BUI: Blender’s UI as a standalone library
BUI ports Blender widget drawing and interaction into a standalone C-based UI toolkit, with Rust, Python, JavaScript and other bindings. The project reports faster frame times than GPUI in its own benchmarks; those figures should not be treated as independent comparisons.
The repository says its code was entirely LLM-generated, and that some support—including macOS—is experimental. Its README describes GPL-2.0-or-later licensing, while GitHub’s repository badge says GPL-3.0; check the actual license files before relying on either summary.
HN readers liked the prospect of reusing Blender’s interactions, but debated its design and noted GPL compatibility as an adoption consideration.
