headless-gl is an open-source Node.js library that provides a WebGL rendering context without requiring a browser window or graphical user interface. It enables developers to create and manipulate WebGL contexts directly within server-side JavaScript environments, making it possible to perform GPU-accelerated rendering tasks without launching a full browser. The project aims to conform closely to the WebGL specification so that standard WebGL APIs and shaders can be used in Node.js applications. Because the library runs without a DOM or canvas element, it is particularly useful for headless environments such as servers, automated testing pipelines, or cloud rendering systems. Developers commonly use headless-gl for tasks such as generating images, performing GPU-based computations, or rendering 3D scenes in server-side workflows.
