Uptime monitoring,
stripped to the essentials.

A minimal, self-hostable uptime monitor you can deploy in an afternoon. No sprawling dashboards, no surprise invoices — just the signal.

The parts that matter.
Nothing that doesn't.

Pingback is scoped down on purpose. Register a URL, get a signal when it breaks, ship the fix.

HTTP health checks

Schedule checks against any endpoint from 60s to 60m. Status codes, latency, uptime.

Email that respects you

State-change alerts and daily digests. No pager fatigue — every ping has a reason to exist.

SSL + cert visibility

Watch handshake failures. Stay ahead of outages.

Single binary, single file DB

FastAPI + SQLite. Clone, docker compose up, done. Swap Postgres in when you outgrow it.

Audit log built in

Every user and admin action is middleware-tracked. Useful in debugging, essential for SOC-adjacent asks.

Empty states that teach

First-run onboarding walks you from zero to a green checkmark. The product explains itself.

Deploy it this afternoon.

Docker compose ready. Your first check runs in under a minute.
