Devin for Terminal is Cognition’s coding agent for working directly from a terminal. You can install it in an E2B sandbox and use the sandbox as an isolated workspace for agent tasks. To run Devin cloud sessions in isolated E2B sandboxes, see Devin Outposts.

​
Installation

Use a PTY for install and login because Devin’s setup is interactive. You can create a Devin account during sign up if you don’t have one.

​
Usage

After installation and login, use devin -p for non-interactive mode and --permission-mode dangerous to auto-approve tool calls.
Auto-approving tool calls is contained by the sandbox: the agent cannot touch your host machine, local files, or credentials. It can still make outbound network requests — internet access is enabled by default. To limit where an auto-approved agent can connect, configure outbound network rules (allowInternetAccess, plus allow/deny lists by CIDR or hostname). Hostname rules apply to HTTP(S) traffic only; use CIDR rules for other protocols.

​
Example: work on a cloned repository

After installing Devin for Terminal and signing in, clone a repository and run Devin from the project directory.
Devin can edit files, run commands, and work on code inside the sandbox without accessing your local machine.
