Benchmark GLSL is a small app that allows you to compare the performance of different GLSL code snippets when running as a fragment shader. This app is completely local, none of your code is sent to a server even when you use the Share function. This app is open source released under the MIT license.

Writing Proper Tests
The GLSL compiler is very optimized including dead code elimination and constant statment preprocessing, you need to keep this in mind when writing tests to ensure your code isn't being optimized out. To ensure your code statements aren't constant you must use seed.xyz(Exec function argument) as input for your test calculations, these are real values from 0.0 to 1.0(exclusive) where x = pixel x, y = pixel y, z = frame. Dead code is anything not contributing to the output(Exec return value), return the sum/dot/length of the final computed values to prevent dead code.
