    Proton Mail Bridge

    Proton Mail Bridge

    Proton Mail Bridge application

    ...Because standard IMAP cannot natively decrypt end-to-end encrypted messages, Bridge acts as a translator that downloads encrypted mail, decrypts it locally, and serves it to your preferred mail client over a local server, while encrypting outgoing messages before they’re sent to Proton’s servers. It provides a seamless integration layer for users who need offline support, familiar local client workflows, or tighter integration with desktop tools while preserving Proton’s zero-access encryption model. The Bridge app continues running even when its GUI is closed so that mail clients can remain connected and synchronized, and it supports automatic startup and robust credential handling via secure storage.

    Diffuse

    Diffuse

    A music player that connects to your cloud/distributed storage

    ...Diffuse is a static web application, which means it's just HTML, CSS, and Javascript. No REST API, database, or anything backend-related is involved. The app uses a hash (aka. fragment-based) routing system, so you don't need any special server rules for routing. You can download a pre-build web-only version of Diffuse on the releases page. Diffuse uses service workers, so you may need HTTPS for it to work smoothly in certain browsers. I should also note that some source services use OAuth, so you'll need to use your own application credentials (eg. Google Drive client ID + secret).
