robots.txt Checker
Read and display a site's robots.txt to verify crawler rules.
The WebURL robots.txt Checker is a free online tool, no signup required, that reads and displays any site's robots.txt — use it to verify crawler rules aren't blocking important pages or AI crawlers.
About this tool
The robots.txt checker fetches and parses a site's robots.txt, showing every rule: allowed paths, disallowed paths, sitemap locations and rules targeting specific crawlers such as GPTBot or Googlebot.
Use it on your own site before launch to confirm no important directory is accidentally blocked; use it on competitors to see how open they are to AI crawlers.
A stray Disallow: / is one of the most common launch-day mistakes - keep this check on every pre-launch list.
