What Our Users Say
Automated Screenshots
We take full-page screenshots of your site on every check using a real browser (Playwright + Chromium). Not just HTTP pings.
Pixel-Level Comparison
Detect even subtle visual changes. Layout shifts, missing assets, font changes, color differences — nothing slips through.
Adjustable Sensitivity
Set your own threshold for what counts as a "change." Ignore dynamic content like ads or timestamps while catching real issues.
Instant Visual Change Alerts
Get notified immediately when a visual regression is detected. See a side-by-side diff of what changed.
Screenshot History
Browse historical screenshots to see how your site has evolved. Pinpoint exactly when a visual issue was introduced.
Part of 5-Layer Monitoring
Visual monitoring runs alongside uptime, performance, SSL, and DNS checks. One tool, complete coverage.
Caught in the Wild
These are real production issues detected by Visual Sentinel. No demos, no staging — actual monitoring in action.
