COSMIC is a Wayland desktop environment for Linux that is written in Rust with Smithay and Iced. COSMIC applications are developed with the libcosmic platform toolkit, which is based on iced. They are cross-platform and supported on Windows, Mac, and Redox OS in addition to Linux.
As COSMIC nears its alpha release in Q1 of 2024, we have thus far developed a terminal, file manager, and text editor for our desktop environment within the last few months.

I really like the idea of COSMIC apps and rust powered cross platform dev tools. But I think that the design language of COSMIC so far still needs some polish, so far it seems like there is so much white space, like they’re afraid to show more information on one screen. :(. Also not a fan of rounded corners. I hope this changes soon after it matures a bit.
I don’t think you can say that because we haven’t published our design language yet. Only a handful of design mockups have been published so far. The screenshots here are not design mockups but a work in progress implementation. Hence the “In-progress” part of the title.
Rounded corners are a user preference in the Appearance page in COSMIC Settings.
