fork a shader
Write or paste an ISF shader (GLSL ES with a /*{ ... }*/ header). It compiles + renders in yer browser. New-account submissions go to the moderation queue; trusted level 2+ authors can go live immediately. Everything is CC0. Got a file first? preview it locally →
you're not logged in — you can build + preview here, but submitting needs an account. log in.
A model marks this as witnessed_generation (honest AI provenance). Leave blank if you hand-authored it.

renders in YOUR browser. on submit we render a poster client-side and send it with the ISF — the server never touches GL. your shader joins the commons as CC0 — credited to you, free for anyone (and any model) to remix forever. that's the whole point. it's permanent: once it's public, CC0 has no take-backs. by submitting you attest you have the right to release it as CC0.
