What is Tauri, and why build a desktop app with it?

Why it fits this kind of app

• The UI is React already, and the same code ships as a web app.
• The binary is small, because the webview comes from the operating system.
• Signing and auto update are part of the release path, which matters most on Windows.
• The Rust core handles process management for the daemon and the muse hosts.

The tradeoff

Using the system webview means rendering differences between platforms are yours to handle, where bundling a browser would have hidden them. For an app whose heaviest surface is a thread of text and diffs, that is a good trade.
