I've been experimenting (thanks to Claude Code because it removes the headache drastically for me of Rust nuances, I'm not a Rust expert by any means) with Qt and Rust.
I discovered cxx-qt which is maintained by some Qt maintainers, which are all employed at KDAB. I had no idea KDAB or this project existed. It's been very smooth so far.
I can honestly say the barrier to building a GUI is very low with Claude, must to the dismay of others, but it beats me building an Electron app.
I believe when people talk about Rust UI, most people assume it's cross-platform. Developing an app just focused on Mac or Windows is a completely different problem. In fact, one could easily argue that you should never use Rust for those single platform apps.
Only a handful of apps and frameworks have figured this out. Most of the world moved onto HTML+Javascript plus Electron. Or mobile UI.
Who is using native UI in 2026? GTK and QT don't feel great.
I'm glad Zed is trying. We need more efforts.
