Stremio
Stremio - Freedom to Stream
...It manages add-on installation and configuration in-app, letting users combine official and community sources without leaving the UI. Playback hooks into the stream types exposed by add-ons and the core’s selection logic, with UI affordances for choosing sources, subtitles, and quality. Because the heavy business logic lives in the core, the web app stays focused on UX, routing, accessibility, localization, and smooth state transitions between pages. -

SmsForwarder
Monitors Android mobile phone text messages, calls, and notifications
SmsForwarder is an Android application designed to monitor incoming communications such as SMS messages, phone calls, and app notifications, and then automatically forward them to configured destinations based on user-defined rules, making it ideal for remote monitoring, backup, or automation scenarios. Users can set custom logic so that certain messages or notifications trigger forwarding to group chat bots (like DingTalk or enterprise WeChat), webhook endpoints, email, push services (PushPlus, Bark), Telegram bots, and other channels, allowing flexible integration with communication workflows. In addition to basic forwarding, the app’s rule-based engine can filter messages, enabling selective forwarding based on content, sender, or event type, and it can even push details like call logs or device battery status. ... -

Godot Kotlin JVM
Godot Kotlin JVM Module
...It is built as a module (like the C# binding) to interact with Godot's core internally. The binding provides you Godot APIs as Kotlin classes, so you can write your game logic completely in Kotlin. Your code will be compiled into a .jar which is then executed by an embedded JVM, so you don't have to worry that your users have Java installed. It's already embedded in your game executable. You also don't have to worry about any binding logic. Just write your game scripts like you would for GDScript or C# but with all the syntactic sugar of Kotlin. -

Xenia
Xbox 360 Emulator Research Project
Xenia is an open-source experimental emulator for the Xbox 360 that aims to let users run Xbox 360 games on Windows and other platforms by reverse-engineering the console’s hardware and firmware behavior in software. It implements the 360’s CPU (Xenon), GPU (including Direct3D shader logic), and system libraries to translate Xbox instructions into equivalent host machine operations, enabling many titles to launch and in some cases play at improved frame rates compared with the original hardware. Because Xbox 360 games use custom hardware features and proprietary APIs, Xenia developers have progressively mapped and translated these into PC-friendly code while balancing performance and accuracy, and the project includes compatibility tracking so users can see what games work and how well. ... -

VVVVVV
The source code to VVVVVV
...If you’re looking for the game’s text, that’s mainly (but not entirely) in the Scripts.cpp and TerminalScripts.cpp classes. These functions basically load data into a very simple script parser that controls cutscene logic. All the actual levels in the game are hardcoded in huge arrays generated with a map editor, which exports the levels in source code. Since the 2.0 update, the Windows, Mac and Linux versions of VVVVVV have featured a powerful and easy to use level editor. -

newpipeextractor
Library for extracting streaming site data without official APIs
...NewPipeExtractor provides a unified framework for retrieving information such as video streams, playlists, channels, and search results from supported streaming services. It handles many low-level tasks involved in web data extraction, including parsing responses, managing platform-specific logic, and handling errors, allowing developers to focus on implementing application features rather than scraping mechanics. Each supported service is implemented through its own extractor components that conform to a common interface, enabling consistent access to data across different platforms. -

libsignal
Home to the Signal Protocol and other cryptographic primitives
...Written primarily in Rust with bindings and APIs surfaced for Java, Swift, and TypeScript, this library encapsulates critical algorithms like the Double Ratchet, prekey mechanisms, secure key storage, and zero-knowledge group primitives, along with additional utilities for media handling and device key transfer. libsignal abstracts complex cryptographic constructions into reusable components that client applications can adopt to ensure forward secrecy, authentication, and integrity without re-implementing core security logic. Although its primary use is within the Signal ecosystem, its documentation and exposed interfaces allow developers to explore modern secure messaging primitives or use pieces of the protocol in experimental applications. -

J2ObjC
A Java to iOS Objective-C translation tool and runtime
...This tool enables Java source to be part of an iOS application's build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as application logic and data models) in Java, which is then shared by web apps (using GWT), Android apps, and iOS apps. J2ObjC supports most Java language and runtime features required by client-side application developers, including exceptions, inner and anonymous classes, generic types, threads and reflection. JUnit test translation and execution is also supported. ... -

Java WebSockets
A barebones WebSocket client and server implementation
This repository contains a barebones WebSocket server and client implementation written in 100% Java. The underlying classes are implemented java.nio, which allows for a non-blocking event-driven model (similar to the WebSocket API for web browsers). The org.java_websocket.server.WebSocketServer abstract class implements the server-side of the WebSocket Protocol. A WebSocket server by itself doesn't do anything except establish socket connections though HTTP. After that it's up to your... -

Android Upload Service
Easily upload files in the background with progress notification
...At the core of the library, there is a Service that handles multiple concurrent upload tasks in the background. It publishes broadcast intents to notify status. This way the logic is completely decoupled from the UI. You are safe launching upload requests from your fragments, activities and services without worrying about locking the thread in which you are. Check the wiki to learn how you can use it in your App. You are also safe if your app is put in the background. All the uploads will continue to be executed also when your device is idle. ... -

Redot Engine
Multi-platform 2D and 3D game engine
Redot Engine is an open-source game engine that aims to provide a flexible foundation for building games — likely offering a modern, modular structure so developers can compose only the systems they need (rendering, physics, input, scripting, etc.). It is built to give a base framework rather than a full “batteries-included” engine, which makes it suitable for developers who prefer minimalism, want complete control over architecture, or desire to build custom workflows. Because it’s...
