About

Sandbox0 is a managed runtime for long-running AI agents. Run code and install tools in isolated cloud computers while preserving software, configuration, and files across successful checkpoints. Pause compute between tasks and resume the same environment on demand. Growth-enabled templates expand the writable root filesystem online. APIs, SDKs, and the s0 CLI support sandbox lifecycle, commands, files, templates, and snapshots. Default pause and resume retain files and start fresh processes. The runtime is closed source; SDKs and CLI are open source.
