About Visual Sentinel
What is Visual Sentinel?
Visual Sentinel is a website monitoring tool that watches the page your visitors actually see, not just server uptime. It combines visual change detection with uptime, performance, SSL, DNS, and content checks, alerting you when your site is up but still broken—like a hacked page, a broken button, or a changed price that goes unnoticed.
Who is it for?
It's built for solo developers, SaaS teams, agencies, and ecommerce operators who need to catch issues that basic uptime monitors miss. If you manage client websites or run a production site where visual integrity and trust matter, Visual Sentinel helps you catch and fix problems before customers complain.
Real use cases
Users report catching a rogue crypto miner injected via Magento, or alerting on a plugin update that pushed the 'Buy' button off-screen. Visual Sentinel provides screenshot evidence and alert context so you can jump straight to the fix. It's not for teams that only need simple ping checks—it's for those who need deep, evidence-rich monitoring.
Key features
- Visual change detection — Alerts you when the page visibly changes, even if uptime shows 200 OK.
- Multi-layer monitoring — Combines uptime, performance, SSL, DNS, and content checks in one incident.
- Incident replay — See baseline vs. current screenshots and diff to understand exactly what changed.
- 10 alert channels — Get notifications via email, Slack, Discord, Telegram, WhatsApp, and more.
- Multi-region checks — Monitors from US and EU regions for accurate global availability.
- Evidence-ready reports — Capture screenshots and diagnostics together for easy sharing with your team or clients.
