robots.txt + sitemap.xml Cross-Validator
Validate robots.txt and sitemap.xml together — including cross-checks (sitemap URL blocked by robots).
About this tool
Paste a robots.txt and a sitemap.xml side by side. The tool parses User-agent groups, Allow/Disallow rules, Sitemap directives and Crawl-delay; validates the sitemap's namespace, URL count, <loc>/<lastmod>/<changefreq>/<priority> fields; and cross-checks every sitemap URL against the robots.txt rules to flag URLs that would be blocked from crawling.
