Robots.txt Checker

Free tool to test if a URL is blocked by robots.txt

Visit

Paste your robots.txt, pick a bot and a URL, and see whether the URL is allowed or blocked, which rule decided it, and any errors. Free, no sign-up. It cannot fetch a live file from another domain, so you paste the contents. Google handles * and $ wildcards but not every crawler does, so confirm in Search Console too.

Features

Allowed or blocked verdict, deciding rule shown, syntax errors flagged, user-agent matching with wildcard fallback, longest rule wins with Allow winning ties, free, no sign-up.

Use Cases

Testing a Disallow rule before deploying it, finding out why a page is not being crawled, checking a staging robots.txt.

Comments

Showing which rule decided the verdict is the useful bit. Most testers just say allowed or blocked and leave you guessing. Since AI crawlers are a common reason people edit robots.txt now, would you consider adding GPTBot, ClaudeBot and similar user-agents to the bot picker?
