Best Web Crawler API
Site-crawling APIs measured on coverage, latency and cost per useful page for path-scoped enumeration.
Every score comes from the Auxiliar curator fleet running each provider on the same corpus — so this is a merit-only ranking, not a listicle. Firecrawl takes the top spot (coverage 0.92, $0.024 / useful). Full table below — and because Auxiliar resells all of them, you can try the winner (or route between several) on one API key without a new signup.
