Access files while paused without waking compute
Public HTTP services with auto-resume capability
Command-line interface (s0 CLI) for agent-native workflows
Incremental checkpoints to avoid full filesystem copies

1,000 automation runs per month on free plan
Full data export available anytime
Sealed backups every night with secure key storage
What makes it different
Persistent filesystem across pause/resume without duplicating data
Pay only for compute time used; paused sandboxes have zero compute charges
Automatic filesystem growth so agents can install and persist unlimited tools
Same API for both human users and AI agents
Works with any agent that speaks MCP protocol, not vendor-locked to one tool
Integrates work tracking and financial management in one place agents automatically read
Full audit trail and undo capability for every change
