What is n8n?
n8n is an open-source workflow automation tool. It connects APIs, apps, and services visually.
Imagine Zapier, but one that you can host yourself, modify the logic, and integrate with literally anything.
How It Works (In Simple Terms)
You build workflows — chains of actions triggered by an event. Each node represents an action: an API call, a function, or a database operation.
Example workflow
- Trigger: New message in Telegram
- Action: Send to Notion
- Action: Post to Twitter
Or imagine this: you create a workflow that saves every birthday from your calendar, and one week before the date it suggests top-trending products on Amazon, then sends them to your Telegram.
Workflows are node-based, so you visually chain nodes together. You can also use custom JavaScript inside nodes for advanced logic.
Why Developers Love It
Developers love automating repetitive tasks so they can spend more time building what matters. Here are the main reasons n8n is popular:
- Open Source: Run it on your own server for full control.
- Custom Code Nodes: Insert JavaScript directly inside the workflow.
- Connects Everything: Hundreds of integrations (GitHub, Notion, Telegram, etc.).
- Webhooks & APIs: Great for connecting backend services and external systems.
- Free: The self-hosted version is free to use.
Real-World Examples
1. Web3 Automation
Create a workflow that triggers when a new on-chain transaction occurs, automatically alert a Discord channel and store the transaction in Google Sheets.
2. Developer Productivity
Get notified when a new GitHub issue is opened. n8n can add it to your Notion board and ping you on Slack.
3. Content Automation
When you publish a new Instagram post, n8n can automatically share it to LinkedIn and Twitter too.
Why It’s a Game-Changer
n8n lets you prototype backends incredibly fast. It’s perfect for indie hackers, startups, and developers. You can even build no-code SaaS MVPs with it.
Conclusion
n8n is open-source automation built for developers. It’s like Zapier, but with freedom, control, and code. It helps you manage workflows, automate tasks, and focus on what truly matters: building.
