Ask Claude to audit the site. A built-in MCP server and local API let assistants and scripts run crawls and read the results. How it works

From URL to fixed in three moves

  1. Enter a URL

    Crawlune follows internal links, images, CSS and scripts, respecting robots.txt and your include and exclude rules. Five hundred pages take seconds.

  2. Read the findings

    Issues sit in the sidebar by severity. Click one for the affected URLs, the reason it matters and the fix, with the page source to prove it.

  3. Ship the fixes

    Inspect inlinks, outlinks, headers and HTML per page. Export CSV, generate a sitemap, or turn an issue into a developer ticket.

Free for small sites

Up to 550 URLs per crawl with every check enabled. No account, no trial clock, no watermark on the export.
