# IndieSitemap > Check a site's sitemap: found through robots.txt, well formed, the URL count, same host, lastmod, and ten sampled pages with their status codes, with the fix for each gap. IndieSitemap is a free, one-input web utility for indie makers at indiesitemap.com. It takes one url, for example https://example.com/, and answers in about ten seconds. Every answer names its source next to it. No account, no card, no premium plan, no upgrade nag, no hidden paywall. Private lookup activity is never published. The site uses cookieless analytics to measure visits. Every page is static HTML, and each link below is that page as Markdown or plain text.
