fastCRW vs Firecrawl vs Crawl4AI — at a glance
Sourced from a reproducible 1,000-URL benchmark. For the full p50/p90/p99 latency split — including where fastCRW's tail is slowest — see the benchmarks.
| fastCRW | Firecrawl | Crawl4AI | |
|---|---|---|---|
| Scrape truth-recall¹ | 63.74% (best) | 56.04% | 59.95% |
