I make fractal art with GLSL and got tired of fighting Shadertoy s limits when I wanted to actually finish and export pieces. So I built the tool I wanted: ShaderKit runs in the browser, fully ShaderToy-compatible, but adds the export pipeline that was missing for me.- Loop examination mode: visualizes the transition point of a looping shader in slow motion so you can see exactly where it breaks. X-time remapping helps debug discontinuities by mapping time to the x coordinate, this way you can see literally if the loop is seamless or not, if you see any seams, its not seamless. This is what I needed most for my own work.- Cloud rendering up to 8K with supersampling- A GIF exporter allowing for setting custom color palettes and choice of dithering algorithmThe main editor and features are free. Cloud rendering is paid because GPU time costs money. There s an optional Claude-based vibe-mode as well.Would especially love feedback on the loop tools from anyone who writes seamless shader loops, that s the part of the problem I think is most under-served.https://shaderkit.com
