open-terminal 0.11.26

A remote terminal API.

⚡ Open Terminal

A lightweight, self-hosted terminal that gives AI agents and automation tools a dedicated environment to run commands, manage files, and execute code — all through a simple API.

Why Open Terminal?

AI assistants are great at writing code, but they need somewhere to run it. Open Terminal is that place — a remote shell with file management, search, and more, accessible over a simple REST API.

You can run it two ways:

• Docker (sandboxed) — runs in an isolated container with a full toolkit pre-installed: Python, Node.js, git, build tools, data science libraries, ffmpeg, and more. Great for giving AI agents a safe playground without touching your host system.
• Bare metal — install it with pip and run it anywhere Python runs. Commands run directly on your machine with access to your real files, your real tools, and your real environment, perfect for local development, personal automation, or giving an AI assistant full access to your actual projects.

Getting Started

Docker (recommended)

docker run -d --name open-terminal --restart unless-stopped -p 8000:8000 -v open-terminal:/home/user -e OPEN_TERMINAL_API_KEY=your-secret-key ghcr.io/open-webui/open-terminal

That's it — you're up and running at http://localhost:8000.

[!TIP] If you don't set an API key, one is generated automatically. Grab it with docker logs open-terminal.

Image Variants

	latest	slim	alpine

slim and alpine have the same feature set. Slim uses Debian (glibc) for broader binary compatibility; Alpine uses musl libc and is smaller, but some C-extension pip packages may need to compile from source.

docker run -d -p 8000:8000 -e OPEN_TERMINAL_API_KEY=secret ghcr.io/open-webui/open-terminal:slim
docker run -d -p 8000:8000 -e OPEN_TERMINAL_API_KEY=secret ghcr.io/open-webui/open-terminal:alpine

[!NOTE] Slim and Alpine don't support OPEN_TERMINAL_PACKAGES / OPEN_TERMINAL_PIP_PACKAGES. To add packages, extend Dockerfile.slim or Dockerfile.alpine.

Updating

docker pull ghcr.io/open-webui/open-terminal
docker rm -f open-terminal

Then re-run the docker run command above.

Bare Metal

No Docker? No problem. Open Terminal is a standard Python package:

# One-liner with uvx (no install needed)
uvx open-terminal run --host 0.0.0.0 --port 8000 --api-key your-secret-key

# Or install globally with pip
pip install open-terminal
open-terminal run --host 0.0.0.0 --port 8000 --api-key your-secret-key

[!CAUTION] On bare metal, commands run directly on your machine with your user's permissions. Use Docker if you want sandboxed execution.

Customizing the Docker Environment

The easiest way to add extra packages is with environment variables — no fork needed:

docker run -d --name open-terminal -p 8000:8000 \
  -e OPEN_TERMINAL_PACKAGES="cowsay figlet" \
  -e OPEN_TERMINAL_PIP_PACKAGES="httpx polars" \
  ghcr.io/open-webui/open-terminal

Variable	Description
OPEN_TERMINAL_PACKAGES	Space-separated list of apt packages to install at startup
OPEN_TERMINAL_PIP_PACKAGES	Space-separated list of pip packages to install at startup

[!NOTE] Packages are installed each time the container starts, so startup will take longer with large package lists. For heavy customization, build a custom image instead.

Docker Access

The image includes the Docker CLI, Compose, and Buildx. To let agents build images, run containers, etc., mount the host's Docker socket:

docker run -d --name open-terminal -p 8000:8000 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v open-terminal:/home/user \
  ghcr.io/open-webui/open-terminal

[!CAUTION] Mounting the Docker socket gives the container full control over the host's Docker daemon, which is effectively root access on the host machine. Anyone with access to the terminal can pull/run arbitrary containers (including --privileged ones), mount host directories, access host networking, and manage all containers on the host. Only do this in fully trusted environments.

For full control, fork the repo, edit the Dockerfile, and build your own image:

docker build -t my-terminal .
docker run -d --name open-terminal -p 8000:8000 my-terminal

Configuration

Open Terminal can be configured via a TOML config file, environment variables, and CLI flags. Settings are resolved in this order (highest priority wins):

1. CLI flags (--host, --port, --api-key, etc.)
2. Environment variables (OPEN_TERMINAL_API_KEY, etc.)
3. User config — $XDG_CONFIG_HOME/open-terminal/config.toml (defaults to ~/.config/open-terminal/config.toml)
4. System config — /etc/open-terminal/config.toml
5. Built-in defaults

Create a config file at either location with any of these keys (all optional):

host = "0.0.0.0"
port = 8000
api_key = "sk-my-secret-key"
cors_allowed_origins = "*"
log_dir = "/var/log/open-terminal"
binary_mime_prefixes = "image,audio"
execute_timeout = 5  # seconds to wait for command output (unset by default)

[!TIP] Use the system config at /etc/open-terminal/config.toml to set site-wide defaults for host and port, and the user config for personal settings like the API key — this keeps the key out of ps / htop.

You can also point to a specific config file:

open-terminal run --config /path/to/my-config.toml

Using with Open WebUI

Open Terminal integrates with Open WebUI, giving your AI assistants the ability to run commands, manage files, and interact with a terminal right from the AI interface. Make sure to add it under Open Terminal in the integrations settings, not as a tool server. Adding it as an Open Terminal connection gives you a built-in file navigation sidebar where you can browse directories, upload, download, and edit files. There are two ways to connect:

Direct Connection

Users can connect their own Open Terminal instance from their user settings. This is useful when the terminal is running on their local machine or a network only they can reach, since requests go directly from the browser.

1. Go to User Settings → Integrations → Open Terminal
2. Add the terminal URL and API key
3. Enable the connection

System-Level Connection (Multi-User)

Admins can configure Open Terminal connections for all their users from the admin panel. No additional services required. Multiple terminals can be set up with access controlled at the user or group level. Requests are proxied through the Open WebUI backend, so the terminal only needs to be reachable from the server.

1. Go to Admin Settings → Integrations → Open Terminal
2. Add the terminal URL and API key
3. Enable the connection

Built-in Multi-User Isolation

[!CAUTION] Single-container multi-user mode is not designed for production multi-user deployments. All users share the same kernel, network, and system resources with no hard isolation boundaries between them. If one user's process misbehaves, it can affect every other user on the system. This mode exists as a lightweight convenience for small, trusted groups — not as a security model you should rely on.

For small, trusted deployments you can enable per-user isolation inside a single container:

docker run -d --name open-terminal -p 8000:8000 \
  -v open-terminal:/home \
  -e OPEN_TERMINAL_MULTI_USER=true \
  -e OPEN_TERMINAL_API_KEY=your-secret-key \
  ghcr.io/open-webui/open-terminal

Each user automatically gets a dedicated Linux account with its own home directory. Files, commands, and terminals are isolated between users via standard Unix permissions.

API Docs

Full interactive API documentation is available at http://localhost:8000/docs once your instance is running.

Star History

[!TIP] Need container-per-user isolation? Check out Terminals, which provisions and manages separate Open Terminal containers per user. For lighter deployments, built-in multi-user mode (OPEN_TERMINAL_MULTI_USER=true) provides per-user isolation inside a single container.
