The glslbin online tool .

This web tool named glslbin can help you to test your shaders online.
Is very simple to use it:

• open the tool;
• delete the source code or change the example;
• run your work ;
• you can also save it.

The development team tell us about this online tool:
glslbin is a fragment shader sandbox similar to ShaderToy or GLSL Sandbox. It's still a work in progress, so expect more to come soon. It adds support for glslify, a GLSL module system which allows you to easily pull in shared code snippets from npm. These modules are all hosted as part of the stack.gl project: you can find a full list of packages in the "Shader Components" section here. Enjoy!
