CSS + DOM
Visual integrity checks
Detect broken CSS, stale assets, and blank-page regressions that still return a 200.
Monitler
Self-hosted monitoring for failures a 200 status will miss.
Watch uptime, visual integrity, response drift, and recovery paths from one calm surface.

Coverage
One surface for reachability, rendering, and recovery.
Baseline
Healthy-baseline comparison
Every check is measured against how the site looked when it was known good — fonts, colours, structure.
Slack
Slack-first visual alerts
Send noisy CSS and JS failures to Slack so an operator can decide the right manual recovery step.
Workflow
Broken CSS should trigger a response, not just a red badge.
Monitler watches for stale assets, sends Slack context, and lets an operator decide whether cache should be cleared manually.
Detect
Headless Chromium loads each site and compares it against its healthy baseline, so "up" means more than a reachable origin.
Decide
Alert grouping and Slack routing keep noisy failures visible without mutating customer caches automatically.
Resolve
Operators inspect the failed assets, clear cache manually if needed, and let the next check confirm recovery.
