A self-hosted uptime monitoring tool — pings, status pages, and alerts in one polished Vue + Socket.IO app.

What it is

A JavaScript monitoring tool that periodically checks HTTP endpoints, TCP ports, DNS, ping, and other targets, then displays status + alerts in a real-time dashboard. Lightweight enough for a Raspberry Pi; Docker-first deployment. Includes a public status-page feature for incident communication. MIT-licensed.

Key features

Monitor types: HTTP(S), TCP port, ping, DNS, Docker container, gRPC, MQTT, Kafka, Steam game server, more.
Real-time dashboard with WebSocket-driven updates.
Public status pages with custom branding.
Notification channels: Discord, Slack, Telegram, Webhook, email, ~80 others.
2FA, multi-user support.
Lightweight: runs comfortably on a small Pi / VPS.
MIT-licensed.

Tech stack

JavaScript / Vue.js primary.
Socket.IO for real-time updates.
SQLite (or MariaDB) for persistence.

When to reach for it

You want a polished self-hosted uptime monitor for personal / homelab / small-team use.
You want public status pages without Statuspage.io's pricing.

When not to reach for it

You're at scale — Uptime Kuma is single-node; large-scale monitoring wants Prometheus + Alertmanager.
You need enterprise SLA support.

Maturity signal

88k stars, 8k forks, MIT, actively maintained. Open-issues count of 762 tracks the breadth of monitor types + notification channels.

Alternatives

Statping-ng — alternative self-hosted status / uptime tool.
Prometheus + Alertmanager + Grafana — for scale.
Statuspage.io, Better Uptime — commercial managed.
