Your Mac's vitals in the menu bar. Free and open source.
CPU, memory, battery, network, disk, GPU, temperature and fans in your menu bar. You pick which ones show, and a click opens the detail behind it. Compact Health folds the whole machine into one item that stays quiet until something's off. MIT, macOS 15+.
Stats proved an open source monitor can be excellent, and iStat Menus set the
depth people expect. I wanted something between the two: free and open, with
alerting I'd actually trust.
The part I use most is Compact Health. It's one menu bar item that summarizes
the whole machine and stays quiet until something needs attention, so I'm not
reading six numbers all day. Alert rules fire on sustained thresholds rather
than momentary spikes, and there's a test delivery so you know what a 3am
notification will look like before it happens.
Everything is read from local system interfaces. No analytics, no crash
reporting; the only network call the app can make is an update check you
trigger yourself.
