> Run Devin for Terminal in a secure E2B sandbox.

[Devin for Terminal](https://devin.ai/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](/docs/agents/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.

```bash
e2b sandbox create base

###
# Inside the sandbox
###
curl -fsSL https://cli.devin.ai/install.sh | bash

source /home/user/.bashrc
```

## Usage

After installation and login, use `devin -p` for non-interactive mode and `--permission-mode dangerous` to auto-approve tool calls.

<Note>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](/docs/network/internet-access) (`allowInternetAccess`, plus allow/deny lists by CIDR or hostname). Hostname rules apply to HTTP(S) traffic only; use CIDR rules for other protocols.</Note>

```bash
mkdir -p /home/user/project
cd /home/user/project

devin --permission-mode dangerous -p "Create a hello world HTTP server in Go"
```

## Example: work on a cloned repository

After installing Devin for Terminal and signing in, clone a repository and run Devin from the project directory.

```bash
git clone https://github.com/your-org/your-repo.git /home/user/repo
cd /home/user/repo

devin --permission-mode dangerous -p "Add error handling to all API endpoints"
```

Devin can edit files, run commands, and work on code inside the sandbox without accessing your local machine.
