    Amethyst Nostr client for Android

    Amethyst Nostr client for Android

    Nostr client for Android

    ...The overall architecture consists of the UI, which uses the usual State/ViewModel/Composition, the service layer that connects with Nostr relays, and the model/repository layer, which keeps all Nostr objects in memory, in a full OO graph. The repository layer stores Nostr Events as Notes and Users separately. Those classes use LiveData objects to allow the UI and other parts of the app to subscribe to each individual Note/User and receive updates when they happen. They are also responsible for updating viewModels when needed. Filters react to changes in the screen. As the user sees different Events, the Datasource classes are used to receive more information about those particular Events.

    Proton Drive SDK

    Proton Drive SDK

    SDK repository intended to provide reusable client libraries

    Proton Drive SDK is Proton’s dedicated SDK repository intended to provide reusable client libraries for integrating Proton Drive capabilities into other applications, with an initial focus on a JavaScript SDK and plans for a C# SDK. The repository is explicitly labeled as a work in progress and notes that it is not ready for use yet, which signals that public APIs and stability guarantees should not be assumed at this stage. Its implementation is predominantly TypeScript, which is well-suited for producing strongly typed JavaScript libraries that can be consumed across modern web and Node.js environments. By centralizing shared SDK logic in a single repo, Proton can standardize how third-party or internal clients interact with Proton Drive’s protocols and behaviors, reducing duplication and improving consistency across platforms over time.

    SubsCheck-Win-GUI

    SubsCheck-Win-GUI

    A GUI program interface designed by SubsCheck for Windows users

    ...The application provides a user interface for loading subscription links or node lists, performing checks (e.g., reachability, latency), and presenting results in a user-friendly view. It also supports auto-update of version information and links to downloads, as evidenced in its release notes (version 2.0.1.7 optimizing update mechanism). The tool caters to those who may prefer a desktop environment rather than deploying and debugging worker scripts themselves; it fills the niche of “subscription manager” on Windows. Because it deals with subscription feeds (for proxies), it also indirectly supports workflows similar to the WorkerVless2sub project but focused on the client/desktop side rather than backend generation.
