Our verdict on microsandbox
microsandbox runs untrusted code, generated programs, agents, plugins, and other workloads inside hardware-isolated microVMs, with a separate kernel for each sandbox. It is aimed at developers, startup teams, and larger organizations that need isolated execution with configurable CPU, memory, disk, and network policies. OCI image-based creation, a CLI, and SDKs for Rust, TypeScript/Node, Python, and Go support both application integration and operational workflows across Windows, macOS, Linux, and the API.
Pricing is structured for individual development through larger deployments. The Free plan costs $0 per month and includes a hard-capped monthly pool, up to 3 total sandboxes, and 1 GiB of total durable storage. Builder costs $49 per month and is designed for an individual developer building a production app, with 1,000 ephemeral running sandboxes and 50 persistent running sandboxes. Teams costs $299 per month for a startup team scaling an agent application, with 25,000 ephemeral running and 500 persistent running. Enterprise uses a custom agreement for organizations evaluating a committed or BYOC model.
The standout fit is breadth of execution and control: microsandbox supports local execution, a private-beta cloud, and bring-your-own-cloud or metal deployments. Network egress can use allowlists or be disabled, while private, host-local, link-local, and metadata destinations are blocked. Stopped sandbox disk state can be saved as snapshots, adding persistence without changing the isolated execution model. Choose microsandbox when flexible deployment, SDK coverage, concurrency, and workload isolation matter. Smaller experiments may find the Free plan restrictive, while teams requiring immediate public cloud access should consider the private-beta availability before choosing it.
