n8n is a free, open-source automation platform that lets you connect over 1,000 apps, build custom workflows, and use AI to streamline tasks across your business. You don’t need a license, you get full control over your data, and you can customize everything. The only catch? You need to self-host it.

In this guide, we’ll show you exactly how to set up n8n for AI automation using Hostinger, one of the easiest and cheapest ways to get started. I’ll also walk you through how to create your first workflow, add AI tools, and automate real tasks step by step. Let’s get into it.

 

What Is n8n and Why Should You Use It?

n8n stands for “node-to-node,” and it works a lot like Zapier or Make.com but with zero monthly fees, more flexibility, and full customization. You can build powerful AI workflows that trigger actions based on anything: new leads, website visits, emails, spreadsheets—you name it.

You can connect OpenAI, Google Sheets, Slack, Notion, Gmail, Airtable, Discord, webhooks, and more.

If you’re running a startup or managing tasks solo, n8n is perfect for automating things like:

• AI-generated email replies
• Lead capture from forms
• Social media scheduling
• Auto-sending proposals or follow-ups
• Client onboarding workflows

You can build all of this without writing code. And since it’s self-hosted, you’re not locked into a platform that limits how much data you process or how many workflows you can build.

   Why We Recommend It

   Hostinger’s n8n VPS hosting offers an efficient solution for automating tasks and integrating various applications. With n8n pre-installed, users can quickly set up workflows, enhancing productivity without the need for extensive technical knowledge.​

   Pros & Cons

   • Easy setup with n8n pre-installed on the VPS
   • Flexible resource allocation to match your automation requirements
   • Cost-effective compared to managed automation services

   • Requires basic server management skills for optimal use
   • Advanced features may necessitate additional configuration

2. Choose any VPS plan (even the lowest-tier plan works for n8n)
3. During setup, select the n8n pre-configured template
4. Launch your server and wait a few minutes for setup
5. You’ll get login credentials to access your n8n dashboard

Once it’s live, you can go straight to your custom n8n URL and start building.

 

Step 2: Access the n8n Dashboard

After you install n8n, you’ll get access to your own dashboard. This is where you build and manage all your workflows.

Here’s what to do next:

• Log in using the credentials Hostinger provided
• Bookmark your dashboard link (you’ll use it a lot)
• Click “Create New Workflow” to get started

You’ll see a visual canvas where you can drag and drop different nodes. Each node represents an action, like sending an email or calling an AI API.

 

Step 3: Build Your First AI Automation Workflow

Let’s say you want to build a simple AI email responder. Here’s a basic flow you can set up:

1. Trigger Node – Start with a webhook or email trigger
2. OpenAI Node – Connect to GPT-4 using your API key
3. Edit and Format – Use a function node to format the AI’s response
4. Send Email Node – Automatically send the reply back to your user

You can test each step live and tweak things as you go. And once you’re happy, just hit “Activate.” Your AI workflow now runs 24/7 in the background.

Need help? You can also browse pre-built templates in the n8n library and customize them for your use case.

 

Step 4: Schedule or Trigger Workflows Automatically

n8n lets you run workflows in two ways:

• Scheduled – Run automations daily, weekly, or every few minutes
• Triggered – Start automations when something specific happens (like someone fills out a form, buys a product, or sends a message)

You can even connect n8n to webhooks, which means it can react instantly to events from apps like Stripe, Calendly, or Typeform.

 

Step 5: Add More Tools to Your Workflow

One of the best parts about n8n is how easily you can stack tools together.

Here are a few real AI automation ideas:

• Auto-write blog outlines using OpenAI + Google Docs
• Generate personalized cold emails from a spreadsheet
• Respond to Instagram DMs using ChatGPT and a webhook
• Summarize long emails and forward key points to Slack

You can mix and match tools based on what your business needs, and because it’s open source, the limits are up to you.

 

Final Thoughts

Setting up n8n might sound technical at first, but it’s one of the most powerful ways to automate your business using AI, without paying monthly fees or being stuck with rigid platforms.

Once it’s live, you can build workflows that run on autopilot, save hours every week, and help you scale smarter. And with tools like Hostinger offering pre-installed templates, getting started is easier than ever.

If you’re serious about using AI to automate your business, don’t sleep on n8n. It’s free, flexible, and insanely powerful once you learn how to use it.
