n8n is an open-source, node-based workflow automation engine built for technical teams who need flexibility beyond typical no-code tools. It supports multi-agent AI orchestration, Retrieval-Augmented Generation (RAG) pipelines, and Model Context Protocol (MCP), and can connect to any AI model — cloud or offline. Developers can inject JavaScript or Python at any node, create custom API integrations, and push workflows through Git-based version control pipelines. The platform provides full observability with audit logs, log streaming to SIEM systems, real-time alerts, and native AI evaluation tooling for iterative optimization.
