Box

Box is the cheapest, most powerful sandbox for AI agents — built for agent factories who need persistent, programmable Linux environments without the complexity or cost of traditional cloud infrastructure. Spin up full Ubuntu virtual machines with SSH access, Docker support, dedicated IPv4 addresses, and 60fps virtual desktops in seconds, then pause billing instantly when done.

Product Highlights

• Agent-First CLI: A purpose-built command-line interface designed for programmatic use, AI agents, and human developers alike — spin up, fork, and manage boxes with simple commands.
• Pre-Configured Environment: Every box ships with Docker, VS Code, Chrome, Ghostty, GitHub CLI, Rust, Node.js, and Bun pre-installed — run any devtool, language, or workflow immediately.
• Persistent & Forkable: Full Ubuntu machines with fast disk-level forking from snapshots; stop to pause billing and resume in seconds with all files, packages, and services intact.
• Dedicated Resources: Each box includes a dedicated IPv4 address, 60fps virtual desktop access, and full machine capabilities — not containerized limitations.
• Honest Pricing: Pay only for running boxes, billed by the second with a $20 monthly minimum that converts to ~555 hours of 4 vCPU / 8 GB VM time across any number of boxes.

Use Cases

• AI Agent Development: Build and deploy autonomous coding agents like Claude Code, Codex, or OpenCode in isolated, reproducible environments with full system access.
• Programmatic Infrastructure: Create, configure, and destroy sandboxes on demand via HTTP API and SDKs (Python, TypeScript) for CI/CD, testing, and scalable automation.
• Remote Development: Access persistent development environments with pre-installed tooling from anywhere — no local setup, no configuration drift.
• Secure User Sandboxing: Spawn isolated, no-env boxes for end users that contain no account secrets and remain fully confined.

Target Audience

Box is built for agent factories, AI infrastructure teams, and developers who need affordable, full-featured Linux sandboxes without managing servers or overpaying for idle resources. Ideal for teams running Claude, Codex, or custom agents at scale who prioritize cost efficiency, programmatic control, and instant environment reproducibility.
