When your systems howl, you hear it first.
Uptime monitoring + on-call for teams that can't afford a 4 AM customer ticket. Multi-region probes, smart deduplication, and the gentlest alert path that still wakes someone up.
Healthy services whisper. Broken ones howl. We catch every one.
Listen
Web, API, heartbeat, cron — multi-region probes hit your endpoints from eu-central-1, eu-west-1, and additional regions as fast as every 10 s on Premium (60 s on Free).
Detect
Deduplicated by fingerprint. Three consecutive failures across two regions before anyone gets woken up.
Wake the pack
Escalation policy routes to the on-call. Slack first, then phone. Acknowledged in 60s or we wake the backup.

Teams that sleep through the night
“We dropped PagerDuty for HowlOps the week after the trial. The pack metaphor is corny, but the on-call routing is the cleanest I've used.
“30-second checks on the free tier. Status page that doesn't look like 2009. I run 18 client sites through one dashboard.
“Heartbeat killed a 4 AM cron failure I wouldn't have caught until Monday. Worth the €19/month alone.
Stop guessing whether your status page is lying.
Plug HowlOps in once. Sleep better starting tonight.
