About auto-cpufreq

auto-cpufreq is an automatic CPU speed and power optimizer for Linux. It watches how charged the laptop battery is, as well as CPU usage, temperature and overall system load, and adjusts frequency governors and turbo behavior to extend battery life without sacrificing performance when it is needed.

It can be used from the command line, with modes such as monitor, live and daemon install, or through a GUI available since version 2.0. Settings can be overridden, for example by forcing a governor or turbo mode, and a config file lets you define behavior per power state. Installation options include an installer script, the Snap Store, an AUR package for Arch-based distributions and NixOS.

The project is written in Python and licensed under GPL-3.0, and the maintainers are looking for co-maintainers and developers via a Discord server. There is also a documentation chatbot for support questions. It suits laptop users on Linux who want automatic power management without hand-tuning governors.
