our call
Start with Glow Loyalty — 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.
