Deploy and Host Evolution API Lite on Railway
Evolution API Lite is a lightweight, open-source WhatsApp REST API built on Baileys. Connect a personal WhatsApp account via HTTP endpoints without Meta's Business API approval. Send messages, manage groups, receive webhooks, and automate workflows—all through a simple REST interface. It does not include the manager dashboard — administration is done via REST API only. It omits integrations (Typebot, Chatwoot, OpenAI, S3/Minio) and audio conversion, optimized for microservice environments where performance and simplicity are key.
About Hosting Evolution API Lite
Hosting Evolution API Lite requires a PostgreSQL database for persistence (instances, messages, contacts, chats), Redis for cache and session management, and a persistent volume for WhatsApp instance 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.
