A Beginner’s Guide to N8N: Automating Your Business Processes

What is n8n?

n8n is an open-source workflow automation tool that allows users to automate repetitive tasks by connecting various applications and services without requiring sophisticated programming skills. Its name is a play on “n8n” which sounds like “and then”, indicating the automated process of task chaining. With a visually intuitive interface, n8n simplifies the creation, execution, and management of workflows.

Key Features of n8n

Open Source

n8n is fully open-source, providing users with the flexibility to customize and self-host their automation workflows. This means they can modify the code to fit their specific business needs, thereby ensuring greater control over their data.

Extensive Integrations

With over 200 pre-built integrations, n8n seamlessly connects to a wide array of third-party applications, including popular platforms like Google Sheets, Slack, HubSpot, and more. This diverse ecosystem allows businesses to automate workflows between different applications effortlessly.
