Key Features of n8n

Open Source Nature

Being open-source means that n8n’s source code is publicly available, enabling developers to contribute to its development. This also allows organizations to customize the tool according to their specific needs. The open-source aspect ensures community support and the continuous improvement of features based on user feedback.

Visual Workflow Builder

n8n’s visual workflow builder offers a seamless experience for users. The drag-and-drop interface simplifies the design process, allowing users to create complex workflows effortlessly. This feature also provides real-time visualization of the workflow, enabling better understanding and management of processes.

Self-Hosting Capability

n8n can be installed on any infrastructure, providing flexibility and control over data management.
