Detailed Review of Boxes.dev - AI Code Assistant Software (2026)

What is Boxes.dev?

Give every coding agent its own cloud computer. Bring your Codex or Claude subscription, start agents from Slack and Linear, and manage them from your desktop, phone, or terminal. With your dev environment in the cloud, every surface is a first-class client. boxes . dev gives each agent a whole computer that’s already running your dev environment (a “devbox”), and a way to steer that agent from anywhere. A real Linux box with its own filesystem, port forwarding to localhost, and your dev setup preinstalled. Idle boxes sleep automatically, so parallelism doesn’t turn into runaway costs.
