6-layer website monitoring: uptime, performance, SSL, DNS, visual regression, and content changes.
Visual Sentinel monitors websites across six layers in a single product. It renders pages in a real Chromium browser and compares screenshots pixel-by-pixel to catch what traditional uptime monitors miss: broken CSS, missing images, or layout shifts that still return HTTP 200 OK.
Works equally well for a single personal site, a small SaaS, or an agency with hundreds of client sites.
