What is WebGL Shader Playground?

A live shader editor that lets you write GLSL vertex and fragment shaders and instantly see the visual output rendered via WebGL. Perfect for learning shader programming, prototyping visual effects, or experimenting with GPU-accelerated graphics — all without any local setup.

How to use

1. Write or paste your GLSL fragment shader code into the editor. A default shader is provided to get you started.
2. Watch the live preview update in real time as you type. Built-in uniforms like time, resolution, and mouse position are available.
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 using sine waves and the time uniform, watching the animated result update live in the preview panel.
