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. -

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. -

Crafty JS
JavaScript Game Engine
Crafty is a JavaScript game engine focused on helping developers build structured, modular 2D HTML5 games that run smoothly in modern browsers. It uses an entity-component system that lets you compose game objects from reusable components instead of relying on inheritance, making game logic easier to organize and maintain. Crafty supports event binding for custom events, so objects can react to game actions, collisions, input, and timers in a clean, decoupled fashion, which helps scale complexity as your game grows. Developers can choose between Canvas or DOM rendering for flexibility in how game elements are drawn, and its lightweight footprint means it won’t slow down load times or performance in most browser environments. The engine is designed to be small and approachable, with enough built-in components for common tasks like movement, collisions, keyboard input, and animations, while still being flexible enough to let developers write their own systems when needed. -

Eva.js
Eva.js is a front-end game engine for creating interactive projects
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! Eva.js is powered by efficient runtime and rendering pipeline (Pixi.JS) which makes it possible to unleash the full potential of your device. Thanks to the ECS(Entity-Component-System) structure, you can expand your needs by highly customizable APIs. The only limitation is your imagination! Eva.js relies on canvas in HTML for drawing. If the width and height in the design draft are fixed (for example, 750px*1000px) and occupy the full screen, we can set the CSS width of the canvas to 100% and the height to auto. -

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. -
