Why unsandbox?

Freeze / Unfreeze

Pause containers when idle, wake them instantly on demand. Pay only for active compute time.

Persistent Services

Deploy web apps with automatic Let's Encrypt HTTPS. Custom domains, port mapping, and wake-on-request.

Container Snapshots

Save container state and restore later. Clone snapshots to new sessions or services.

Deep Freeze

Services hibernate when keys expire. Wake them years later - data preserved indefinitely.

Use Cases
