our call

Start with LimeChat — highest vibe code, weakest moat.

LimeChat

Building a custom LLM agent that connects to Shopify's GraphQL API for order tracking takes a few days. Replicating the Meta WhatsApp Cloud API webhooks, template approval flows, 24-hour service messaging windows, and human agent inbox UI takes several months.

you can rebuild

  • Shopify order status lookup via chat
  • Product catalog Q&A using RAG
  • Automated tracking URL lookup and delivery status
  • Basic lead capture and opt-in handling
  • Simple discount code disbursement over chat

what you lose

  • Managed Meta WhatsApp Business Partner (BSP) setup and phone number migration
  • Pre-built multi-agent human support inbox with real-time assignment and SLAs
  • Meta-compliant WhatsApp template submission and status sync UI
  • Out-of-the-box WhatsApp broadcast campaign scheduler and rate-limiter
  • Native Shopify checkout conversion tracking for WhatsApp campaigns

real moats

  • Meta WhatsApp Business API infrastructure management and template submission tooling
  • Deep webhooks integration with real-time state sync across Shopify and WhatsApp
  • Turnkey multi-agent live chat desktop built for high-throughput support teams

Trengo

Building a simple UI for customer messages is straightforward, but maintaining Meta Business API connections, email parsing edge cases, and reliable WebSocket state for multiple support agents is complex. Self-hosting Chatwoot or paying Trengo is vastly superior to writing custom inbox plumbing.

you can rebuild

  • Unified agent UI with real-time message feeds
  • Shopify customer contextual sidebar (orders, dynamic links)
  • Rule-based routing and agent assignments
  • Basic auto-replies and template response management
  • Ticket tagging, internal notes, and status management

what you lose

  • Turnkey Meta WhatsApp Business Cloud API integration and BSP infrastructure
  • Pre-built Instagram Direct and Facebook Messenger API webhooks
  • No-code flowbot builder with complex decision trees
  • Voice/VoIP integrations directly within the shared inbox
  • Out-of-the-box SLA management and agent productivity reporting

real moats

  • Meta Business Partner ecosystem navigation and WhatsApp template registration pipelines
  • Ingestion pipeline stability across high-volume webhook streams (Meta, SendGrid, Twilio)
  • Cross-channel user identity resolution and contact deduplication logic
