Notes

  • Transfer has a rolling 7-day quota and is throttled when exceeded. Connections and transfer are not measured by current inputs
  • Backups and automatic scaling are unavailable on Free
  • No Free-specific commercial-use permission or restriction was confirmed in this review. Descriptions aimed at learning and testing are not treated as a prohibition
