    DivKit

    DivKit

    DivKit is an open source Server-Driven UI (SDUI) framework

    DivKit is an open source Server-Driven UI (SDUI) framework. It allows you to roll out server-sourced updates to different app versions. Also, it can be used for fast UI prototyping, allowing you to write a layout once and then ship it to iOS, Android, and Web platforms. DivKit is an excellent choice to start using server-driven UI in your project because it can be easily integrated as a simple view in any part of your app. At the starting point, you don’t need a server integration. You can include all JSON on the client-side to try it in a real-world application. Also, we’ve made a sandbox for you to experiment with. You can try different samples in the web editor and see the results on the web or in the Android demo app, both of which are available on Google Play. We’ll publish the iOS demo app shortly. The UI in the demo can be updated live: the sandbox connects to the demo app via web sockets.

    RxBinding

    RxBinding

    RxJava binding APIs for Android's UI widgets

    RxJava binding APIs for Android UI widgets from the platform and support libraries. One of the greatest benefits of using RxJava is the possibility of composing asynchronous events in a simpler and more straightforward way. Complex UI interactions in Android can also be simplified as well, especially when there are multiple UI events that can be triggered. To describe the interaction pattern with standard Android code, you would usually need to use a combination of both listeners, Handlers and AsyncTask. With RxJava and RxBinding, this logic can be greatly simplified and you can describe the interaction patterns between multiple UI components. You can use the RxJava to convert Android view events to Observables. Essentially the library wraps the listener and implements the Observable interface. RxBinding can be indicated as an extension for RxJava, which helps you to use it on Android development simply and easily.

    Showkase

    Showkase

    Annotation-processor based Android library

    Showkase is an Android library developed by Airbnb that helps teams organize, visualize, and manage their Jetpack Compose UI components through an automatically generated component browser. It uses annotation processing to scan the codebase and build a structured interface where developers can explore all composables, colors, and typography in one place. This significantly improves discoverability and reuse of UI elements, which is often a major challenge in large codebases with hundreds of components. Showkase also renders components under different conditions such as dark mode, right-to-left layouts, and scaled fonts, allowing developers to identify issues early in the development process. It integrates seamlessly with existing Compose workflows, including support for preview annotations, and requires minimal configuration to get started.

    Appyx

    Appyx

    Model-driven navigation + UI components with gesture control

    Appyx is a modern navigation and UI framework for Jetpack Compose and Compose Multiplatform that introduces a model-driven approach to building application navigation and interactive interfaces. Unlike traditional navigation libraries that rely on predefined patterns such as back stacks, Appyx allows developers to define their own navigation models, giving them full control over how screens and UI elements transition and interact. This model-driven paradigm separates navigation logic from UI rendering, making navigation state testable, reusable, and easier to maintain in large applications. The framework also supports advanced transition animations and gesture-driven interactions, enabling developers to create highly dynamic and visually rich user experiences beyond standard navigation flows.

    Maestro

    Maestro

    Painless Mobile UI Automation

    Maestro is the simplest and most effective mobile UI testing framework. Maestro is built on learnings from its predecessors (Appium, Espresso, UIAutomator, XCTest) and allows you to easily define and test your Flows. Built-in tolerance to flakiness. UI elements will not always be where you expect them, screen tap will not always go through, etc. Maestro embraces the instability of mobile applications and devices and tries to counter it. Built-in tolerance to delays. No need to pepper your tests with sleep() calls. Maestro knows that it might take time to load the content (i.e. over the network) and automatically waits for it (but no longer than required). Blazingly fast iteration. Tests are interpreted, no need to compile anything. Maestro is able to continuously monitor your test files and rerun them as they change.
