Start with Growave — highest vibe code, weakest moat.
Growave
Growave bundles loyalty, reviews, wishlists, and UGC galleries into a single $49-$199/mo app. While each individual feature (like a wishlist array or points calculator) is easy to code with AI, managing storefront widget styling, review moderation, photo uploads, and point edge cases across all four modules creates substantial ongoing maintenance overhead.

- Wishlist saved-items logic using local storage or Shopify Metafields
- Points accrual on order payment webhooks

Vouchery
Vouchery is a centralized rules engine for discount validation. Basic coupon validation and point tracking take less than a week to write in Node or Python, but handling atomic concurrency locks during flash sales and dynamic rule combinations requires real effort.
