n8n

n8n (pronounced "nodemation") is an open-source workflow automation platform that enables users to connect apps, APIs, and AI services through a visual node-based interface. Founded in 2019 by Jan Oberhauser, the company has built a large community of developers and automation enthusiasts who use n8n to build complex, AI-powered workflows.

n8n provides over 400 integrations and supports custom code nodes (JavaScript, Python) for unlimited extensibility. In the AI era, n8n has become a popular platform for building AI agent workflows — connecting LLMs to databases, APIs, web scrapers, and business tools to create sophisticated automation pipelines. n8n's AI nodes support OpenAI, Anthropic, Google, and other model providers, with built-in support for RAG, memory, and tool use.

n8n's open-source model (fair-code license with self-hosting option) differentiates it from proprietary alternatives like Zapier and Make. The ability to self-host gives enterprises full control over data and workflow execution — particularly important for AI workflows that process sensitive information. n8n's combination of visual design, code flexibility, and AI-native features has made it the preferred automation platform for technical teams building production AI systems.
