About WebDoctor

WebDoctor is a free kit of website diagnostic tools. The first tool is an XML sitemap validator that checks any sitemap against the official sitemaps.org protocol, the same rules Google, Bing and Yandex crawl by, and explains every finding with a fix.

Why it exists

Most sitemap checkers either dump raw parser output or hide the useful details behind a paywall. WebDoctor aims for the middle: rigorous checks, plain-language explanations, no account, and tools that run in your browser wherever possible.

The toolbox grows over time. A robots.txt tester, redirect chain checker, hreflang checker and meta tag analyzer are next in line.
