Robots.txt Generator & Validator

Build spec-compliant robots.txt files with a visual editor, or validate existing ones against RFC 9309. Includes presets for common configurations, syntax highlighting, and a URL tester to check if specific paths are blocked or allowed.

How to Use

Switch between Generator and Validator tabs. In Generator mode, pick a preset or build custom rules by adding user-agent groups with allow/disallow paths, crawl-delay settings, and sitemap URLs. In Validator mode, paste your robots.txt content to check for syntax errors, then test specific URLs against the rules.

  • URL Tester – Check if a specific URL is blocked or allowed for any user-agent
  • Crawl-Delay Support – Set crawl delay per user-agent group
