Deploy and Host WhatsApp Business Platform on Railway

A self-hosted AI WhatsApp messaging platform built on Twilio's WhatsApp API. Send bulk campaigns, manage contacts, create message templates, and track delivery — all from a clean React dashboard. Includes an in-app setup wizard so non-technical users can connect Twilio without touching config files.

About Hosting WhatsApp Business Platform

Hosting WhatsApp Business Platform requires a Node.js backend (Express + Prisma), a React dashboard served via Nginx, a PostgreSQL database for contacts/campaigns/templates, and a Redis instance for job queues and session management. The backend exposes a REST API and handles Twilio webhooks for message status callbacks. The dashboard is a single-page app that communicates with the backend API. All Twilio credentials (Account SID, Auth Token, WhatsApp number) are stored in the database and configurable through the UI — no environment variable editing needed after initial deploy. File uploads are persisted on the backend container's volume.

Common Use Cases

1. Bulk WhatsApp campaign broadcasting to customer lists
2. Transactional WhatsApp notifications (order updates, appointment reminders, OTPs)
3. Small business customer engagement without a per-seat SaaS subscription fee
