}Crawlfox runs separate scrapers for Google, Bing, and DuckDuckGo. The engine you pick is the engine you get — same API, same response shape, same price across all three.
Best for AI research agents, SEO and rank tracking, GEO optimization.
Best for Copilot tracking, alternative index, B2B SEO, and ad-tech queries.
Best for privacy-first products, regulated industries, non-personalized research.
The web fights scrapers in dozens of small ways. Crawlfox clears every one of them before your code ever sees a failure — automatically, and continuously improving as the web changes.
Cloudflare, DataDome, Akamai, HUMAN, Imperva, and custom JavaScript challenges — detected and cleared by an engine we wrote, not a vendor we resell.
Residential and datacenter pools, routed per target by our own rotator, with failover the instant an exit is blocked.
Pages that need JavaScript render in a headless browser we built ourselves — not the off-the-shelf automation stack every detector already fingerprints.
Transient failures retry inside the engine. Persistent ones return clean errors, so your code knows when to stop.
Every endpoint has one published credit cost. It doesn’t change for JavaScript rendering or premium proxies, and the credits you buy don’t reset at month-end.
Verified against each provider’s public pricing page or documentation in May 2026.
