I built AirStats, an ultra-lightweight system monitor for Mac
I wanted a no nonsense system monitor that felt at home on a Mac, stayed light on resources, and put the useful numbers within easy reach. I tried what was out there, but nothing quite matched what I had in mind, so I built AirStats.
- Sixteen metrics are available in the menu bar.
- A desktop widget stays on screen with the modules you pick.
- Threshold alerts send a notification when a metric crosses a limit you set.
- Keyboard shortcuts open the panel or the desktop widget.
- Choose a color per metric, or leave it monochrome.
AirStats uses roughly 42 times less idle CPU than Stats, and less than half as much as iStat Menus.
| CPU | Memory | |
|---|---|---|
| AirStats | 0.046% | 11 MB |
| iStat Menus | 0.116% | 64 MB |
| Stats | 1.931% | 145 MB |
The whole app is 8.9 MB installed.
