What Is n8n
n8n is an open-source workflow automation platform. It lets you connect APIs, databases, and AI models in a visual node-based editor, and it has become a popular choice for building LLM-powered agents and pipelines without writing a full application.
AI Workflows
n8n ships native AI nodes with support for major LLM providers — including Claude and Gemini — plus vector store integrations for retrieval-augmented generation. There is no separate AI pricing tier: you pay your normal n8n cost plus whatever LLM API fees you incur.
Pricing
The self-hosted Community Edition is free with unlimited executions. n8n Cloud is execution-based, starting at the Starter tier and scaling up through Pro and Business plans, with an Enterprise option and a discounted Start-up plan for small companies.
Who It’s For
n8n suits engineers and technical founders who want to automate processes and orchestrate AI agents visually, and who value the option to self-host for cost control and data ownership.
