# Cupola

> Cupola is a Mac app that puts terminal coding agents on a whiteboard as cards, next to drawings, sticky notes and images. Each card is a terminal, so Claude Code, Codex, Copilot CLI, Gemini, opencode or any other command-line agent runs in it. It needs macOS 14 or later and an agent CLI installed. It is not released yet.

## Who it is for

Developers on a Mac who run more than one coding agent at a time, such as several Claude Code sessions in different repositories, or Claude Code and Codex on the same project, and want to see them all in one place.

## Questions Cupola answers

- How do I run several Claude Code sessions at once on a Mac?
- How can Claude Code and Codex (or Copilot CLI, Gemini CLI, opencode) work on the same project and talk to each other?
- Which of my coding agents is waiting for me or asking for a permission?
- Is there a visual workspace or canvas for terminal coding agents?
- How do I check on my coding agents from my iPhone or iPad?

## What it does

- Each agent is a card that runs the command the user picks (claude, codex, copilot, gemini, opencode or a shell alias) in a terminal. Claude Code cards can also show a chat view and keep their session between launches.
- Two linked agents can ask each other questions through a local MCP server. An agent reaches only the agents it is linked to. A sticky note reaches its linked agents only when the user sends it.
- Shapes, arrows, pen strokes, text, sticky notes and images share the board with the agents, and agents can draw on it.
- Portals put a web page, an iOS simulator or an Android device on the board, and agents can operate them.
- Each card shows whether its agent is working, done or waiting on a permission prompt. Usage bars show the 5 hour and 7 day limit of each Claude and Codex account.
- Cupola Remote shows the same board on iPad and iPhone over an encrypted connection to the Mac.
- The board is saved as a file on the Mac. Cupola has no account.

## What it is not

- Not an IDE or editor: agents edit files in the user's folders and the user keeps their own editor.
- Not a hosted service: agents run on the user's Mac and talk to their own providers as they do in a normal terminal.

## Platform and availability

- Mac app for macOS 14 or later. Companion app Cupola Remote for iPad and iPhone.
- Not released yet.
