Terminal & Code Editor

Every agent comes with two browser-based tools: a code editor (VS Code via code-server) and a web terminal (ttyd). Both are accessed through the dashboard — no local installs needed.

Code editor

The editor is a full VS Code instance running in your browser. Extensions, themes, keybindings, and settings all work as expected.

What works:

• Install extensions from the Open VSX marketplace
• Customize themes and keybindings
• Use the integrated terminal
• Multi-file editing, search, git integration
• All standard VS Code features

What doesn’t work:

• Connecting from desktop VS Code (no SSH or remote tunnel support)
• Extensions that require a desktop environment
• JetBrains or other desktop IDEs

Your editor settings and extensions persist across restarts — they’re stored on the agent’s persistent volume.

Web terminal

The terminal is a full zsh shell with passwordless sudo. Use it like any Linux terminal.

• Default shell: zsh
• Home directory: /home/coder/
• Shell config: ~/.zshrc (persists across restarts)
• Full sudo access — install anything with sudo apt-get install

---

Authentication

Access is managed automatically. When you open the terminal or editor from the dashboard, CrabGlamp generates a short-lived token (60 seconds) and sets a session cookie (24 hours). You don’t need to enter passwords or manage credentials.

If your session expires, refresh the page from the dashboard.

Tips

• Install additional tools with sudo apt-get install <package>. Packages persist across restarts thanks to the overlay filesystem.
• Customize your shell by editing ~/.zshrc. Changes take effect on the next terminal session.
• Browser keyboard shortcuts can conflict with editor shortcuts. Use the editor’s keybinding settings to remap if needed.
• Long-running processes stay alive as long as the agent is running, even if you close the browser tab. They stop when the agent is stopped.
