About

Modal Sandboxes are created from Python code to run agent-generated or untrusted code in isolated, disposable environments. Each sandbox can use its own image, filesystems can be snapshotted and resumed later, and domain egress can be locked down. Sandboxes scale to large numbers of parallel rollouts.

Use cases: cloud-management
