uptime.ooo

uptime.ooo watches your sites, APIs, and background jobs from six regions and pages the person actually on call when something breaks. The app carries the part that matters at 3am: the alert reaches your lock screen, and one tap acknowledges it and stops the escalation ladder without opening anything.

• Every monitor with 30 days of uptime at a glance
• Response-time trends, percentiles, and per-region results
• Incidents with the full escalation timeline — who was paged, how, and whether it landed
• Acknowledge from the lock screen
• A war room per incident, and team chat rooms
• Who's on call now and who's next
• Status pages and scheduled maintenance

Requires an uptime.ooo account. Self-hosted servers work too — set your own server URL on the sign-in screen.
