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.

- Recent order notification toast rendering
- Shopify order webhook receiver and event queuing
- Geo-location display based on order IP or city
- Customizable popup styling, position, and timing controls
- Impression logging and click-through analytics
what you lose
