CheckOutMyBackend: Production-ready AI starter kits for React & iOS

Hi Product Hunt! 👋 I’m Cody, the maker behind CheckOutMyBackend. Like many of you, I love building AI apps, but I absolutely dread the initial backend configuration. Writing the exact same boilerplate for authentication, state management, and API text streaming over and over was completely killing my momentum. I decided to stop reinventing the wheel and extract my cleanest, most secure setups into reusable templates. Today, I'm launching the site with two production-ready stacks: ⚛️ The Web Stack (React + Supabase): A React/Vite frontend pre-configured with a custom Deno Edge Function. It uses Server-Sent Events (SSE) to stream OpenAI text cleanly while safely hiding your API keys. It even includes pre-built Stripe checkouts. 📱 The Mobile Stack (Native SwiftUI + Supabase): A fully functional iOS e-commerce client pre-wired with mobile auth, visible loading indicators, and a secure OpenAI Vision pipeline. My goal is to help you skip the setup headaches and actually ship your app this weekend. I’d love to hear your feedback, and I’m hanging out in the comments all day to answer any technical questions about the Deno architecture, Supabase integration, or React state locks!
