Mectrics is a free, open-source macOS menu bar utility designed to keep you informed of your Mac's vital statistics at a glance. Developed by Faruk Kamçici, the application puts critical hardware metrics—including CPU, memory, battery, network, disk, GPU, temperature, and fan speeds—directly into your macOS menu bar.

Users have complete control over which metrics are displayed, and clicking an item instantly opens a deeper view of its corresponding statistics. For minimalists, Compact Health folds the entire machine's health into a single menu bar item that stays quiet until something is off. Released under the permissive MIT license, Mectrics requires macOS 15 or newer.
