Alibaba OpenSandbox offers a powerful, fully self-hostable execution layer for AI agents, but teams must actively configure secure runtimes like gVisor instead of relying on the default Docker setup for untrusted code.
OpenSandbox provides a unified execution layer and API for AI agents across multiple programming languages.
The tool supports multiple isolation layers, including standard Docker for local development and Kubernetes with gVisor or Kata Containers for production.
Released in March 2026 under the open-source Apache 2.0 license, allowing for full self-hosting and zero vendor lock-in.
It handles stateful code execution via an injected Go-based execution daemon and streaming through Server-Sent Events.
