About

Sandbox0 offers managed sandbox infrastructure specifically designed for long-running AI agents. It provides isolated execution environments with a durable writable RootFS, enabling incremental filesystem checkpoints and on-demand resume. This ensures that dependencies, repositories, and files persist across different runtime generations, optimizing for cost-efficiency by only charging for compute when the sandbox is running.
