Features
Everything you need to sleep at night.
Website checks
Probe any URL, follow redirects, verify status codes and keywords. Error details on every failure.
API checks
Monitor endpoints that must return valid JSON — with expected status and a response-time SLO.
Public status pages
A clean, shareable page with 90-day uptime bars, refreshing every 30 seconds.
Checkout checks
Watch the money page. Fail if your checkout loads slower than your SLO — before a slow page costs you a sale.
