AirStats is a macOS system monitoring application that places live performance and hardware metrics in the menu bar and can also show them in a detachable panel or as desktop widgets. It is designed to give quick access to common Mac status information such as CPU load, memory pressure, GPU usage, network activity, disk activity, battery status, temperature readings, and active processes, with customizable colors, threshold notifications, and keyboard shortcuts for opening its views. The service is presented as a lightweight, single-process app for Apple silicon Macs running macOS 14 or later, and it is distributed as free, open-source software under the MIT license with no account, trial, or paid tier.
