n8n

n8n is an open-source workflow automation platform that enables users to connect applications, automate processes, and build AI-powered workflows through a visual, node-based interface. Often described as a self-hostable alternative to Zapier, n8n combines traditional automation with AI agent capabilities.

n8n's AI features include native LLM integration, AI agent nodes that can reason about tasks and use tools, RAG pipelines for knowledge-grounded responses, and support for building custom AI workflows without code. The platform supports over 400 integrations and can be self-hosted for data privacy and compliance requirements.

In the agent orchestration layer, n8n represents the democratization of AI agent building — making it possible for non-developers to create sophisticated AI-powered automations that connect to real-world business tools and data.
