/ features

Everything a developer needs.
Nothing else.

The minimum useful monitoring stack — no SRE consultants, no integrations marketplace, no twenty toggles per alert rule.

Multi-region checks

HTTP, ping, and SSL from USA, Europe, and Asia. Add regions as you grow.

Instant alerts

Telegram and email. Smart confirmation prevents false alarms from a single flaky check.

Uptime history

30-day charts, full incident timeline, response-time trends. Honest — for partial periods.

SSL monitoring

Certificate expiry warnings at 30 / 14 / 7 days. Catch silent rotations.

Status pages

Public status page for your users. Custom domain, no badge required.

Developer-friendly

REST API, per-region selection, granular timeouts. curl-ready from day one.

/ pricing

Free while you're small.
Honest when you grow.

Free tier is real, not a trial. Pro and Max are coming soon — no waitlist hostage-taking.
