Start with BayEngage — highest vibe code, weakest moat.
Attentive
Building an event-driven SMS workflow app using Node.js, standard cloud databases, and Twilio APIs is straightforward with modern AI code generation. However, replacing Attentive long-term requires navigating 10DLC registration, carrier spam filtering, TCPA legal liability, and deliverability infrastructure that self-hosted code cannot solve alone.

- Visual drag-and-drop journey builder for drip marketing flows.
- Basic subscriber list segmentation based on Shopify purchase history and cart events.
- Triggered transactional and promotional SMS sending logic via third-party APIs.
- A/B split testing for campaign message copy and send times.
- SMS campaign analytics including click-through rate, delivery rate, and attributed revenue metrics.

- Patented two-tap mobile sign-up flows protected against IP litigation.
- Fully managed A2P 10DLC registration and ongoing Campaign Registry compliance monitoring.

BayEngage
The core application logic for triggering automated email/SMS flows and managing customer lists is straightforward to build with modern web stacks. However, deliverability, IP warming, and A2P 10DLC compliance remain hard operational requirements. If you delegate sending infrastructure to raw provider APIs, an AI coding prompt can recreate the app layer in days.
