How It Works
Paste your file, run the audit, and test any bot against any path — all in your browser, no login required.
Paste Your File
Copy your existing robots.txt and paste it into the editor. Works with any robots.txt — live sites, staging files, or manually written rules. Load the sample to see an example.
Run the Audit
The validator parses every directive and runs semantic checks — full-site blocks, duplicate groups, missing sitemaps, directives without a User-agent, and syntax errors on every line.
Test Bot Access
Use the Bot Access Tester to confirm whether a specific crawler (Googlebot, GPTBot, AhrefsBot, etc.) is allowed or blocked from any URL path before you deploy your changes.
