there is also a tauri version, we will publish the blogpost about that somewhere in the future.
Also this browser version is not standalone, it still requires one server instance per user that runs deltachat/chatmail core. Ideally it would be just a PWA, but for that #chatmail core needs to be compiled to, and work in wasm: https://support.delta.chat/t/what-would-be-needed-for-a-standalone-web-version-without-a-server-component/3789
