Decode

Decode is in Early Access and brings Claude Code into a browser-based whiteboard for frontend developers. It enables you to view all screens of your locally running app at once, leave comments across UI elements, and have Claude Code review and apply changes directly. The interface is designed for rapid UX feedback and iteration, similar to Figma, but focused on code and live UI.

• Early Access — Decode is currently in Early Access. Features and access may change as the product evolves.
• Claude Code integration — Use Claude Code inside the browser whiteboard to review screens and propose or apply UI changes automatically.
• Browser whiteboard — Load and inspect all screens from a locally running app in a single canvas for fast comparison and navigation.
• Inline commenting — Leave comments and feedback directly across UI elements to capture UX notes and context.
• Instant apply — Claude Code can apply changes it suggests so you can test updates quickly on your local app.

To get started, open the Decode web app, connect it to your locally running application to load screens, create a review session, and add comments on UI elements. Invite Claude Code into the session to run automated reviews and apply edits. Use the whiteboard to iterate visually and validate changes in your local environment.
