About this tool

Sitewatch monitors whether your website actually works — not just whether the server responds. It validates every asset on your pages (scripts, stylesheets, images), checks SSL certificate chains, detects mixed content, verifies security headers, and classifies root causes when something breaks. Get alerts before your users notice, with plain-English diagnosis and fix steps specific to your stack. Free for one site. Free one-time scanner available at getsitewatch.com/scan.
