In their own words
ddcctl
ddcctl is a free GPLv3 open-source command-line utility for adjusting external monitor controls from the macOS shell. Its primary controls are brightness and contrast. Depending on monitor firmware, it may also switch input source, change built-in speaker volume or RGB colors, select color presets, and reset settings. The stated scope is macOS, Macintosh hardware, and DDC-controlled monitors. Installation is available through Homebrew, downloadable release binaries, or a source build; building requires Xcode and running make. Example scripts can be invoked by Alfred, ControlPlane, or Karabiner to switch presets. The project describes itself as a personal utility in maintenance mode and asks users to debug their own issues. Its maker says there is no time to triage new issues or support non-bugs, and no support or discussion forum is planned. Verification is manual, with no CI connected to real Macs and monitors. The releases page lists v1 as the latest release. The listed controls include DDC/CI, input switching, and command-line access.
