External website monitoring for uptime, performance, SSL, DNS, content, and visual changes. Real-browser screenshot diffs catch broken pages that still return 200 OK. No-code setup, instant alerts, and a free plan.
Maker update, July 21: I refreshed this page with the current owl logo, real product screenshots, and the product as it works today.
Visual Sentinel now checks six layers: uptime, performance, SSL, DNS, content, and rendered-page visual changes. The permanent Free plan includes 3 HTTP + SSL monitors with 10-minute checks from the US and EU. You can also run the public website, SSL, DNS, and speed checkers without creating an account.
Since this launch, we have shipped an Android companion, client-ready monitoring reports, and a 16-tool MCP server for Claude, Cursor, Cline, and Continue. The core promise has not changed: a 200 response does not prove the page your customer sees is okay.
If you are evaluating it, tell me the exact page or failure you need to catch. I am happy to say plainly whether Visual Sentinel fits it.
