Breadboard – A modern HyperCard for building web apps on the canvas
Hey HN! I’m Simone. We re-built Breadboard, a visual app builder that mixes Figma-style UI design with Shortcuts-style logic so you can build, preview, and publish interactive web apps directly from the canvas. What it does Design UIs visually with a flexible canvas –like Figma–. Define app logic with a visual, instruction-stacked editor inspired by Shortcuts. Live preview apps directly on the canvas –no separate preview window–. Publish working web apps with one click. Why we made it Modernize the HyperCard idea: combine layout, behavior, and instant sharing in one place. Reduce friction…
In plain words
Breadboard is a visual web app builder that combines Figma-style interface design with Shortcuts-style logic editing. Users design UIs on a flexible canvas, define app behavior through a visual instruction editor, preview apps live on the same canvas, and publish working web apps with one click. It targets both non-developers seeking simplicity and developers wanting faster workflows, modernizing the HyperCard concept by integrating design, logic, and publishing in a single environment.

Why we made it Modernize the HyperCard idea: combine layout, behavior, and instant sharing in one place. Reduce friction between design and a working app. Make simple web apps approachable for non-developers while keeping power features for developers. Build a foundation for LLM integration so users can design and develop with AI while still understanding what’s happening, even without coding experience –in progress!–.

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:…
