A live crawl of g7cloud.com — 3.6 million URLs, 40+ SEO columns, and a full issues breakdown — all in the browser.
Enterprise-grade power. Startup-friendly pricing.
Most SEO crawlers either cap out at a few million URLs or charge thousands per month for scale. CrawlZilla is built from the ground up to handle 100 million+ URL crawls on cloud infrastructure — and our plans start free.
Our distributed architecture scales horizontally — add workers, not workarounds. The same engine that powers a 10,000-URL audit handles 100 million with no configuration change.
Crawl at up to 50 requests per second per session, with multiple sessions running in parallel. That's millions of URLs per hour on a single account.
Free plan with 10,000 URLs. Premium at £39.99/mo for 1M URLs. Ultimate at £79.99/mo for 10M+ URLs. Enterprise for truly unlimited scale. No per-URL pricing traps.
