    Matter.js

    Matter.js

    A 2D rigid body physics engine for the web

    Matter.js is a flexible 2D rigid body physics engine written in JavaScript, designed for use in web applications to simulate real-world physical interactions within the browser. It offers a comprehensive set of physics features like gravity, collisions, restitution (bounces), friction, sleeping bodies, and constraint systems that enable developers to build interacting objects with realistic motion. This engine can power everything from dynamic interactive animations and educational simulations to fully fledged physics-based games, and it works across major browsers and devices. Through modules such as Matter.Body, Matter.Composite, and Matter.Constraint, developers can create complex scenes with multiple bodies, jointed structures, and collision responses. Matter.js is popular in the web development community due to its simplicity, extensibility, and rich documentation, allowing both beginners and experienced programmers to leverage physics without deep expertise.

    webmc

    webmc

    PoC Minecraft client written in Javascript

    WebMC is an experimental proof-of-concept Minecraft client written in JavaScript that runs directly inside a web browser. Instead of requiring a traditional desktop installation of the game, WebMC allows users to connect to Minecraft servers from a browser environment. The client communicates with a WebSocket proxy that bridges the browser connection with the standard Minecraft server protocol. By leveraging browser technologies and modern JavaScript libraries, the project demonstrates how a voxel-based game client can run using web-based graphics and networking systems. WebMC also showcases how browser-based applications can interact with multiplayer game servers using real-time communication channels. The project is primarily intended as a technical experiment and educational demonstration of browser-based game development.

    The Tiny JavaScript Game Engine That Can!

    LittleJS is a super lightweight 2D JavaScript game engine with fast WebGL rendering. It is designed to be small, simple, and easy to use for various applications, from game jams to commercial releases.

It is recommended that you start by copying the LittleJS Starter Project This file is mostly empty with just a few things you can use to get started or remove. You can also download and include engine.all.js or engine.all.min.js. In order to load files like images you will need to run a small web server like http-server on npm. I recommend an editor that does this for me automatically like Brackets or VS Code with the Live Server plugin.

    nunuStudio

    nunuStudio

    Web powered cross-platform 3D, WebXR game engine

    nunuStudio is an open-source editor + game development environment — a “studio” rather than just a library — designed to let developers create interactive 2D and 3D content through a user-friendly interface. It provides visual tools for scene editing, asset management, materials, and possibly scripting, aiming to reduce the friction of hand-coding every aspect from scratch. As an accessible entrypoint to game or interactive content creation, nunuStudio is well-suited for artists, designers, or developers who prefer a WYSIWYG (what you see is what you get) workflow instead of fully coding everything. Because it is open source, users can inspect, modify, or extend the system as needed — adding custom behaviors, plugins, or export options. It’s ideal for rapid prototyping, small games or interactive demos, or educational purposes: you can build scenes, tweak visuals, test interactivity without deep diving into all low-level rendering details.

    A front-end game engine specifically for creating interactive game projects. Eva.js provides out-of-box game components for developers to use right away. Yes, it's simple and elegant!
