A a highly flexible, customizable, fast and powerful status bar replacement for people that like playing with shell scripts. The main design principle of this project is that all elements of the bar can be added, removed and freely changed at any point in time. Thus, the configuration of the bar is not static, rather it is possible to adapt the appearance of the bar completely dynamically with the help of a powerful event-driven scripting system at any point in time using the highly configurable basic building blocks SketchyBar offers.

The official documentation says to use Homebrew to install it.
