FAQ
Are these crawl and audit tools free?
Yes. Every tool on scrawl.tools is free with no login required. Results are ad-free and URLs are not stored beyond the request needed to return your report.
Do I need Screaming Frog for a quick technical check?
For one-off URL checks — broken links, redirect chains, status codes, sitemap health — browser-based tools are enough. Full-site crawls over hundreds of URLs still benefit from a desktop crawler.
