Rune: A native GPU-rendered Rust UI framework for macOS, Windows, Linux and web

Sort of a digression, but it's the first time I've seen something like this:

    > We don't take pull requests. Have your agent open
    > an issue describing the bug or idea, and our agents
    > usually turn it around fast.

Pretty interesting approach, compared to receiving a zillion potentially sloppy PRs. Open source in the age of LLMs.. ("agent source"?)

> Every app can run headless, so an agent can render to PNG, dump the element tree and drive it with scripted input.

This is cool. I hope SwiftUI / UIKit borrow this idea for native mac apps.

How should I think about this, compared to GPUI (https://gpui.rs)? What are pros and cons?

Looks interesting, especially the headless part. Been building various apps lately for ios/ipados/macos for personal use and I would love something like this that would be truly cross platform. Xcode with agent use has been really nice to work with, and t3.code support for emulators has been amazing to use.

Note the total absence of tests: https://github.com/anomalyco/rune/commits/dev/

So it's a UI framework by agents, for agents?

> native GPU-rendered Rust UI

Sorry, what? I feel like I've studied the Rust UI ecosystem pretty well, and the examples look nice, but if I've learned anything it's that "native" and "GPU-rendered" are oxymoronic.

Likely the fonts will be fuzzy on various platforms, accessibility will be under-baked and it will land in the bucket with every other UI framework depending on winit. I like the personalities at anomaly, but I'm quite confused about what's even driving a decision to build something like this versus contributing to egui, GPUI, Iced, etc.

This is what a vibe coded UI framework looks like.

All the clean code, architecture principles thrown out of the window in favour of hundreds of code smells, anti-patterns and tons of unmaintainable slop.

...what does this do? Is it just a vibecoded version of https://www.egui.rs/
