Deploy and Host Evolution API on Railway

Evolution API is an open-source WhatsApp REST API built on Baileys. Connect any WhatsApp account via HTTP endpoints without Meta's Business API approval. Send messages, manage groups, receive webhooks, and automate workflows through a simple REST interface.

About Hosting Evolution API

Hosting Evolution API requires three core services: a PostgreSQL database for persistence of instances, messages, contacts and chats; Redis for cache and session management; and a persistent volume mounted at /evolution/instances for WhatsApp authentication data. The API listens on port 8080 and exposes REST endpoints for instance creation, QR code connection, messaging, and webhook configuration. Railway provisions all services and handles networking, SSL, and scaling automatically.
