Features
Deep insight. Full control. Zero blind spots.
Every feature a modern uptime platform needs, designed so a solo developer and a platform team feel equally at home.
Monitoring
Eight monitor types with the options power users expect.
- HTTP/S with any method, custom headers, JSON or form body, basic or bearer auth, redirect following and custom expected status codes such as 200-299,301
- Keyword checks: alert when text appears or disappears in the response body
- ICMP ping with packet-loss detection and TCP port checks on any port
- DNS record validation for A, AAAA, CNAME, MX, NS and TXT with expected values
- SSL certificate expiry tracking with reminders at 30/14/7/3/1 days
- Heartbeat monitors for cron jobs with configurable grace periods
- Per-region response-time thresholds for slow-response alerts
- Tags, pause/resume, test-before-save and full check history

Detection engine
Built to eliminate false positives without slowing down detection.
- Checks rotate round-robin across the regions selected for a monitor
- Configurable fail threshold (1–10 consecutive failures) per region
- Configurable confirmation: require any number of regions to agree before an incident opens
- Recovery declared only when every region is healthy; incidents record region timeline
- Down monitors re-check every 60 seconds regardless of interval
- Maintenance windows (one-off, daily, weekly, monthly) suppress alerts and exclude downtime from uptime
Regions
5 regions across 4 continents, one lightweight probe image.
- Pick any set of regions per monitor (plan-dependent)
- Every check and incident records the region it was observed from
- Probe workers are stateless Node.js processes: set PROBE_REGION and PROBE_SECRET and start
- Self-host a probe inside your VPC to monitor private services
