Tauri is a light and fast electron-esque platform written in rust. I’m pretty bullish on it, as it seems like the best of node and rust without the bloat. Using Svelte to write super light and fast cross-platform apps on Tauri is such a treat.

Those are too hard for beginning programmers. And the Web has all the best-in-class UI design tools (except for maybe Interface Builder, which isn't cross-platform). Plus there's thr fact that Qt apps need extensive cross-platform testing; by contrast, because Chrome works the same way everywhere, so too do Electron apps, so you can deploy to multiple platforms much more quickly.

When it comes to TCO and time to market, none of the non-Web solutions come close to Electron.

I've had not-terrible luck with PyGTK on Win,Mac,Linux. But my apps are simple.
