About this tool.

Paste a robots.txt and the tool groups User-agent / Allow / Disallow / Crawl-delay directives, lifts Sitemap URLs to the top, and flags unknown directives, mis-ordered rules, and invalid Sitemap URLs. The path tester picks the most specific User-agent group, applies the longest-match rule with Allow winning ties, and supports the * and $ wildcards.
