our call
Start with Inveterate — 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.
