  • Public sandboxes are visible to others by default, which is not ideal for proprietary code.

Refact

  • Requires configuration for optimal performance
  • On-premise deployment adds operational complexity
  • Free tier limited by daily agent request quota
  • Coin system adds complexity to cost calculation
