Evolution API is a production-grade, multi-tenant WhatsApp API gateway built with Node.js, TypeScript, and Express. It manages independent WhatsApp instances via Baileys (WhatsApp Web), Meta Business API, and its own Evolution API channel, providing REST endpoints for messaging, chat management, groups, labels, and media. The system integrates deeply with chatbot platforms (Typebot, OpenAI, Dify, Flowise, N8N, EvoAI, EvolutionBot) and event systems (Webhook, WebSocket, RabbitMQ, SQS, NATS, Kafka, Pusher), and includes storage via S3/MinIO and CRM sync with Chatwoot. The architecture follows a modular controller-service pattern with Prisma ORM (supporting MySQL and PostgreSQL), Redis caching, and centralized configuration. It is actively maintained with frequent updates, extensive migrations, and CI/CD pipelines.
This is the umbrella monorepo for Evo CRM Community, an open-source AI-powered customer support platform. The repository itself does not contain application source code; it orchestrates seven independent microservices (auth, CRM, frontend, AI processor, core service, bot runtime, and event flow) via Git submodules and Docker Compose/Swarm configurations. The primary function of this repo is to provide a single entry point for cloning, building, seeding, and deploying the full stack. It includes a nginx API gateway for path-based routing to backend services, CI/CD workflows for building and publishing Docker images, migration version collision guards, and extensive release documentation. The actual business logic, AI agent execution, conversation management, and user interface reside in the submodules.
