our call
Start with Fomo — highest vibe code, weakest moat.
Fomo
Fomo listens to order webhooks and renders a simple JavaScript popup toast on your site. Building a custom endpoint to ingest Shopify order webhooks and serve a 50-line JS script takes days, not months. You are paying purely for turn-key UI templates and webhooks.

OptiMonk
