Docker Cloud Sandboxes bring laptop AI dev setups to Docker’s cloud

Developers can shift AI agent sandboxes between local machines and Docker’s cloud while keeping their work intact.

Docker has launched Cloud Sandboxes, hosted environments for AI coding agents that bring its local sandbox approach to Docker-managed infrastructure, with hardware-enforced microVM isolation. Developers can shift a sandbox between a laptop and the cloud using `sbx move my-project --to cloud`; Docker says the transfer preserves the filesystem and supports multiple agents running for hours or working in parallel. The company says agents can run for five, ten or 21 hours each, without developers monitoring them. Docker also released Kits under its v3 specification as standard OCI images, usable with image operations such as build and pull and as starting points for more complex Kits. Commenters warned that isolation does not govern an agent’s interactions with services it is allowed to access, and one argued that capability-based controls could offer a better approach.
