What
Adds fastCRW as a web scrape/search provider, alongside the existing Firecrawl integration — additive only, Firecrawl untouched.
Why
fastCRW is a self-hostable, fully open-source (AGPL) web engine — single ~8MB Rust binary, ~6MB RAM.
Runs 100% locally with full capability. Anti-bot/stealth, BYO-proxy + rotation, and JS rendering (Cloudflare JS-challenge, SPA) all ship in the open core. Firecrawl's OSS self-host gates its stealth engine (
fire-engine) behind a cloud-only flag, so its self-hosted instance falls back to plain fetch/Playwright and can't reliably reach protected or JS-heavy pages. fastCRW's open binary has no such gap.Faster and higher-recall on Firecrawl's own benchmark dataset. Truth-recall 63.74% vs 56.04%; median latency p50 ~1.9s vs ~2.3s. One binary, no multi-service stack.
Search is SearXNG-backed with added reranking and multi-round retrieval for higher-quality results.
Key via
CRW_API_KEY(free tier at https://fastcrw.com/dashboard); self-host base URL supported. Happy to adjust to your conventions — I maintain the integration and can provide free credits to evaluate.Because fastCRW is Firecrawl-API-compatible, the integration diff is tiny and purely additive — that's why it mirrors the Firecrawl wiring with minimal code.
