n8n is an extensible open-source automation platform that helps you build AI-driven workflows without being locked into a single vendor. It combines a visual node-based editor with the option to code custom logic, giving teams full control over how large language models (LLMs) and data sources interact.
Key points about n8n:
Works with hundreds of integrations, LLMs, vector stores and REST APIs via a drag-and-drop node editor
Lets AI agents make decisions, then adds guardrails with human-in-the-loop steps and explicit decision rules
Blends no-code and code – branch, loop and adapt with JavaScript or Python for advanced logic
Built-in debugging with data replay, inline logs and visual traces for every agent interaction
Self-host or cloud-hosted with role-based controls and cost-saving triggers to keep budgets in check
n8n lets technical teams ship agentic workflows quickly while maintaining control over data, execution and costs.
