What is WebGL Shader Playground?

Write GLSL vertex and fragment shaders and see the rendered output instantly via WebGL. No local setup needed. Use it to learn shader programming, prototype effects, or try out GPU-accelerated graphics.

How to use

1. Write or paste your GLSL fragment shader code into the editor. A default shader is already loaded.
2. The live preview updates as you type. Built-in uniforms include time, resolution, and mouse position.
3. Export your shader as a PNG screenshot or copy the code to use in your own WebGL projects.

Result

A game developer prototyping a water ripple effect writes a fragment shader with sine waves and the time uniform. The preview panel shows the animated result updating live.
