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 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!–.
Try it –no signup required–
