The cloud alternative to Screaming Frog
Screaming Frog is a brilliant desktop crawler. CrawlX runs the same depth of technical audit in the cloud — no install, no memory ceiling — then ranks every issue by impact and ships the fix as a pull request.
Screaming Frog's SEO Spider has been the desktop standard for technical crawling for over a decade, and it's genuinely excellent. CrawlX takes a different shape: it runs in the cloud, so there's no install and no local memory ceiling on big sites; it ranks issues by estimated impact instead of handing you a flat spreadsheet; and it can draft the fix as a GitHub pull request. Here's an honest look at where each tool wins.
