boat

Persistent Ubuntu cloud VMs built for AI agent factories

Persistent full Linux VMs

Each sandbox is a complete Ubuntu machine with systemd, Docker, databases, and cron, so anything that runs on Linux runs here.

Fast snapshot forking

Clone a configured sandbox from a disk snapshot in seconds to launch large fleets of identical parallel agents.

SSH, SCP, and virtual desktop

Connect over SSH and SCP or open a 60fps virtual desktop and browser to inspect web apps, IDEs, and 3D scenes.

API, CLI, and SDKs

Drive everything programmatically through the boat CLI (with --json output), an HTTP API, or Python and TypeScript SDKs.

Strengths & Pros

+Full Ubuntu VMs rather than restricted containers, with Docker and systemd included
+Very fast disk-level forking makes large parallel agent runs affordable
+Transparent per-second pricing with no compute charge while stopped
