A JavaScript library for making games fast and fun with a powerful component system.
Kaboom is a JavaScript library for making games quickly and enjoyably. It provides tools for graphics, physics, input, and audio with a simple API, solving the complexity of game development boilerplate. It uses a component system to compose game objects and behaviors, enabling rapid prototyping and fun experimentation.
JavaScript developers, hobbyists, educators, and indie game creators looking to build 2D games for the web without heavy frameworks or engine overhead.
Developers choose Kaboom for its simplicity, powerful component system, and fast setup—allowing them to create games with minimal code and maximum fun, backed by a strong community and rich examples.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
With create-kaboom or CDN, developers can start a project and run a dev server instantly, as shown in the README's one-command setup examples.
The component-based approach allows easy composition of game objects from reusable parts like sprites and physics bodies, keeping code intuitive and maintainable.
Kaboom provides out-of-the-box physics for gravity, collisions, and body mechanics, reducing the need for external libraries in simple 2D games.
The library includes a playground, extensive examples, and an active community, facilitating quick experimentation and learning for beginners.
Replit no longer maintains Kaboom, leading to potential bugs, security issues, and lack of new features, though a community fork (KaPlay) exists.
Kaboom is designed solely for 2D game development, making it unsuitable for projects requiring 3D graphics or complex spatial calculations.
Using Kaboom with NPM requires a bundler like esbuild or webpack, adding setup complexity compared to drop-in CDN usage, as admitted in the README.
