MonoBar
Mac app · 2026
MonoBar puts a simple question in the menu bar: is my website up right now? One click shows status, response time, and recent checks. Close the panel and it gets out of the way.
It monitors while your Mac and the app are running. Your monitoring data stays on your Mac, with no account or telemetry. Public service-status feeds help you check whether a provider is having problems too.
The free app monitors one website. MonoBar Pro adds more sites and services, plus local notifications, with a one-time purchase.
