Hi Product Hunt, I'm Bernard, and I made Tanvas.
I wanted the AI I already code with to design with me in a real file I can open, change and hand to a developer. Not a picture, and not a pile of code.
So Tanvas is a free design app for Mac and Windows where Claude Code, Ollama or Ollama Cloud works on the same canvas as you. Ask for an app and watch it draw the screens, build the components and wire up the prototype. Then it plays the prototype on other phone sizes, spots what breaks and fixes it.
What's in the alpha
A real canvas: auto layout and grids, components with properties, variables and modes, pens and brushes
Effects that look finished: liquid glass, shaders and animated backgrounds
Prototypes you can click through, with interactive components and logic
Handoff: Dev mode code in SwiftUI, Compose, Flutter, React and Tailwind, plus a read-only connection your coding agent can build from
No catch: it's free, there's no account, and your files stay on your computer. Tanvas adds no AI fees; you bring your own.
It's alpha and I ship updates most days, so expect rough edges. I'd love to know what you'd design with it first, and what's missing for you.
