Converse Tauri
This is Converse.js (version 9.1.1) in Tauri connecting to any XMPP server through xmpp-proxy.
It's the first known client to support QUIC.
To build install Tauri cargo install create-tauri-app, then run cargo tauri build
If you trust me you can download these binaries, I've only tested the AppImage (arch btw):
