Flipper
A desktop debugging platform for mobile developers
Flipper is a platform for debugging iOS, Android and React Native apps. Visualize, inspect, and control your apps from a simple desktop interface. Use Flipper as is or extend it using the plugin API. Flipper aims to be your number one companion for mobile app development on iOS and Android. Therefore, we provide a bunch of useful tools including a log viewer, interactive layout inspector, and network inspector. Flipper is built as a platform. In addition to using the tools already included, you can create your own plugins to visualize and debug data from your mobile apps. Flipper takes care of sending data back and forth, calling functions, and listening for events on the mobile app. Both Flipper's desktop app and native mobile SDKs are open-source and MIT licensed. This enables you to see and understand how we are building plugins, and of course join the community and help improve Flipper. We are excited to see what you will build on this platform. -

Automation for iOS, Android, and Windows Apps
Appium is an open source test automation framework for use with native, hybrid and mobile web apps. It drives iOS, Android, and Windows apps using the WebDriver protocol. Is native app automation missing from your tool belt? Problem solved.

Awesome Cordova Plugins
Native features for mobile apps built with Cordova/PhoneGap
Awesome Cordova Plugins is a curated set of wrappers for Cordova plugins that make adding any native functionality you need to your Ionic mobile app easy. Awesome Cordova Plugins wraps plugin callbacks in a Promise or Observable, providing a common interface for all plugins and making it easy to use plugins with Angular change detection. In addition to Cordova, Awesome Cordova Plugins also works with Capacitor, Ionic's official native runtime. You also need to install the Awesome Cordova Plugins package for each plugin you want to add. To use a plugin, import and add the plugin provider to your @NgModule, and then inject it where you wish to use it. Make sure to import the injectable class from the /ngx directory. React apps must use Capacitor to build native mobile apps. However, Awesome Cordova Plugins (and therefore, Cordova plugins) can still be used. -

CodePush
Cloud service that enables developers to deploy mobile app updates
CodePush is a cloud service that enables Cordova and React Native developers to deploy mobile app updates directly to their users' devices. It works by acting as a central repository that developers can publish updates to (JS, HTML, CSS and images), and that apps can query for updates from (using provided client SDK for Cordova and React Native). This allows you to have a more deterministic and direct engagement model with your userbase, when addressing bugs and/or adding small features that don't require you to re-build a binary and re-distribute it through the respective app stores. A JavaScript library for programmatically managing your CodePush account (e.g. creating apps, promoting releases), which allows authoring Node.js-based build and/or deployment scripts, without needing to shell out to the App Center CLI. The code-push module exports a single class (typically referred to as CodePush), which represents a proxy to the CodePush account management REST API. -

Detox
Gray box end-to-end testing and automation framework for mobile apps
High velocity native mobile development requires us to adopt continuous integration workflows, which means our reliance on manual QA has to drop significantly. Detox tests your mobile app while it's running in a real device/simulator, interacting with it just like a real user. The most difficult part of automated testing on mobile is the tip of the testing pyramid - E2E. The core problem with E2E tests is flakiness, tests are usually not deterministic. We believe the only way to tackle flakiness head on is by moving from black box testing to gray box testing. That's where Detox comes into play. Detox is built from the ground up to support React Native projects as well as pure native ones. Read the Getting Started Guide to get Detox running on your app in less than 10 minutes. We believe that the only way to address the core difficulties with mobile end-to-end testing is by rethinking some of the principles of the entire approach. -

Drawable Optimizer
Gradle plugin to optimize png files and reduce resultant apk size
drawable-optimizer is a utility focused on reducing the size of Android app image assets to shrink APK/Bundle footprints. It scans res/drawable* and related resource folders and compresses images using configurable strategies, often achieving meaningful savings without visible quality loss. By running as part of the build, it automates a task that would otherwise require manual tooling passes on individual files. Developers can fine-tune which directories and formats to process and exclude sensitive assets where bit-exactness matters. The result is faster downloads, lower install sizes, and improved memory characteristics on resource-constrained devices. It fits naturally into continuous integration, ensuring optimizations remain consistent over time. -

Gradle Android JUnit Jacoco Plugin
Gradle plugin that generates JaCoCo reports
This plugin wires JaCoCo code coverage into Android Gradle projects, generating per-variant coverage reports for unit tests and, when configured, instrumentation tests. It produces HTML and XML outputs that slot neatly into CI pipelines and code quality dashboards. Configuration options let you include or exclude classes (like generated code), merge coverage across flavors and build types, and enforce minimum thresholds to prevent regressions. The plugin integrates cleanly with the Android Gradle Plugin’s task graph, so coverage runs are reproducible across developers and build servers. It helps teams make coverage a first-class metric without hand-crafting custom Gradle tasks for every variant. By lowering setup friction, it encourages frequent measurement and concrete targets for improving test depth. -

NativeScript Angular
Integrating NativeScript with Angular
This repository contains the code for the integration of NativeScript with Angular. NativeScript is a framework that enables developers to write truly native mobile applications for Android and iOS using JavaScript and CSS. Angular is one of the most popular open-source JavaScript frameworks for application development. We worked closely with developers at Google to make Angular in NativeScript a reality. The result is a software architecture that allows you to build mobile apps using the same framework—and in some cases the same code—that you use to build Angular web apps, with the performance you’d expect from native code. Read more about building truly native mobile apps with NativeScript and Angular.
