FlutFast
A Flutter starter kit with Firebase auth, in-app purchases, and OpenAI wired in

- Best for
- Solo Flutter developers building an app with in-app purchases and AI features who want Firebase and OpenAI already integrated.
- Skip if
- You want a free/open-source starter, or you're not building for Flutter/mobile.
FlutFast is a paid Flutter boilerplate with 50+ UI components, Firebase authentication and Firestore, and an optional TypeScript/Node.js backend for securing API keys. It includes in-app purchases and paywalls via RevenueCat, OpenAI (GPT-4/Vision) integration, SendGrid email automation, and Mixpanel analytics, with GitHub Actions CI/CD.

- Tiered pricing lets you buy just what you need, starting at $60
- GitHub Actions CI/CD included
