PixiJS

PIXI.js, commonly referred to as PIXI, is an open-source 2D rendering library for the web. It provides a fast WebGL-based rendering pipeline with a Canvas fallback, enabling developers to create interactive graphics, animations, and games using HTML5.

Originating in 2013 as a project by Goodboy Digital, PIXI.js is now maintained by the PixiJS community and ecosystem. It is released under the MIT license, and its source code is hosted on GitHub under the pixijs/pixijs repository.

PIXI.js centers on a scene graph built from display objects such as Container, Sprite, Graphics, and Text. A higher-level Application combines a renderer, stage, and ticker to drive updates. The library supports texture atlases and sprite sheets, animation (including AnimatedSprite), filters and masks, and a robust loader for assets. It runs on WebGL with a Canvas fallback and includes TypeScript definitions. The plugin ecosystem extends functionality with features such as Spine animations, particle effects, and additional renderers.

A typical use case is building browser games, interactive visualizations, or UI components that require smooth, GPU-accelerated rendering. The library emphasizes performance through batching and efficient texture handling and provides extensive documentation, examples, and tutorials.

PIXI.js has a large, active community and ecosystem, with ongoing development and contributions. It is widely adopted in education, indie and commercial projects, and integrates with other web technologies and tooling.
