Ponzu is an app for making things with Claude: brands, apps, launch pages, diagrams, dashboards, whole features. Each canvas is an infinite board of artboards that Claude draws in plain HTML and CSS while you watch. Pin a comment on anything, and Ponzu makes the change and answers in the thread. A canvas can start from one of your GitHub repositories, where it works on its own branch and you open, check and merge its pull request from the canvas, or from scratch.

Get started

1. Download Ponzu for Mac (Apple silicon, signed and notarized; it updates itself). Windows and Linux builds are in beta on the same page.
2. Sign in with GitHub, then choose where you build: install Ponzu’s GitHub App on your own account or an organization, or use one your team has already set up. Each account Ponzu is installed on is a workspace.
3. Connect Claude: your Claude Pro or Max subscription, or an Anthropic API key. Claude runs on your plan, and Ponzu adds nothing for tokens.
4. Pick a repository or start from scratch.

Ponzu is free while billing is being set up.

On your iPhone
