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.
