Breadboard – A modern HyperCard for building web apps on the canvas

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.

From the sources

Stop fighting black-box AI or messy code! Breadboard is an open-canvas app builder where app development feels as visual as Figma. Inspired by Apple HyperCard, you build your app’s brain by attaching natural language logic cards directly to the UI elements they affect. Because our canvas renders real web tech using Auto Layout, your apps are always production-ready and responsive. No broken layouts, no dev-ops. Just build, wire in English, and publish in two clicks - Start Breadboarding!

Bring your design to life by plugging logic directly to UIs on the Figma-like canvas. Ship your web apps with just one click - no complicated setups required! Forget complex syntax. Build logic by stacking simple, readable blocks — just like a to-do list. If you can write a sentence, you can build an app! Import your UI designs or sketch with our style editor & native components. Create high-quality, production-ready interface. Stuck on the logic? We help you generate the perfect prompt to send to any AI model. It's like having a seasoned developer sitting next to you, telling you exactly which block to stack. No servers, no command lines, no headaches. Hit 'Publish' and your app is live,…from breadboards.io

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
