60FPS smooth, no matter how janky app was due to heavy build/layout

In plain words

This is a performance optimization tool designed to smooth out janky applications caused by heavy builds or complex layouts. Launched in 2022, it targets developers and app creators who need to maintain consistent 60 frames per second rendering. The tool focuses on identifying and fixing performance bottlenecks that cause frame rate drops. It is available as an open-source project on GitHub for anyone building or maintaining applications that experience lag issues.

  ChartGPU – WebGPU-powered charting library (1M points at 60fps)Jan 2026 · github.com · ▲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:…

  Eigendrum - Draw any shape and hear what it sounds like as a drum▲243

  Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

  I 3D scanned the interior of the Great Pyramid at Giza▲1,752

  Hey HN, I 3d scanned the interior of the Great Pyramid &#x2F; Khufu's pyramid for the Giza Project this summer and just finished the guided version to share. Would love feedback and&#x2F;or problems you encounter. I used both a Leica BLK 360 and Matterport Pro 2 to do the scanning and the Matterport SDK for the web viewer. Matterport's web display with Three.js has been the most accessible to a wide audience in the past (previous iterations are in Unity and Unreal, but difficult to download over slower connections). I've been interviewing social studies teachers around the 6th grade level to…

  Restfox – Open source lightweight alternative to Postman▲758

  Last time I posted this it didn't garner much interest. There have been lots of improvements and fixes since the last release. Quick list of features: - Workspaces - Tabs - Nested Folders - Lots of context menus - Response history - Plugins - Runs fully in the browser and runs offline if necessary - Chrome and Firefox extension to bypass CORS restrictions - Desktop builds for all platforms - GraphQL support - Import collections exported from Postman and Insomnia - Simple user friendly interface I built this because I love Insomnia but wanted a portable version that I could run in the…

  America – Road Trip Simulator▲663

  APIs are a little like the open road—always waiting, full of opportunity, but hardly utilized. So here’s America, composed of several APIs that paint a vivid, real-time picture of a good old-fashioned road trip. Get local classifieds and photos. Tune into local radio stations. Talk wit other drivers. And more. Exploring the country by car was an invaluable experience for me during my time in the states. I’ve since moved to Barcelona, and find myself missing the territory. This is my attempt at recreating the magic.
