Show HN: Sitewatch – fast checks for SSL, DNS, HTTP status, and security headers

https://sitewatch.io/
3•ultra-dev•2d ago
I built Sitewatch because I often want a fast way to sanity-check a site without installing tools, setting up monitoring, or creating an account.

Sitewatch runs instant checks for SSL configuration, DNS resolution, HTTP status, and common security headers. Everything is usable without logging in or providing an email.

The focus is on keeping the checks quick and frictionless. Monitoring and alerts are planned next, but I wanted to share the core tools early to get feedback on what’s useful and what’s missing.

I built this myself and I’ll be around to answer questions or discuss implementation details. Feedback is very welcome.
