How to read this: Paid plans remove prompt limits so teams can iterate fast without inflated credit pricing. You still pay model providers (Claude/Gemini/etc.) directly using your own keys, so you keep full cost control. The Free plan is perfect to validate the workflow, but exporting the full codebase and commercial shipping are reserved for paid plans.
