Zed has native support for the Agent Client Protocol (ACP), so you can run Devin CLI as a custom external agent directly inside Zed’s Agent Panel — with real-time editing, syntax highlighting, and agent following.
This integration uses Zed’s built-in support for external ACP agents. For the upstream reference, see the Zed docs on external agents.

​
Setup

1

Install Devin

Open the ACP registry with zed: acp registry from the command palette (Cmd+Shift+P on macOS and Ctrl+Shift+P on Windows). Search for “Devin” and install it.
2

Select Devin in the Threads Sidebar

On the top left corner of the Threads Sidebar, click on the agent dropdown menu and select “Devin”.
3

Authenticate

In the new Devin thread, open the agent menu in the top right corner and select “Authenticate” (or “Reauthenticate”). Then on the bottom of the thread panel, click on “API Key”. A browser window will open, where you can log into your Devin Cloud account and authenticate. If you don’t have an account you can sign up for free!
4

Build with Devin

You can now start a conversation with Devin! By default, Devin will use Adaptive model selection, automatically choosing the best model for your task. You can also pick a specific model from the menu at the bottom of the thread panel.

Notes and limitations

  • Devin CLI’s terminal/shell output is surfaced through Zed’s ACP rendering, which differs from the native Devin CLI terminal UI. Some richer interactions are only available in the standalone CLI.
  • The devin acp subcommand is intended to be launched by an ACP-aware client (like Zed) as a subprocess — it speaks JSON-RPC over stdio and is not meant to be run interactively. See devin acp in the command reference.
