Pause idle E2B sandboxes automatically
Free active capacity while keeping unfinished work ready to resume.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Pause Sandbox
Tool to pause a running E2B sandbox preserving its filesystem and memory state. Use when you need to temporarily suspend a sandbox while maintaining its state for later resumption. Takes approximately 4 seconds per 1 GiB of RAM to pause. Paused sandboxes can be stored for up to 30 days.
Why this helps
Idle sandboxes keep running because nobody has time to inspect and pause them.
- Reduces unnecessary runtime
- Preserves unfinished state
- Creates a repeatable cleanup habit
