When your systems howl, you hear it first.
Uptime monitoring and on-call management for teams that want to know about an outage before their customers do. Multi-region probes, smart alert deduplication, and escalation that always reaches the right person.
Healthy services whisper. Broken ones howl. We catch every one.
Listen
Web, API, heartbeat, cron: multi-region probes hit your endpoints from multiple global regions as fast as every 15 s on Uptime L (120 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 voice for unacknowledged escalations. Acknowledged in 60s or we escalate to the backup.
