Today we're introducing Cloud Sandboxes: same microVM isolation as Docker Sandboxes on your laptop, same CLI, always-on Docker-managed compute.
Close your laptop. Keep the agent running. Move between local and cloud with one command. $250 credit for new accounts:
The isolation question for AI agents is getting more specific. Not 'is it sandboxed?' but 'what exactly does the boundary hold, and what can get past it?'
Sandbox Review on how to answer that, and what major coding agents are actually doing about isolation in production today:
An agent that breaks something isn't broken. It's doing exactly what it was built to do, just not what you intended.
Docker鈥檚 Eric Jia and @srinisekaran on the five main agent security risks, why traditional app security wasn't built for them, and the incidents behind each one:
The 2026 Stack Overflow survey is out. We鈥檙e honored Docker remains the most used and most desired cloud dev tool.
It also shows trust is the biggest gap in the agentic era: just 7% of developers trust AI for important work decisions. Docker CMO Terri Avnaim on extending trust
Agents that can edit files and run commands can also game their own evals.
Harbor + Docker Sandboxes fix that: every eval task runs in an isolated microVM, with network policies for fair, reproducible runs.
