box

About box

box is a cloud computing service that spins up full Ubuntu virtual machines on demand for AI agents. A single terminal command creates a VM with admin rights, SSH access, and a desktop environment in about two seconds. The tool targets developers building agentic platforms and software factories who need scalable, low-cost compute for long-running workloads.

Review

box enters a space crowded with containers and sandboxes, but it focuses on full VMs rather than ephemeral environments. The interface is a single CLI command, and the pricing is set at $0.036 per hour. Self-serve concurrency goes up to 1,000 boxes, with same-day support from the founders for larger requests.

Key Features

• Run box new in a terminal to get an Ubuntu VM with admin rights, desktop, and SSH access in roughly 2 seconds.
• Built-in snapshotting supports stopping, resuming, and forking a VM's state, so agent workflows can pause and pick up where they left off.
• Self-serve scaling allows up to 1,000 concurrent boxes, with the team offering same-day support for higher limits.
• Templates let you preconfigure boxes with project-specific tooling, avoiding repeated setup.
• Pricing at $0.036 per hour, which the team states is roughly 10 times less than alternatives like E2B, Daytona, and Modal.

Pricing and Value

box charges $0.036 per hour per VM. The company claims this is about 10x cheaper than competing services such as E2B, Daytona, and Modal. No free tier or volume discounts are detailed on the page. The value centers on running many agents or long-running tasks without the cost scaling linearly with container-based alternatives.

Pros

• VMs provision in seconds with a single command.
• Full admin rights and SSH access, not limited to container runtimes.
• Snapshot and fork capabilities let you save and resume agent state.
• Concurrency limit of 1,000 boxes with self-serve management.
• Founders provide same-day support, even for larger deployment requests.

Cons

• The service is two months old, so its production track record is limited.
• Isolation specifics between VMs on the same host are not publicly detailed, which may matter for security-conscious workloads.
• Not well suited for teams that need managed enterprise compliance, audited security certifications, or pre-built reporting.

box fits developers and small teams who need cheap, stateful compute for agentic platforms and can handle infrastructure details themselves. It's a practical option for AI coding agents that install system dependencies or spawn nested processes. Teams requiring strict isolation guarantees or enterprise governance should evaluate the product as it matures.
