our call

Start with Evidence — highest vibe code, weakest moat.

CartKit

CartKit is essentially a queueing system listening to storefront checkout webhooks and dispatching emails or SMS via third-party providers. You pay for bundled UI, pre-built copy templates, and handled delivery infrastructure. Building a custom worker with Redis/BullMQ and Twilio/Resend completely replaces its core functionality.

you can rebuild

  • Abandoned cart checkout tracking via storefront webhooks
  • Automated email recovery drips with customizable time delays
  • SMS recovery dispatch with dynamic checkout discount links
  • Web push notification subscriptions and trigger rules
  • Recovered revenue attribution and basic analytics dashboard

what you lose

  • Pre-packaged high-converting email and SMS copy templates
  • Turnkey 10DLC brand and campaign registration management for SMS
  • No-code visual sequence builder for complex conditional logic
  • Built-in unsubscribe and opt-out link handling across channels
  • Zero-maintenance email domain warm-up and deliverability management

real moats

  • 10DLC SMS registration pipeline and carrier trust relationships
  • Pre-warmed sending domain reputation for shared infrastructure
  • Deep platform App Store ecosystem distribution

Evidence

Evidence is a standard social proof notification tool. Its primary function is listening to order webhooks, saving event logs, and outputting them via a small frontend script tag. An AI agent can build a fully functional clone using edge functions and Redis/PostgreSQL in a weekend.

  • Real-time recent purchase notification popups
  • Shopify order webhook payload ingestion and data extraction
  • Visitor location and item name parsing
