One-command install

curl -fsSL https://fastcrw.com/install | sh

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:

curl -fsSL https://fastcrw.com/install | CRW_API_KEY=crw_live_... sh

crw search "rust tutorials"

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 CRWNOAGENTS=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. Get my free key →

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.

Shortened. The full README is on GitHub.
