Dear all, ever missed a Crystal native GUI framework? Maybe you want to check out CrymbleUI . From the README.md: A nice and fast GUI framework for Crystal. Declarative and reactive. Its name is a pun of Crystal and nimble :smiley: CrymbleUI’s first line of code emerged 2.11.2025, 19:46. Curren…

@weirdbricks SFML does support Mac as well, it’s just I don’t have one and cannot supply default binaries for it - but maybe you can?

Looks still early on, but you could at some point utilize GitHub Actions to generate binaries. I use it for a few Crystal projects. It’s helpful for finding compile issues cross platform as well. I generally have Mac, Linux arm64/amd64, and FreeBSD amd64 generate with each release. Probably stil…

Thank you! I’ll give it a shot when I have a chance

@Kritoke thanks for the hint, maybe someday later I will come around and manage to have a look :slight_smile:

good take - seems like I missed it - I really had some tough fights with CC the last weeks :slight_smile:

Looks nice. Are you using this in any projects?

Looks awesome, congrats. There is an old but active GUi libs thread, State & Plans of GUI development with Crystal. I think it’d be nice to post this there, too.
