Our review
Pros	Firecracker microVM isolation with a dedicated kernel per sandbox Configurable outbound networking, persistent state, and session controls SDK, REST API, CLI, Dockerfile templates, and BYOC deployment	Separate kernel and Docker daemon for each sandbox Network, filesystem, credential, and workspace isolation controls Free CLI with support for major coding agents
Cons	Pro usage is billed by the second beyond the monthly plan Hobby sessions are limited to 1 hour and 20 concurrent sandboxes Advanced observability and signed webhooks are enterprise features	Organization governance is a separate paid subscription Cloud persistent volumes are distinct from local sandbox environments Focused on agent workspaces rather than general-purpose sandboxing
