boat is a cloud sandbox platform providing persistent Ubuntu virtual machines designed for AI agents and programmatic workflows. Each sandbox includes SSH and SCP access, Docker support, a dedicated IP address, a 60fps virtual desktop, and fast disk-level forking from snapshots. Pre-installed tools include Docker, VS Code, Chrome, GitHub CLI, Rust, Node.js, and Bun, making sandboxes immediately usable without setup. boat supports agents such as Claude Code, Codex, and OpenCode, and offers a Python and TypeScript SDK alongside an HTTP API and CLI. Pricing starts at $20 per month after a 7-day free trial, with per-second billing and no charges when sandboxes are stopped.
