n8n

n8n is a workflow automation platform that connects applications, services, and APIs to create automated processes flexibly. Its main differentiator is combining a visual drag-and-drop approach with the ability to incorporate custom logic via code, positioning it between the no-code world and traditional development. A key aspect is its open-source model, allowing organizations to self-host the tool — especially attractive for companies requiring greater data control, regulatory compliance, or advanced customization. A cloud version is also available. The platform works via nodes representing actions, integrations, or data transformations, connected to form workflows automating everything from simple notifications to complex multi-system processes. In the AI context, n8n has evolved to incorporate capabilities for building agents, automating LLM-driven flows, and orchestrating processes using AI APIs. Users can also create custom nodes or integrate custom services.
