Everything you need to catch downtime
The essentials of a dedicated monitoring service, already in your dashboard.
Smart Alerting
Alerts fire after your chosen number of consecutive failures, not the first blip — so you're paged for real outages, not network noise.
- Email, in-app & webhook on down
- Automatic recovery notifications
- 1–10 consecutive-failure threshold
TLS Certificate Monitoring
Every check can track its certificate's expiry alongside uptime, so an expiring cert doesn't take your site down without warning.
- Rechecked automatically every 6 hours
- Independent expiry-warning toggle
- TLS verification on or off per check
History & Incidents
Every probe is recorded, so you can see exactly when something broke, for how long, and how it trended over the last 90 days.
- 24h / 7d / 30d uptime percentages
- 90-day daily availability strip
- Full incident timeline with duration
Built for signal, not noise
Every setting exists to make alerts something you trust, not something you mute.
Alerts you'll actually trust
Down alerts reach you by email, in-app notification, and webhook — and only after your chosen number of consecutive failures, so a single dropped probe will not wake you up. Recovery is announced automatically too.
Flexible match rules
Match on a status-code class, an exact code, or a keyword in the response body — whatever "healthy" means for your endpoint.
Follow redirects
Toggle redirect-following per check, so a 301 to your real health endpoint is not counted as a failure.
Custom timeout
Set anywhere from 1 to 30 seconds, matched to how forgiving your endpoint should be.
Pause anytime
Taking a service down for maintenance? Pause its check with one click instead of deleting it.
On-demand test
Run a check right now from the dashboard, without waiting for the next scheduled probe.
SSRF-hardened prober
DNS-pinned redirects and blocked private ranges — the prober cannot be pointed at internal infrastructure.
Recovery notifications
Get told the moment a failing check comes back up, not just when it goes down.
