Echo 1.0: system monitor in the macOS menu bar
Translated automatically from Russian. Read the original →
Echo — a native macOS menu bar app. System metrics and a few everyday utilities in a single icon.
What’s inside
Monitoring. Clicking the icon opens a window with three rings — CPU, memory, disk — and the current network speed. Each metric has a detailed window: a graph, the heaviest processes by CPU, the hungriest by memory, and the largest files on disk. Any file in the list can be revealed in Finder right away.
Window manager. Halves, quarters, maximize and center — with ⌃⌘ hotkeys plus arrows and letters. A window can be dragged to the edge or corner of the screen, and it will snap there on its own. Holding Shift cancels snapping.
Clipboard history. The most recently copied texts, images and files, via ⌘⇧V. Passwords and temporary entries from password managers don’t end up in the history. Everything is stored in memory only.
Utilities.
- Keyboard Cleaning — locks the keyboard while you wipe it.
- Prevent Sleep — keeps the Mac from sleeping.
- Disk cleanup via the mole command-line utility.
Saves battery
While Echo’s windows are closed, metrics aren’t polled. During system sleep, polling stops; in power-saving mode, it slows down. All of this is configurable. The refresh interval is from 0.5 to 5 seconds.
What it doesn’t do
Echo runs only on your Mac. There are no accounts, telemetry, or network requests for its own needs: metrics and clipboard contents never leave your machine.
How to install
Requires macOS 26.1 or newer. Download Echo-1.0.dmg from the releases page and drag Echo.app into “Applications”. The build isn’t notarized, so on first launch — right-click Echo.app → Open → Open. The window manager needs access in System Settings → Privacy & Security → Accessibility.
