Pricing modelPaid Not given
PricingCompute: $0.015 per GiB-hour (approximately $0.000004167 per GiB-second, billed by the second). Storage: $0.02 per GiB-month for retained incremental RootFS data and memory checkpoints. Network ingress and egress currently free. Object-store GET and PUT requests free. New users receive $5 free credi Free: $0/month with 30 calls per month, 3 app numbers + 2 remote numbers. Pro: $9.99/month with 100 calls per month. Scale: $29.99/month with unlimited calls.
Key features
  • Automatic filesystem growth as storage fills
  • Pause compute without losing work or paying compute charges
  • Resume to same environment on demand
  • 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
  • Scoped API keys and team-based access controls
  • On-demand file reads without downloading entire filesystem
  • Private phone numbers for agents
  • Call approval system
  • App and plugin integration
  • Call recording and transcription
  • Cross-device agent connections
  • Number blocking and removal
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
  • First-call approval for security
  • Simple user-controlled access management
  • Data never used for training models
