AgentBox
Run multiple agents in parallel, with a single command, on your PC, self-hosted, or in the cloud
Works with iterm2 - cmux - tmux - Herdr
How it works
agentbox claude # launch a new VM with claude and your project inside
- 📦 Teleport - Move your project to a dedicated VM, local or in the cloud, with a single command.
- 🤖 Automatic - Bring all your skills, plugins, and settings for Claude Code, Codex, Open Code
- 🌐 A full Computer — Dedicated browser, screen sharing, persistent shells and warmed up VS Code / Cursor IDE, with each box.
- 💾 Checkpoints — Sub <1s startup of new boxes from a previous checkpoint, auto pause to save cost/resources when not in use.
- 🔒 Safe - Your git credentials are kept on your local machine, with permission requests to push to the remote repository.
Full Documentation
Complete setup:
npm -g install @madarco/agentbox
agentbox install
# Launch a new VM with claude, copy all your settings and workspace
agentbox claude
# Also install required project libraries and launch your dev server
> Run setup wizard? -> Yes
# Also use a cloud:
agentbox hetzner claude # or vercel, daytona
# Ctrl+a d to detach, claude keep going, to reconnect later:
agentbox attach 1
# To open a persistent shell inside the box:
agentbox shell 1
# Create a second box:
agentbox claude
agentbox attach 2
agentbox shell 2
# Open your web project on a .local url tunnel on your pc
agentbox url 2
# Or the in-box browser via webVNC:
agentbox screen 2
# Or connect to vscode/cursor inside the box:
agentbox code 2
# See status and quickly switch between agents:

Demo
Install
npm -g install @madarco/agentbox
Want to help test what's coming? npm -g install @madarco/agentbox@nightly puts you on the
nightly channel — pre-release builds, with stable releases still
reaching you automatically. agentbox self-update --channel stable opts back out.
Requirements: macOS (arm64 or Intel) or Linux, Docker (Docker Desktop or OrbStack), Node >=20.10. The first agentbox create / agentbox claude builds the agentbox/box:dev image (~1 GB, one-time).
Uses portless to give box web apps the same URL from inside the box and on the host.

Cloud setup (optional — skip for local Docker)
agentbox install — interactive setup wizard to choose which providers to use and configure them.agentbox vercel login — interactive Vercel Sandbox token setup, saved to ~/.agentbox/secrets.envagentbox hetzner login — interactive Hetzner Cloud token setup, saved to ~/.agentbox/secrets.envagentbox daytona login — interactive Daytona API key setup, saved to ~/.agentbox/secrets.envagentbox e2b login — interactive E2B API key setup, saved to ~/.agentbox/secrets.envagentbox digitalocean login — interactive DigitalOcean Personal Access Token setup, saved to ~/.agentbox/secrets.envagentbox remote-docker doctor <host> — run boxes on a machine you already own, over SSH. No login and no token: it connects as you, using your own ~/.ssh/config. Then agentbox docker:<host> claude.agentbox prepare [--provider daytona|hetzner|vercel|e2b|digitalocean|docker:<host>] — build the image and initial snapshot (e2b builds from a Dockerfile via Template.build())agentbox hetzner claude, agentbox hetzner codex, agentbox hetzner create, etc.
How to use
<box> is optional almost everywhere — it defaults to the box for the current project, or use its short index (1, 2, …), name, or id prefix.
Create & run
agentbox create — Create and start a new agent box (Docker container with FUSE overlay)agentbox claude — Create a sandboxed box and launch Claude Code in a detachable tmux session
Access
agentbox url — Open a box's web app URL in the browser (even with no expose: service)agentbox screen — Open a box's VNC (noVNC) viewer in the browseragentbox code — Open a box in VS Code or Cursor via the Dev Containers extensionagentbox shell — Open an interactive bash shell in a boxagentbox open — Open a box's merged workspace in Finderagentbox logs — Print recent log lines from a box service; -f to streamagentbox dashboard — Box list + the selected box's live agent session
Inspect
agentbox list (ls) — List boxes in current project or -g for allagentbox status — Show service + task status from a box's agentbox-ctl daemonagentbox top — Live resource monitor (cpu/mem/pids/disk) for a box, project, or all boxes
Lifecycle
agentbox start — Start a stopped box (docker start + re-mount the FUSE overlay)agentbox stop — Stop a box (preserves the upper volume, node_modules included)agentbox destroy (rm) — Destroy a box and discard its upper volumeagentbox pause / agentbox unpause — Freeze / resume a box (sub-second)
Sync & state
agentbox download — Download a box's /workspace back into your host workspace (gitignore-aware)agentbox cp <src> [dst] — Copy individual files between host and box (like docker cp; direction picked by name: prefix)agentbox checkpoint (alias checkpoints) — List and manage project checkpoints (warm box state to start new boxes from); bare command lists, checkpoint create captures
Advanced
agentbox wait — Block until the box reports all autostart units readyagentbox prune — Clean up orphan state records (and with --all, orphan docker resources)agentbox self-update — Update agentbox, wipe the box image so it rebuilds, reload the relayagentbox config — Read / write layered config (global, per-project, workspace defaults:)agentbox relay — Manage the host relay process (status / stop / start / restart)agentbox app — Control the macOS menu-bar app process (status / start / stop / restart); install it with agentbox install app
Run agentbox <command> --help for command-specific options.
Documentation
Full documentation lives at agent-box.sh/docs:
Development
git clone https://github.com/madarco/agentbox && cd agentbox
pnpm install && pnpm build
node apps/cli/dist/index.js --help
The full development workflow, stack, end-to-end smoke tests, and teardown live in docs/development.md.
The macOS tray app lives in the sibling repo ../agentbox-tray. When you have it checked out next to this repo, these scripts build and run your local dev build (ad-hoc signed, at ../agentbox-tray/AgentBoxTray.app) — separate from the notarized copy agentbox install app puts in /Applications:
pnpm tray:dev # rebuild the dev .app and relaunch it (the one you'll use most)
pnpm tray:build # just rebuild (scripts/make-app.sh)
pnpm tray:start # launch the dev build
pnpm tray:stop # quit any running instance
pnpm tray:restart # quit + relaunch the dev build
Note: agentbox app start|restart targets the installed /Applications copy, not this dev build. Use the pnpm tray:* scripts while iterating on the tray here; run agentbox install app to refresh /Applications from the current CLI build.
Custom providers (plugins)
AgentBox's provider surface is open — you can run agents on your own cloud/infra by shipping a provider plugin (its own npm package built on @madarco/agentbox-provider-sdk), with no changes to AgentBox. Build and test against the bundled example provider locally:
# build the SDK, then build + register the example provider
pnpm --filter @madarco/agentbox-provider-sdk build
cd examples/agentbox-provider-example && npm install && npm run build
node ../../apps/cli/dist/index.js plugin add . # register it
node ../../apps/cli/dist/index.js doctor # shows the provider's group
# verify the SDK artifact in isolation (packs + installs the tarball, asserts exports)
pnpm --filter @madarco/agentbox-provider-sdk pack:test
Full guide: Build a provider (and the authoring reference docs/provider-plugins.md). Reference packages: examples/agentbox-provider-sample (stub) and examples/agentbox-provider-example (a real, Vercel-backed provider).
