Robots.txt Generator & Validator

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.

使い方
