the Cloud, paste your key into
the same command and it installs the binary, connects the key, and registers the
MCP server with the AI coding tools you already have:
Claude Code, Cursor, Codex, Gemini CLI, OpenCode and Windsurf are picked up
automatically when they are already set up; nothing else is touched, and your
key stays in ~/.config/crw/config.toml rather than being copied into each
tool. Add CRW_NO_AGENTS=1 to skip that step, or run crw setup on its own to
choose interactively.
**1000 free credits, no credit card.** Managed proxies, JS rendering and search,
with nothing to run or keep up to date.

Why fastCRW
On Firecrawl's own public 1,000-URL dataset, fastCRW recovered more truth than
Crawl4AI and Firecrawl, matched the fastest median latency, and idled at
**~14 MB RAM**.
Methodology, full numbers, and how to reproduce it
On a different benchmark entirely, answer accuracy rather than scrape recall,
fastCRW answers **90.0%** of the 600 AA-Omniscience questions correctly. Every
product listed on the Artificial Analysis Search Index sits below it.

MCP for AI agents
Installs the CRW skill and MCP server in your detected AI tools. crw setup can
also do this step, so either path is enough.
