License

The short version: the shader code is MIT licensed. Use it in personal and commercial work, change it as you like, and keep the notice at the top of the file.

Draft. This text has not yet been reviewed by a lawyer and some details are still to be filled in. It describes how the site works today, but it is not final.

Last updated October 14, 2026

What the license covers

The MIT License below applies to the shader code you get from Shadeon: the React and TypeScript components, the JavaScript files, the GLSL fragment shaders, and the small runtime included in them. Each exported file carries a header naming the shader, its version and the license.

What you may do

Use the code in personal, client and commercial projects, without paying.
Change it: colours, behaviour, the GLSL itself.
Ship it inside your product, open source or closed.
Include it in templates and themes that you sell or give away.

What you must do

Keep the copyright and license notice in copies of the code. In practice that means leaving the header comment in the file. It does not need to be visible to your visitors.

What the license does not cover

The Shadeon name and logo. Please do not present your product as Shadeon or as endorsed by Shadeon.
This website itself: its design, text and layout are not licensed for reuse. The shaders are; the site around them is not.
Shaders that may be offered later under a paid plan can have different terms. Those terms will be shown with those shaders. Code you already obtained under the MIT License stays under the MIT License.

No warranty

The code is provided as it is. It is tested, but it comes with no guarantee that it suits your purpose or is free of defects. The license text below and the Terms of Use say this formally.

Where the shaders come from

Every shader is written from scratch for Shadeon. Nothing is copied or ported from other shader collections. Shaders use general, published techniques such as value noise and domain warping; techniques are not anyone's property, and the code that implements them here is our own.

If you believe something on this site infringes your copyright, write to [contact email address] with a link to the material, a description of your work, and your contact details. We will look into it and remove anything that should not be here.
