boxd gives you full Linux computers in the cloud that boot in milliseconds. Every machine gets its own public IP, persistent disk, and HTTPS domain. Whatever you build is immediately live on the internet.

Quickstart

Create your first machine in under 5 seconds.

HTTPS

Automatic domains, configurable proxies.

Control plane

SSH commands, proxy management, JSON output.

Fork

Branch an entire machine in seconds.

What makes boxd different?

Real VMs, not containers. Each machine is a KVM microVM with its own Linux kernel, network stack, and persistent disk. Run systemd, Docker, install kernel modules — no restrictions. Fork entire machines. Copy a running machine — full disk state, installed packages, running services — into a new machine in seconds. Fork before risky changes, fork to test in parallel, destroy the fork when done. Instant HTTPS. Every machine gets name.boxd.sh with TLS terminated at the proxy. Create additional subdomain proxies pointing to different ports. No certs, no DNS, no config. Built for agents. Claude Code and Codex are pre-installed. The in-VM boxd CLI works without SSH keys. Every command outputs JSON. Agents can create, fork, and destroy machines autonomously. Sub-10ms suspend and resume. Machines freeze in place and wake instantly when traffic arrives. Built on Ignition, our open-source microVM engine. No cold starts, no wasted compute. 🇪🇺 European sovereign infrastructure. Hosted on EU hardware with no US cloud dependency. Your data stays in Europe.

Use cases

AI agent sandboxes. Give each agent its own isolated machine with full root, persistent disk, and internet access. Agents manage their own VMs via the boxd CLI — no SSH keys, JSON output, fully autonomous. Fork a known-good state before each task, destroy after. Unlike container-based sandboxes, agents get real hardware isolation with their own kernel. Autonomous coding agents. Claude Code and Codex are pre-installed with a boxd skill that teaches agents the full platform. Agents can spin up machines, deploy apps, configure HTTPS proxies, fork for safe experimentation, and tear down — all without human intervention. Development environments. A full Ubuntu 24.04 machine with Docker, Go, Python, and your editor of choice. Unlike traditional CDEs that take minutes to start, boxd machines boot in milliseconds and persist across sessions. SSH in from anywhere, pick up where you left off. Live demos and prototypes. Deploy an app and share the HTTPS link. No CI/CD pipeline, no hosting config. Your code is live the moment it listens on a port. Parallel testing. Spin up multiple machines to test different configurations, library versions, or approaches simultaneously. Each is fully isolated with its own IP and HTTPS domain. Safe experimentation. Fork your production-like environment, break things, learn, destroy the fork. The original is untouched. This is how agents should work — cheap, disposable branches of entire computers.

​
Every machine includes

  • Ubuntu 24.04 (unminimized, with man pages) — Python 3, Go, Docker, build-essential
  • Claude Code and Codex pre-installed with a built-in boxd skill and CLAUDE.md/AGENTS.md so agents understand the environment out of the box
  • HTTPS domain at name.boxd.sh with configurable proxy routing
  • Public IPv4 — direct SSH, SCP, VS Code Remote, port forwarding
  • 🇪🇺 European infrastructure — hosted on sovereign EU hardware, no US cloud dependency
  • 2 vCPUs, 8 GB RAM, 100 GB disk per machine (extendable on request)
