Robots TXT Checker
Check robots.txt files for crawler directives and blocked paths with validation.
/public//admin//private//api/public/private//A robots.txt file is easy to get subtly wrong in ways a text editor won't ever flag, a Disallow line under the wrong user-agent block, a rule that unintentionally blocks an entire section of a site, a Sitemap directive pointing at a URL that doesn't actually resolve, mistakes that only show up once a crawler starts behaving strangely. This tool validates a robots.txt file's actual structure, listing every user-agent block along with the paths it allows or blocks, and flagging a syntax problem before it quietly affects how a site gets crawled.

Useful for reviewing a robots.txt file after an edit to confirm a whole section wasn't accidentally blocked, checking that a Sitemap directive actually points somewhere valid, or auditing an unfamiliar site's crawler rules to see exactly what's off-limits.
