our call
Start with CartFox — highest vibe code, weakest moat.
CartFox
CartFox's core functionality is catching store webhooks, pushing them into a delayed job queue, and dispatching text messages via an SMS carrier API. Building this logic requires a basic backend, Redis queue, and Twilio integration. The main friction in self-building is telecommunication regulatory overhead like 10DLC registration, not code.

- Delayed message sequence queue (e.g., 30-min, 24-hour triggers)
- Order confirmation and shipping tracking update SMS dispatches
- Dynamic discount link generation and URL shortening

what you lose
- Zero-setup bundled telecommunication routing

- Visual drag-and-drop SMS flow builder UI
- Instant single-click integration via Shopify App Store
- Automated carrier bounce and bad-number validation filters
