Open RepenDownload for Mac anyway
Repen for Mac with the Booking flow design open: Claude Code is adding totals to the stay cards on the Stay board, Codex needs an answer on Checkout, and the Agents panel shows Claude Code’s request, its steps, 4 changes to review or undo, and the next request it is working on.

What it adds

More than Repen
in a window.

The app connects the agents already on your Mac, puts each design in a tab, links designs to their code and captures the app you’re running.

  • The Agents panel: Shorter checkout copy needs you, Stay card totals and Colour tokens are working, Welcome copy is ready to review; below it Codex asks to run “pnpm dev --port 3000” in the cove-app folder, with Allow once, Deny and Open.

    Give tasks, follow them

    Ask an agent from the Agents panel. See what needs you, what’s working and what’s ready to review, across every design.

  • On this Mac, 2 found, connected when you opened Repen: Claude Code on your Claude plan and Codex on your ChatGPT plan, both Ready.

    Your agents, already connected

    Repen finds Claude Code and Codex on your Mac and connects them the first time you open it. Nothing to install or paste.

  • Two Repen windows: Brand kit with its colours behind, and in front Booking flow beside a Landing tab, with the Explore and Stay boards.

    Designs in tabs and windows

    Open designs side by side in tabs, or give one its own window. They’re all back the next time you open Repen.

  • Code: linked to cove/booking-app in ~/Code/cove-app, with Open in Cursor, Show in Finder and Show changes; below it 3 files changed in cove-app: screens/Explore.tsx added, components/StayCard.tsx and theme/tokens.ts changed.

    Linked to your code

    Link a design to its code folder. Open it in Cursor, VS Code or Finder, and see the files an agent changed.

  • Capture a page from this Mac: localhost:3000/explore, two servers running on this Mac, the sizes Phone 390, Tablet 834 and Desktop 1440, and Capture.

    Capture what’s running

    Bring a page running on localhost into a board, at phone, tablet or desktop size, and compare it with the design.

  • A new version of Repen is ready: Claude Code is working, so restarting waits until it finishes; Restart when done or When I quit.

    Always up to date

    Repen updates itself in the background, and waits for your agents to finish before it restarts.
