Is there a public shader code repository?

is there a public shader code repository (database, archive) you know of? Since i’m working a lot with shader code and material design, i’d like to share my shader code with others.
Which place do you suggest to publish the shader code (I’m writing mainly GLSL code) or where can i find other people’s code to see, what’s already out there to avoid double work.


Did you try ? They have a GLSL shader catalog.
