- The page distinguishes frozen after two idle seconds from asleep 45 seconds later, where memory is sealed to disk and waiting is free.
Field notes
The homepage says any command, file call, port request, SSH byte, or inbox webhook can wake a sandbox. Its example keeps an interactive Python session intact after 2 days and 4 hours asleep, and the page reports a 47 ms wake with three processes intact. For risky changes, it describes checkpointing a running sandbox, comparing states, restoring, or branching from a checkpoint or live machine.
