Version 3.0

Open a coding agent on your Mac, from your phone

If you have Claude Code, Codex or opencode installed on your Mac, you can now open one on the project you already had selected, with a tap. The session runs on your Mac in a real terminal, and you read and type it from your iPhone or iPad. Leave the screen and the agent keeps working; come back whenever you want.

What it brings

  • Agent sessionsPick the agent from a list and your Mac builds the rest: there are no commands to type. Permission prompts show up as they do on your Mac, and you answer them.
  • Several at onceMore than one session per Mac, and you switch between them. Start a new conversation, continue the last one, or pick one from the agent’s own list.
  • The mode belongs to the agentThe app never picks the agent’s mode. To change it, “Mode” sends the same key you would press on the Mac.
  • Build with XcodeBuild, run and test with Xcode from the Run screen with the “Build with Xcode” switch. If the Mac is missing a step, the phone offers to run it.
  • SwiftUI previewsRendered on your Mac, shown on your phone.
  • Xcode’s tools for the whole MacFrom the Mac’s screen, set up building with Xcode, previews, and Xcode’s tools for agents in every project, with a single administrator password on the Mac.
  • Projects grouped by folderThe project list groups projects by folder, great for monorepos.
  • GitThe branch, uncommitted changes, the history, switching branches with a clean tree, and which branches are ahead of or behind their upstream.
  • A home screen with what is going onWhat is running on each Mac and your recent projects, on the first screen.
  • Faster project detailsDetails for a project with Swift packages no longer wait for every package to check for updates.
  • Xcode 27Xcode 27 support, and Xcode 26 stays supported.

What needs the Companion, and what does not

Over SSH, with nothing to install on the Mac, you keep building, testing, distributing, and seeing git. Agent sessions, building with Xcode, previews, and interactive Simulator need Companion 2.0. Want to see a session before installing anything? The app’s Demo Mode runs a complete one, with no Mac and no network.

What the Companion needs

  • A Mac with Apple silicon.
  • macOS 14 Sonoma or later.
  • Xcode installed, with its command line tools ready. Building with Xcode, previews, and Xcode tools for agents need Xcode 26.3 or later.
  • For an agent session: Claude Code, Codex or opencode installed on the Mac, with your account.
  • Both devices on the same local network.
How to get the Companion

As before: no account, no relay, and no CompilePilot server in between. Your device talks straight to your Mac, and your code never leaves it. The agent talks to its own provider, with your account, just as it does on the Mac.
