Native macOS App

Every client site, in your menu bar

Get instant visibility into all your client sites without opening a browser. The Sentinel menu bar app lives in your macOS status bar and shows you the health of every monitor at a glance.

Free to download. Connecting it needs an API token, which is included from the Starter plan ($14/mo) up, so it will not connect on the free plan. Version 1.0.5, macOS 13.0+.

Why a menu bar app?

Passive awareness, not another browser tab

When you're managing dozens of client sites, you need passive awareness, not another browser tab to check. The Sentinel menu bar app gives you at-a-glance status of every monitor right from the menu bar.

  • Always visible in your macOS menu bar
  • Native notifications for instant awareness
  • One-click access to your dashboard

Features

Your monitoring dashboard, always within reach

Menu Bar Icon

A small shield icon in your menu bar shows status at a glance. Optional badge shows the count of active issues.

Text Mode

Switch to text mode for compact counts right in the menu bar: see online, degraded, and offline counts without clicking.

Native Notifications

Get macOS notifications when monitors go down or recover. No browser needed: alerts appear even when you are in other apps.

Quick Dashboard Access

Click any monitor in the popover to jump directly to its detail page in Sentinel. Deep links save you time.

Configurable Refresh

Set your preferred refresh interval from 15 seconds to 5 minutes. Balance between real-time updates and API usage.

Launch at Login

Enable launch at login so Sentinel starts monitoring the moment you open your Mac. Set it and forget it.
