n8n

n8n is a workflow automation platform for technical teams. It's designed for building AI agents and business processes that you can visually trace and control. You get the speed of a visual builder with the flexibility to add custom code whenever you need it. It's a good fit for IT Ops, Sec Ops, and DevOps teams.

The platform combines AI capabilities with process automation. It lets you build complex systems on a visual canvas where you can inspect every step of an agent's reasoning. You can connect to any AI model, whether it's cloud-based or offline, and swap them without rebuilding your workflows.

Key capabilities include:

• Extensive connectivity: Use over 500 pre-built nodes for common applications or connect to any other service with a custom API connection.
• Traceable AI agents: Build multi-agent setups and RAG systems where every decision is visible on the canvas.
• Human-in-the-loop approvals: Enforce structured inputs and combine automated steps with manual approvals to keep people and logic in control of AI actions.
• Code integration: Write JavaScript or Python anywhere in your workflow to handle custom logic that visual builders can't.

n8n's interface shows the inputs and outputs right next to the settings for each step, which simplifies debugging. You can re-run single steps instead of the entire workflow and use real or mocked data to test logic and improve accuracy.

You decide where it runs. Deploy it on your own infrastructure, even in an air-gapped environment, for maximum data protection. A managed cloud version is also available. The platform includes enterprise features for security and governance, such as SSO, version control, audit logs, and role-based access controls.
