Visual Sentinel

Website monitoring that sees what breaks

Visual Sentinel checks websites like a visitor, not just a ping. It combines uptime, performance, SSL expiry, DNS changes, content tracking, and pixel-level visual monitoring in one workflow. When a page goes down, slows down, changes, or looks wrong while still returning 200 OK, alerts include screenshots, diffs, and diagnostics. Teams can notify email, Slack, Discord, WhatsApp, Telegram, webhooks, and other channels; publish customer-facing status pages; correlate website incidents with server health; and automate through the REST API and MCP server. The permanent Free plan includes three monitors. Eligible users can try Business for 7 days with no card, and paid plans start at $6 per month. Web and Android are available; iOS is still in testing.
