DumbTerm

A stupidly simple web-based terminal emulator, with common tools and Starship enabled! 🚀

Access your terminal from any device with a web browser
Execute commands just like in a native terminal
Starship prompt provides a beautiful terminal experience with git status, command duration, etc.
PIN protection (recommended) prevents unauthorized access
Use the data directory to persist files between container restarts
Demo mode available for testing and demonstrations - simulated terminal (set DEMO_MODE=true)

Use cases:

Build with docker: To create a sandboxed environment for testing scripts, code, applications, emulate a VPS, showcase examples and more. All without having to install dependencies on your local machine!
Build locally: To access your client's cli/terminal through your browser instead!
Self-hosting: Put behind a reverse proxy, auth provider (like authentik, authelia, etc), Cloudflare tunnels with application access rules, etc for secure external access.
Another alternative to web terminals such as ttyd, shellinabox, etc

Quick Start

Prerequisites

Docker (recommended)
Node.js >=20.0.0 (for local development)
- Windows-specific: WSL or Node.js v16 - Option 3: Running Locally

Option 1: Docker (For Dummies)

Docker method uses a pre-installed Debian Bullseye-based container/environment.

# Pull and run with one command
docker run -p 3000:3000 \
  -v ./data:/root/data \
  -v ./config:/root/.config \ 
  -e DUMBTERM_PIN=1234 \
  -e SITE_TITLE=DumbTerm \
  -e BASE_URL=http://localhost:3000 \
  -e ALLOWED_ORIGINS=http://localhost:3000 \
  -e ENABLE_STARSHIP=true \
  -e TZ=America/Los_Angeles \
  -e LOCKOUT_TIME=15 \
  -e MAX_SESSION_AGE=24 \
  dumbwareio/dumbterm:latest

Go to http://localhost:3000
Enter your PIN if configured
Enjoy your web-based terminal!

Option 2: Docker Compose (For Dummies who like customizing) - Recommended

Create a docker-compose.yml file or use the provided one:

services:
  dumbterm:
    image: dumbwareio/dumbterm:latest
    container_name: dumbterm
    restart: unless-stopped
    ports:
      - ${DUMBTERM_PORT:-3000}:3000
    volumes:
      - ${DUMBTERM_CONFIG:-./config}:/root/.config
      - ${DUMBTERM_DATA_DIR:-./data}:/root/data
    environment:
      # Container timezone
      TZ: ${DUMBTERM_TZ:-America/Los_Angeles}
      # The title shown in the web interface
      SITE_TITLE: ${DUMBTERM_SITE_TITLE:-DumbTerm}
      # Recommended PIN protection (leave empty to disable)
      DUMBTERM_PIN: ${DUMBTERM_PIN:-1234}
      # The base URL for the application
      BASE_URL: ${DUMBTERM_BASE_URL:-http://localhost:3000}
      ENABLE_STARSHIP: ${ENABLE_STARSHIP:-true}
      LOCKOUT_TIME: ${DUMBTERM_LOCKOUT_TIME:-15} # Minutes
      # Session duration in hours before requiring re-authentication
      MAX_SESSION_AGE: ${DUMBTERM_MAX_SESSION_AGE:-24} # Hours
      # (OPTIONAL) - List of allowed origins for CORS
      # ALLOWED_ORIGINS: ${DUMBTERM_ALLOWED_ORIGINS:-http://localhost:3000}

Then run:

docker compose up -d

Option 3: Running Locally (For Developers)

Local method will use your local terminal environment (Windows: Powershell, Mac / Linux: bash).

Install dependencies:

npm install

Tip

Windows specific:

If you encounter issues with node-pty you can try using Windows Subsystem for Linux (WSL) or may need to install:
Node.js v16 (Look into nvm for windows for multi node version support):
- winget install CoreyButler.NVMforWindows
- with nvm installed use: nvm install 16 && nvm use 16
windows-build-tools through Visual Studio Installer MSVC v142 - VS 2019 C++ {arch} Build Tools
- Contact us or View the official Microsoft documentation for more details

cp .env.example .env > Set environment variables in .env:

PORT=3000                  # Port to run the server on
DUMBTERM_PIN=1234          # Optional PIN protection
SITE_TITLE=DumbTerm        # Custom site title
BASE_URL=http://localhost:3000  # Base URL for the application

Start the server:

npm start

Starship usage

Starship is a cross-shell prompt that provides a beautiful terminal experience.
It is enabled by default in the Docker image and is the recommended method.
To disable it, set ENABLE_STARSHIP to false in your environment variables.
You can customize the Starship prompt by using one of the following steps:

1. Use a preset configuration from starship.

Starship Presets:

Tip

copy and paste one of the starship preset commands below into DumbTerm and that's it!

Example Preset Command:

Warning

Note: If running locally or mapped volume to your actual starship.toml config, the preset commands will overwrite your existing starship.toml file. Make sure to back it up as needed.

View All Starship Presets:

Preset Name	Command	Preview
Nerd Font Symbols	`starship preset nerd-font-symbols -o ~/.config/starship.toml`
Bracketed Segments	`starship preset bracketed-segments -o ~/.config/starship.toml`
Plain Text Symbols	`starship preset plain-text-symbols -o ~/.config/starship.toml`
No Runtime Versions	`starship preset no-runtime-versions -o ~/.config/starship.toml`
No Empty Icons	`starship preset no-empty-icons -o ~/.config/starship.toml`
Pure Prompt	`starship preset pure-preset -o ~/.config/starship.toml`
Pastel Powerline	`starship preset pastel-powerline -o ~/.config/starship.toml`
Tokyo Night `(DumbTerm Default with mods)`	`starship preset tokyo-night -o ~/.config/starship.toml`
Gruvbox Rainbow	`starship preset gruvbox-rainbow -o ~/.config/starship.toml`
Jetpack	`starship preset jetpack -o ~/.config/starship.toml`
No Nerd Fonts	`starship preset no-nerd-font -o ~/.config/starship.toml`	n/a

You can also view the available presets by running starship preset -l in DumbTerm.

For more details, visit the Starship Presets page.

2. Modify the `~/.config/starship.toml` file in your set volume mount or within the container.

The default configuration is located in /root/.config/starship.toml.
You can also mount a custom starship.toml file to the container using Docker volumes.
Update or add your custom configurations to starship.toml.
- Visit Starship Configuration for more information on customizing the prompt.

3. Running locally

If you are running DumbTerm locally, DumbTerm will inherit your current styles.
- Meaning if you already have starship enabled locally, you should be able to see your current styles accordingly.
You must install Starship on your local machine if you wish to use DumbTerm with starship locally.
- To install Starship, follow the instructions on the Starship installation page.

Keyboard Shortcuts

DumbTerm provides a comprehensive set of keyboard shortcuts for efficient terminal management. The modifier keys vary by operating system:

Windows/Linux: Ctrl+Alt+{key}
macOS: Ctrl+Cmd+{key}

Action	Windows/Linux	macOS
New Terminal	`Ctrl+Alt+T`	`Ctrl+Cmd+T`
Close Terminal	`Ctrl+Alt+W`	`Ctrl+Cmd+W`
Rename Terminal	`Ctrl+Alt+R`	`Ctrl+Cmd+R`
Search in Terminal	`Ctrl+F`	`Cmd+F`
Next Terminal	`Ctrl+Alt+>` or `Ctrl+Alt+.`	`Ctrl+Cmd+>` or `Ctrl+Cmd+.`
Previous Terminal	`Ctrl+Alt+<` or `Ctrl+Alt+,`	`Ctrl+Cmd+<` or `Ctrl+Cmd+,`
Switch to Terminal 1-9	`Ctrl+Alt+[1-9]`	`Ctrl+Cmd+[1-9]`

Terminal Search

Press Ctrl+F (Windows/Linux) or Cmd+F (macOS) to open the search bar
Use Up/Down arrow buttons or Enter/Shift+Enter to cycle through matches
Press Escape or the close button to exit search mode

Tab Management

Drag and Drop: Click and drag tabs to reorder them
Rename: Double-click a tab or use the keyboard shortcut to rename it
History: Terminal content is automatically preserved across browser refreshes and restarts
Direct Selection: Use number shortcuts (1-9) to quickly switch between the first 9 terminals

Security

It is highly recommended to set a strong PIN, use HTTPS, use ALLOWED_ORIGINS, and integrate with an auth provider (i.e. Authentik / Authelia / tinyauth, etc).

We're dumb, but not stupid. Use a full-featured auth provider for production use.

https://github.com/goauthentik/authentik (More difficult to set up, but production ready)
https://github.com/authelia/authelia
https://github.com/steveiliop56/tinyauth (Easy with docker compose integration)

Variable-length PIN support (numeric)
Constant-time PIN comparison
Brute force protection:
- 5 attempts maximum
