This is much more basic but also considerably smaller.

I really wish libui had more support and momentum. It's literally the only sane cross platform UI project in existence. Everything else is not native (html5 guis), has no accessibility support (all the immediate mode ones), is ancient and ugly (wxwidgets), or is bloated (qt).

[cryo]

Is andlabs/ui still maintained? The last commit is from September 2018. Personally I love Qt since it's modular and I only use (and ship) the parts needed by the application.

It exists since 1995 and is still heavily maintained and modernized over time. I don't know any other GUI cross-platform library like that.

[api]

It's maintained, but by one dev in their spare time as near as I can tell. The parent libui project is in the midst of a refactoring.

We're considering using it for some simple client UI stuff and if we do we plan to make a donation.

This would take a lot of work to be powerful enough for a complex rich UI, but the world needs a basic cross platform UI lib for doing simple interfaces. It's absurd for things like file sync clients and VPN clients to spin up f'ing Electron to provide a UI, but they often do.

This is maintained. libui is the parent project.
