Everything a menu-bar uptime app should be
Lightweight, honest, and provider-agnostic — built to feed watch4.me, but genuinely useful with whatever you already run.
Your whole fleet, one glance
The tray icon reflects aggregate up/down at all times. Open the popover for every monitor, with latency and “down for Xm” inline.
Native alerts, only when it matters
A native OS notification fires the moment a monitor flips up↔down — no SMS needed. The first poll sets a silent baseline, so no startup notification storm.
Multi-provider by design
One view across UptimeRobot, Uptime Kuma, BetterStack, Healthchecks.io — and watch4.me as the best-integrated provider. Mix them freely.
A flaky API never fakes an outage
Provider errors map to “Unknown”, not “Down”, after repeated failures — so a hiccup on their side never masquerades as your site going down.
Self-hosted? Point it at your instance
Uptime Kuma and Healthchecks.io take a custom base URL — bring your own instance and UptimeBar watches it like any other.
Quiet, native, always on
A lightweight menu-bar / system-tray app that keeps monitoring even with no window open. macOS (Apple Silicon + Intel) and Windows.
Put your uptime where you can see it.
Free for Mac & Windows. Set up your first monitor in a minute.
