Start with Charles — 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.
