Devin

  • Cannot handle extremely difficult tasks reliably; success rate decreases with task complexity
  • Requires clear, well-scoped task descriptions; ambiguous requirements reduce effectiveness

  • Mock servers are capped at 1,000 requests a month on free, then $10 per 25,000
  • Role-based access control requires Pro at $12 per user per month
  • SSO, SCIM and vault integrations are Enterprise only at $45 per user per month
  • Working without an account is limited to the local-only Scratch Pad
