Shaderbang is a Python toolkit for OpenGL rendering using DRM/KMS on Linux. It renders fullscreen without requiring any windowing system, like X or Wayland, making it ideal for embedded systems and headless environments. It is compatible with shaders from Shadertoy, and can be used as a library to build interactive applications.It supports hot-pluggable input devices — keyboard, mouse, touchscreen, and trackpad — via evdev for interactive rendering. Shader files can be made directly executable with shebangs, and Python scripts can embed their dependencies inline as single-file scripts using PEP 723.
