   ChartGPU – WebGPU-powered charting library (1M points at 60fps)▲670

   Creator here. I built ChartGPU because I kept hitting the same wall: charting libraries that claim to be "fast" but choke past 100K data points. The core insight: Canvas2D is fundamentally CPU-bound. Even WebGL chart libraries still do most computation on the CPU. So I moved everything to the GPU via WebGPU: - LTTB downsampling runs as a compute shader - Hit-testing for tooltips/hover is GPU-accelerated - Rendering uses instanced draws (one draw call per series) The result: 1M points at 60fps with smooth zoom/pan. Live demo:…

    Desktop Viewer for WebAssembly Modules▲7

    Hello there, I’m working on a desktop viewer application for WebAssembly modules for Windows, macOS, and Linux, and I’m looking to have some feedback from real-world use. The application is fairly small, requires no installation for now, and is limited to the minimum functionality, but I have more features in mind for the future. Testers would get a free license including future releases. If you’re interested, drop me a mail at [email protected] with the platform(s) you could test on. It would be helpful if you could tell me about in what capacity do you work with WebAssembly,…
