Features

Observability without the enterprise price tag

Traces, sessions, errors, uptime. Everything you need to understand what's happening in production.

Distributed Tracing

Follow requests across services. See the full waterfall, spot bottlenecks, debug production issues fast.

Real User Monitoring

Session tracking, Web Vitals, frontend errors. See what users actually experience, not just what servers report.

Error Tracking

Errors grouped by fingerprint with stack traces. Linked to the traces and sessions that caused them.

Uptime Monitoring

HTTP health checks and cron job monitoring. Know when endpoints go down or scheduled tasks fail.

Smart Alerts

Slack, Discord, PagerDuty, email, webhooks. Grace periods, recovery alerts, reminders. No alert fatigue.

Status Pages

Public status pages with custom domains. Incidents and maintenance windows. Included free.

Alerts

Get notified where you work

Slack, Discord, PagerDuty, email, webhooks. Set up alerts once and forget about them until something actually needs your attention.

  • Configurable grace periods (no false alarms)
  • Recovery notifications when things come back
  • Reminder intervals for ongoing issues
