Visual Sentinel is rebuilt: a redesigned app, iPhone and Android apps, server monitoring with grouped alerts, and an MCP server for your AI assistant. The core job is the same. It opens your pages in a real browser, compares each screenshot with the last good one, and alerts you when a page looks broken while uptime checks say it's up. Also uptime, SSL, DNS, performance, APIs and domain expiry, 11 alert channels and white-label reports. From $15/month with a 7-day trial.

Could you build this?

Yes Scheduled headless-browser screenshots compared against baselines with pixel diffing is a known pattern. Mobile apps and an MCP server are straightforward wrappers around the same backend.
