Docker's microVM sandboxes for running AI coding agents isolated from your host

Bedingt

Docker Sandboxes is a free way to let coding agents such as Claude Code, Codex or Gemini run with full sudo inside a microVM with its own kernel, Docker Engine, deny-by-default networking and proxy-injected credentials. Conditional on patching and mount discipline: releases from 0.28.0 until the 0.42.0 fix carry a critical macOS host-file escape, and the default mount is read-write, so the agent edits your working tree in place. Right for developers running agents unattended.

KI-gestützt

Isolation runtime that hosts third-party coding agents in microVMs; it runs no model itself.

Ist es das Richtige für dich?

Gut für

  • Giving an agent full sudo and its own Docker Engine without exposing the host kernel
  • Keeping API keys out of the agent: the host proxy injects auth headers and raw credentials never enter the VM
  • Reviewing agent work before it touches your tree: `--clone` mounts the repo read-only and the agent works on a private clone
  • Running many agents one way: eleven are supported, including Claude Code, Codex, Copilot, Cursor, Devin, Gemini and OpenCode

Nicht geeignet für

  • Unpatched installs: versions 0.28.0 to before 0.42.0 on macOS let guest code read or modify arbitrary host files
  • Protecting the working tree under the default mount: changes to Git hooks and build scripts reach the host immediately
  • Isolating local MCP servers, which run on the host with host permissions
  • Intel Macs, Windows 10 or Windows on Arm, or Ubuntu before 24.04: it needs Apple silicon on macOS 14+, Windows 11 on a 64-bit Intel or AMD processor, or Ubuntu 24.04+ with KVM

    Overview page now states cloud sandboxes use a pay-as-you-go subscription with model-provider charges separate; added a Cloud sandboxes tier (rate not published on the page). sbx CLI and local compute free including commercial use, and org governance on a separate paid subscription, unchanged.
