Boxes.dev is a platform that allows developers to host coding agents, such as Claude Code and Codex, on cloud-based virtual machines rather than local hardware. The service enables agents to operate in parallel, allowing tasks to continue running even after a user closes their laptop or goes offline. Each agent is assigned its own Linux-based environment (a “fork”), providing a complete setup that includes its own filesystem, database state, and active services. This architecture allows developers to manage multiple agents simultaneously, perform manual testing on localhost via port forwarding, and steer tasks directly from desktop, mobile, or CLI interfaces.

To begin, users select a local codebase folder for the system to scan and replicate in a cloud devbox. Once initialized, the platform uses snapshots of the primary environment to spin up isolated machines for different tasks. Users can schedule automated jobs, such as weekly dependency audits, or trigger agent workflows via Slack and Linear integrations. The system is designed to integrate with existing developer subscriptions for coding agents rather than selling tokens directly.

Pricing is consumption-based, measured by "box-hours," where one box-hour equals one 4 vCPU / 8 GiB instance awake for one hour. The platform offers a free trial tier including 10 box-hours, a $19 per month Starter tier with 40 included hours, and a $99 per month Pro tier providing 250 hours. A dedicated Teams tier is also available for organizational use, featuring additional security controls such as SSO, audit logs, and role-based access control. The service is compatible with macOS 12+, iOS, Android, and CLI tools, with all idle forks automatically entering sleep mode to avoid unnecessary usage costs.
