Sandboxer

Give Claude root access to a disposable machine and let it run autonomously.
Monitor multiple agents live, take over via SSH, or switch to chat UI on mobile.

---

Features

• Live previews - See all Claude sessions at a glance in a scalable grid layout
• Claude Chat - Mobile-friendly chat UI as alternative to terminal view
• SSH takeover - ssh -t sandboxer@host sandboxer-shell to take over any session from terminal
• Session persistence - All sessions survive restarts via tmux
• Claude Loop - Autonomous mode: create PROMPT.md, start loop, Claude works until done

Install

1. Install Claude Code on a dedicated/disposable machine

2. Run:

   claude --dangerously-skip-permissions "clone github.com/anthropics/sandboxer to /home/sandboxer/sandboxer-repo, read CLAUDE.md, then install: deps (python3 tmux ttyd caddy lazygit fzf gemini-cli), copy service files, symlink sandboxer-shell and claude-loop to /usr/local/bin, enable and start services"

3. Access at http://<host>:8080 — default: admin / admin

4. Change password: claude --dangerously-skip-permissions "change sandboxer password to YOUR_PASSWORD"

5. Clone repos: claude --dangerously-skip-permissions "clone github.com/user/repo to /home/sandboxer/git/repo"

Security

Warning: This gives Claude complete control of a machine. Only use on a disposable VM without secrets.

Mobile Access (Terminus/Blink)

Set sandboxer-shell as your SSH client's startup command:

App	Setting
Terminus	Host → Startup Command → sandboxer-shell
Blink	Config → Startup Command → sandboxer-shell

Then connect via SSH — you'll get folder picker → session picker → attached.

Data Storage

All session and message data is stored in SQLite at /etc/sandboxer/sandboxer.db:

Sessions table:

CREATE TABLE sessions (
    name TEXT PRIMARY KEY,
    workdir TEXT NOT NULL,
    type TEXT NOT NULL,        -- 'claude', 'chat', 'bash', 'lazygit'
    mode TEXT,                 -- 'cli' (terminal) or 'chat' (web UI)
    title TEXT,
    claude_session_id TEXT,    -- For Claude's --resume/--session-id
    created_at TEXT,
    updated_at TEXT
);

Sessions use tmux for terminal persistence.
