About
Sandbox0 is a managed sandbox runtime for long-running AI agents. It provides isolated code execution and a durable writable RootFS, so committed dependencies, repositories, files and work products can survive runtime generations.
Incremental filesystem checkpoints and on-demand resume help separate stored workspace state from active compute. Default pause/resume saves filesystem state and starts fresh processes; existing external connections must reconnect.
Developers can manage sandbox lifecycles, run commands, work with files, use stateful REPL contexts and connect through SSH. Python, JavaScript/TypeScript and Go SDKs and the s0 CLI support integration into agent workflows.
The managed runtime is closed source; the SDKs and CLI are open source. See the official documentation and pricing for current availability and usage costs: https://sandbox0.ai/docs/sandbox and https://sandbox0.ai/ .
