Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

v0.33.0

Published

Launch Claude Code, Codex, and other coding agents in isolated sandboxes

Readme

Run multiple agents in parallel, with a single command, on your PC, self-hosted, or in the cloud

Works with iterm2 - cmux - tmux - Herdr

AgentBox

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:
agentbox dashboard

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 Providers

| | local docker | remote docker | hetzner | daytona | vercel | e2b | | ------------------- | ------------------------- | ---------------------- | ---------------------- | ------------------ | ------------------ | ------------------ | | Support | ✅ | ✅ | ✅ | ⚠️ Partial | ✅ | ✅ | | Base image | Dockerfile | Dockerfile (on the remote) | Setup script (Ubuntu) | Dockerfile | Setup script | Dockerfile (Template.build) | | Live snapshots | ✅ | ✅ (docker commit) | ✅ | 🧪 Experimental | ✅ | ✅ | | Private preview URLs| ✅ (portless or OrbStack) | ✅ (portless over SSH) | ✅ (portless) | ✅ (native) | ✅ (native) | ✅ (native) |

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.env
  • agentbox hetzner login — interactive Hetzner Cloud token setup, saved to ~/.agentbox/secrets.env
  • agentbox daytona login — interactive Daytona API key setup, saved to ~/.agentbox/secrets.env
  • agentbox e2b login — interactive E2B API key setup, saved to ~/.agentbox/secrets.env
  • agentbox digitalocean login — interactive DigitalOcean Personal Access Token setup, saved to ~/.agentbox/secrets.env
  • agentbox 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 browser
  • agentbox code — Open a box in VS Code or Cursor via the Dev Containers extension
  • agentbox shell — Open an interactive bash shell in a box
  • agentbox open — Open a box's merged workspace in Finder
  • agentbox logs — Print recent log lines from a box service; -f to stream
  • agentbox dashboard — Box list + the selected box's live agent session

Inspect

  • agentbox list (ls) — List boxes in current project or -g for all
  • agentbox status — Show service + task status from a box's agentbox-ctl daemon
  • agentbox 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 volume
  • agentbox 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 ready
  • agentbox 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 relay
  • agentbox 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.

Menu-bar tray app (dev)

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).
