# Agent sandbox comparison (10 options, 2026)

> A 20 March 2026 comparison of ten agent sandbox tools recommended Membrane (Docker plus eBPF monitoring) for the best security-to-simplicity balance, NVIDIA OpenShell for enterprise policy enforcement on Kubernetes, Agent Safehouse for macOS users and Docker Sandboxes for Docker-in-Docker needs.

Third-party comparison of ten agent sandbox tools with concrete selection advice.

- **Category:** Infrastructure
- **2026 frontier:** Recommendations: Membrane (Docker + eBPF) for balance, NVIDIA OpenShell for Kubernetes policy, Agent Safehouse for macOS, Docker Sandboxes for Docker-in-Docker
- **Credibility:** Useful because it names the trade-off rather than a winner. Two corrections matter: Agent Safehouse and Membrane are real but small projects, and one widely circulated version of this comparison attributes Docker-in-Docker support to E2B — the original recommends Docker Sandboxes for that, while E2B's pitch is managed cloud isolation with no local install.
- **Verification:** Verified
