OpenSandbox and Bandsox
OpenSandbox is a mature, production-ready sandbox platform that Bandsox could potentially use as an underlying execution environment, making them complements rather than direct competitors.
About OpenSandbox
alibaba/OpenSandbox
OpenSandbox is a general-purpose sandbox platform for AI applications, offering multi-language SDKs, unified sandbox APIs, and Docker/Kubernetes runtimes for scenarios like Coding Agents, GUI Agents, Agent Evaluation, AI Code Execution, and RL Training.
Supports strong workload isolation through secure container runtimes (gVisor, Kata Containers, Firecracker) and implements unified network policies with ingress gateway routing plus per-sandbox egress controls. The platform provides built-in Command, Filesystem, and Code Interpreter implementations with lifecycle management across Docker and high-performance Kubernetes runtimes, enabling seamless scaling from local development to distributed scheduling.
About Bandsox
HACKE-RC/Bandsox
Sanboxes for AI agents and humans
Leverages Firecracker microVMs with millisecond boot times, bootstrapping from Docker images and executing Python code directly within isolated environments. Provides vsock-based file transfer (100-10,000x faster than serial) with automatic fallback, plus snapshot/restore capabilities for instant VM cloning. Includes a Python API, CLI, and FastAPI-powered web dashboard for VM lifecycle management, file browsing, and terminal access.
