Nasca

Nasca is the RevenueCat for AI apps. We handle per-user limits, credit top-ups, upgrade prompts, and Stripe Connect in 10 lines of code. When a user hits their limit, Nasca shows a conversion-optimised upgrade prompt instead of a dead end. They buy credits or upgrade a plan, pay through your Stripe account, and continue immediately. Building this yourself takes weeks. Nasca takes minutes. Free up to 100 users. 2% only when users convert.
