What is BUI?

Blender's user interface, as a library you can use from Python, Rust, JavaScript (React, Svelte), C, C++ and Dear ImGui.

People spent decades building and optimizing Blender's GUI. It's battery and memory efficient, and super duper fast. We decoupled it, to give everyone a chance to build their own products with it. It supports multiple languages and frameworks, so you won't miss a beat!
