Lunar

brew install --cask lunar v6.10.4

Automatically adjust external monitor brightness based on ambient light or manual control.

Why you might care

Most external monitors lack ambient light sensors, so Lunar fills that gap by using your Mac's sensor to adapt brightness automatically. It also provides convenient keyboard controls for brightness, volume, and input switching—things normally buried in monitor menu buttons. Free and open-source.
