How does pricing compare?

boat: Free Trial, Paid. Per-second billing with a $20/month minimum. The default 4 vCPU / 8 GB sandbox lists at $0.036/h, with smaller (2 vCPU / 4 GB) and larger (8 vCPU / 16 GB, 16 vCPU / 32 GB) sizes available. A 7-day free trial with a card provides 25 compute hours, and stopped sandboxes incur no compute charge while the disk is retained for at least 14 days. Metaflow: Free. Metaflow is free and open source. You install the Python package at no cost and pay only for the cloud infrastructure you run it on — for example your own AWS, Azure, or Google Cloud account, or an on-premise Kubernetes cluster. A browser-based Metaflow Sandbox is available to explore it without setting anything up.

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
