N8N  

What is n8n and how does it work?

πŸš€ What is n8n?

n8n (pronounced “n-eight-n”) is an open-source workflow automation tool that allows you to connect different apps, services, and systems — all without writing complex code. Think of it as a visual tool that helps you build workflows by dragging and dropping blocks (called nodes) that represent steps in a process.

Unlike tools like Zapier or Make, n8n gives you complete control over how data flows between applications. It’s built for developers and power users who want flexibility and the ability to self-host their automation system.

πŸ’‘ Why Use n8n?

Here are some of the biggest reasons people love using n8n:

  • βœ… Open Source & Free
    You can self-host it for free, with no per-task limits.

  • πŸ” Privacy-Friendly
    Since you can run it on your own server, your data stays with you.

  • πŸ› οΈ Highly Flexible
    You can write custom JavaScript functions or even build your own nodes.

  • 🌐 Connects to Hundreds of Apps
    Out-of-the-box support for popular tools like Slack, Google Sheets, Airtable, MySQL, GitHub, and more.

  • 🧱 Visual Workflow Builder
    Easily build workflows using a drag-and-drop interface.

πŸ”„ How Does n8n Work?

n8n uses a node-based architecture to define workflows. A workflow is a series of nodes connected in sequence to perform a task.

πŸ“Œ Key Concepts

  • Workflow: A sequence of steps to automate a task.
  • Node: A single step in the workflow. It could be an API call, a webhook, or a simple logic operation.
  • Trigger: A special type of node that starts the workflow (e.g., a webhook or time schedule).
  • Execution: When a workflow runs.

🧩 Example Use Case

Let’s say you want to:

  • Get notified in Slack whenever someone fills out a Google Form.
  • Save the form data to Airtable.
  • Send an email confirmation to the user.

With n8n, you can:

  • Use a Google Sheets trigger to start the workflow.
  • Add a Slack node to send a message.
  • Add an Airtable node to save data.
  • Add an Email node to send confirmation.

All visually — no coding needed!

πŸ› οΈ Hosting Options

  • Self-Hosted (Free): Run it on your server, cloud VM, or Docker.
  • n8n Cloud: Managed version offered by the n8n team (paid).

For most developers and startups, self-hosting is a great way to save costs and maintain control.

🧠 What Can You Automate With n8n?

  • Social media posts across platforms
  • CRM updates (like HubSpot, Salesforce)
  • Data syncing between apps (like Google Sheets ↔ Notion)
  • Email marketing sequences
  • Order processing from e-commerce platforms
  • Alerts and monitoring
  • AI-powered workflows using OpenAI or Hugging Face
