Check anywebsite.

35 automatic checks of the things that quietly cost sites visitors and trust: security headers, search basics, speed hints, accessibility basics and broken links. Paste an address, get a score and a fix for every problem.

TRY

Public websites only. It makes about twenty requests (the page, robots.txt, the sitemap and a sample of links), introduces itself as sitepulse, and keeps no record of what you check.

UNDER THE HOOD

Open source, and an assistant can use it too.

This page runs sitepulse, a small scanner I wrote. It reads the HTML your server sends and judges it against common good practice. It does not run JavaScript or measure rendering speed, and no automatic check can prove a site is secure or accessible, so treat a warning as a prompt to look, not a verdict.

COMMAND LINE
npx sitepulse your-site.com
CLAUDE CODE (MCP SERVER)
claude mcp add sitepulse -- npx -y sitepulse mcp
