Free sitemap.xml checker

Paste a site URL (or a full sitemap URL) below. We fetch the sitemap, parse the XML, and list every URL it contains — with quick stats. If your sitemap has errors, we'll surface them. No signup, no credit card.

What this checks

Valid XML, valid namespace, every <loc> resolved to a real URL, no obvious duplicates. The fetch goes through Fastcrawl, so JavaScript-rendered sitemaps (rare) work too.

Build a real sitemap at scale

Fastcrawl's map endpoint crawls a site and returns every URL it finds, including links the sitemap doesn't list. Free tier: 2,000 credits, no card.
