Tauri
A framework for building small desktop apps (and, since Tauri 2, mobile apps) with a web frontend and a Rust backend.
Electron ships a whole copy of Chromium inside every app. Tauri doesn't. It uses the webview the operating system already has, so apps come out much smaller. You build the interface with whatever web framework you like, and Rust handles the native side, like the system tray and notifications. A lot of that native side comes as plugins.
I'm learning Rust and Windows app development at the moment, and Tauri is a big part of that.
I've opened PR #3540 (opens in a new tab) on Tauri's plugins-workspace, with a proposed fix for tauri-plugin-notification on Windows. It's still open, so it's a proposal, not a merged fix.
If you already build for the web, Tauri is a friendly way into desktop apps. And the Rust half is a good excuse to finally learn Rust.
