  • "Scan example.com for GDPR compliance basics"
  • "Check the security headers on my site"
  • "Profile this page and tell me what meta tags are missing"

Privacy

URLs sent to a tool are fetched server-side by the mahope.tools scan proxy and not stored. HTML sent to html_to_markdown is converted and discarded immediately.

Releasing

npm run release -- patch (or minor/major) bumps the version, commits and pushes the tag. CI publishes to npm and creates the GitHub release.
