ShaderMania

Create, edit, render, share, and learn Metal shaders with ShaderMania for iPad.

ShaderMania is a visual Metal shader editor for iPadOS. Write fragment shaders with realtime preview and playback, organize shaders and images as nodes, connect shader inputs, expose parameters as sliders, and export rendered images.

ShaderMania also includes a public shader library with examples and tutorial shaders, including links to explanation videos where available.

ShaderMania is free to use. Optional tips are available if you want to support development.

A physical keyboard is recommended for coding shaders on iPad.
