robots.txt Tester

Paste a robots.txt file, choose a user-agent and test any list of URLs against it. The tool applies the same rules Google documents — group selection, longest-match precedence, * and $ wildcards — and shows exactly which rule allowed or blocked each URL.

Runs 100% in your browser — nothing you paste leaves your device.

Notes

  • The most specific (longest) matching rule wins, and on a tie Allow beats Disallow — order in the file does not matter.
  • robots.txt controls crawling, not indexing: a blocked URL can still appear in results if other sites link to it. Use noindex for pages that must stay out.
  • Runs locally in your browser; nothing you paste is sent to any server.
