fastCRW

Self-hosted, Rust-native web crawler & scraper for AI agents

The open-source alternative to Firecrawl. One static binary, ~50 MB RAM idle, a native fastCRW REST API under /v1/* (scrape, crawl, map, search, structured extraction, and change tracking), plus a /v2/* Firecrawl compatibility layer for migrations, batch scrape, and PDF parse. Self-host free under AGPL-3.0, or hit our managed API at api.fastcrw.com. Reproducible 63.74% truth-recall on the public 1,000-URL dataset (diagnose_3way.py, 2026-05-08) — see fastcrw.com/benchmarks. Built in Rust because every millisecond of agent latency compounds.
