our call
Start with Growave — highest vibe code, weakest moat.
Gatsby
The core job—listening to Instagram webhooks, grabbing emails from DMs, and updating Klaviyo/Shopify—is trivial backend code. However, navigating Meta's App Review process, staying compliant with Messenger policies, and managing rate limits during viral bursts make running custom infrastructure a chore.

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.
