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.

you can rebuild

  • 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

  • Pre-built integrations with third-party platforms like Mailchimp or Trustpilot
  • Out-of-the-box visual CSS customization UI
  • Native A/B testing engine for popup variations
  • Complex device-level and URL-matching targeting rules
  • Managed global CDN handling high impression throughput

real moats

  • Turnkey pre-built integrations library across 100+ SaaS platforms
  • Zero-code installation for non-technical store owners
  • Managed edge infrastructure optimized for millions of low-latency requests

  • Back-in-stock and price-drop automated push alerts
  • Subscriber opt-in prompt customizer widget
  • Broadcast campaign creation and scheduling dashboard
  • Click-through rate and revenue conversion reporting

what you lose

  • Pre-built Smart Flyout and custom delayed opt-in prompt UI presets
  • Managed FCM/APNS payload delivery handling across browser versions
  • Out-of-the-box Shopify app store integration and script injection
  • Built-in campaign benchmark analytics across merchant networks
  • Turnkey subscriber segmentation engine by purchase history

real moats

  • VAPID key lock-in tied to push endpoints and browser subscriptions
  • Native Shopify app store distribution and zero-code installation
  • Historical subscriber push token database tied to specific domains
