ShaderKit – A browser GLSL editor I built for my own art
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…
What it does
In the maker’s words, at launch
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 algorithm The 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

- ANA Node Based Editor for Three.js Shading Language (TSL)Jan 2026 · tsl-graph.xyz · ▲7
Three.js recently introduced TSL (Three.js Shading Language), a way to write shaders in pure JavaScript/TypeScript that compiles to both GLSL and WGSL. I built this editor to provide a visual interface for the tsl ecosystem. It allows developers to prototype shaders for WebGPU/WebGL and see the results in real-time. This is a beta release and I'm looking for feedback.

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
