Blender's UI and Runtime: Much Faster Than GPUI

What HN thinks

A thread that came for a UI library and stayed to argue about whether Blender's UI is genius, baby-duck nostalgia, or Claude-written prose.

Blender's UI: love it or hate
Commenters split sharply on whether Blender's interface is polished and elegant or still awkward, with long tangents comparing it to Maya, 3ds Max, Softimage and Inkscape.
LLM-built project raises trust issues
Many found the README obviously AI-written, and some questioned how faithfully the vibe-pruned port reproduces Blender's behaviour, with one tester listing many missing interactions in the web demos.
GPL limits it as a library
Because it derives from GPL Blender code it cannot be LGPL, which several see as a dealbreaker for general-purpose use, while others defend the GPL.

Consensus: No consensus on Blender's UI itself, but most agree the GPL licence and LLM provenance are significant caveats for adopting this as a general UI library.

Recommended in the comments

egui ↗ (library): Cited as a mature, permissively licensed Rust GUI option that benchmarked well.
Iced (library): Named as faster than GPUI in a commenter's benchmark.
Slint (library): Suggested as a Rust GUI alternative, especially for embedded.
UPBGE ↗ (tool): Mentioned for those wanting a Blender-integrated game engine.
KolourPaint (tool): Recommended for basic crop-and-draw on Linux.
Photoflare ↗ (tool): Found more usable than Pinta for simple edits.
