How to Host n8n with Coolify on Google Cloud for Free in 2026: The Complete Step-by-Step Guide

If you’re looking for the best way to host n8n for free, you’ve probably come across dozens of tutorials that leave out important details.

Many guides tell you to deploy n8n on Google Cloud, install Coolify, connect a domain, and you’re done.

The problem is that most tutorials ignore Google’s free tier limitations and Coolify’s hardware requirements. As a result, many users end up with unexpected bills, server crashes, or painfully slow automation workflows.

• Production-ready webhooks

• A setup that can scale as your automations grow

What Is n8n?

n8n is an open-source workflow automation platform that allows you to connect apps, APIs, databases, AI models, CRMs, spreadsheets, and business systems without writing extensive code.

Popular use cases include:

• AI agents

• WhatsApp automation

• Telegram bots

• Lead generation

• CRM workflows

• Google Sheets automation

• Email automation

• Social media automation

• Data synchronization

Unlike Zapier or Make, n8n gives you full control when self-hosted.

What Is Coolify?

Coolify is an open-source alternative to Heroku, Railway, and Render.

It allows you to deploy applications using Docker without manually configuring complex infrastructure.

Coolify supports:

• Docker containers

• Docker Compose

• PostgreSQL

• Redis

• Static websites

• Node.js applications

• Python applications

• n8n deployments

According to Coolify’s official documentation, self-hosting is free apart from your server costs.

Can You Host n8n on Google Cloud for Free?

Yes, but there is an important distinction.

Google Cloud offers:

Option 1: Always Free Tier

Google’s Always Free tier includes:

• One e2-micro VM

• Up to 30 GB standard persistent storage

• Up to 1 GB outbound transfer monthly

These resources are available to eligible customers without expiration.

Option 2: $300 Free Trial Credits

New Google Cloud users receive $300 in trial credits valid for 90 days.

This allows you to run larger virtual machines suitable for production workloads.

The Biggest Mistake Most Tutorials Make

Most tutorials recommend:

“Create an e2-micro VM and install Coolify.”

The issue is that Coolify officially recommends:

• 2 CPU cores

• 2 GB RAM

• 30 GB storage minimum

for reliable operation.

Meanwhile, Google’s free e2-micro instance only includes:

• 2 vCPUs

• 1 GB RAM

• 30 GB storage allowance

within the free tier.

Can it work?

Yes.

Should you run production automation workloads on it?

Probably not.

Recommended Architecture

Your final infrastructure should look like this:

User

↓

Cloudflare

↓

n8n.yourdomain.com

↓

Google Cloud VM

↓

Coolify

↓

Docker

↓

n8n

↓

Persistent Storage

This architecture provides:

• SSL security

• Easier DNS management

• Better performance

• Protection against direct server exposure

Step 1: Create a Google Cloud Account

Visit:

Google Cloud Platform

Create a new project.

Enable billing.

If you’re a new user, your account should qualify for the $300 free trial credits.

Step 2: Enable Compute Engine

Inside Google Cloud:

Compute Engine → VM Instances

Enable the Compute Engine API if prompted.

Step 3: Create Your Virtual Machine

Recommended settings:

Machine Name:

n8n-coolify

Operating System:

Ubuntu 24.04 LTS

Region:

us-central1

Machine Type:

e2-medium

Storage:

30 GB

Enable:

• HTTP traffic

• HTTPS traffic

If your goal is true zero-cost hosting, choose e2-micro.

If your goal is stability, choose e2-medium and use trial credits.

Step 4: Connect to Your Server

Open Compute Engine.

Click SSH beside your VM.

Update Ubuntu:

sudo apt update && sudo apt upgrade -y
sudo reboot

Reconnect after reboot.

Step 5: Install Coolify

Run:

curl -fsSL https://cdn.coollabs.io/coolify/install.sh | sudo bash

This is Coolify’s official installation method.

The installer automatically:

• Installs Docker

• Configures Coolify

• Creates required directories

• Starts services

Step 6: Access Coolify

Open:

http://YOUR_SERVER_IP:8000

Create your administrator account.

Complete the onboarding process.

Step 7: Create an n8n Project

Inside Coolify:

Projects

↓

Create New Project

↓

Name:

n8n

Step 8: Deploy n8n with Docker Compose

Create a new Docker Compose resource.

Paste:

services:
  n8n:
    image: docker.n8n.io/n8nio/n8n:latest
    restart: unless-stopped

    environment:
      - N8N_HOST=${N8N_HOST}
      - N8N_PROTOCOL=https
      - WEBHOOK_URL=https://${N8N_HOST}/
      - N8N_EDITOR_BASE_URL=https://${N8N_HOST}/
      - TZ=Africa/Lagos
      - GENERIC_TIMEZONE=Africa/Lagos

    volumes:
      - n8n_data:/home/node/.n8n

volumes:
  n8n_data:

Step 9: Connect Your Domain

Purchase a domain or use an existing one.

Create:

Type: A
Host: n8n
Value: YOUR_SERVER_IP

Example:

n8n.yourdomain.com

Step 10: Configure Environment Variables

Inside Coolify:

Environment Variables

Add:

N8N_HOST=n8n.yourdomain.com

Step 11: Deploy n8n

Click Deploy.

Coolify will:

• Pull the Docker image

• Create containers

• Configure networking

• Start n8n

Deployment usually takes a few minutes.

Step 12: Secure with HTTPS

Add your domain in Coolify.

Coolify automatically manages SSL certificates through its reverse proxy infrastructure.

You should now be able to access:

https://n8n.yourdomain.com

Step 13: Create Your n8n Account

Open your n8n URL.

Create:

• Owner account

• Username

• Password

• Workspace settings

You now have a working n8n installation.

https://n8n.yourdomain.com/webhook/abc123

If the webhook receives requests successfully, your production environment is ready.

How to Avoid Unexpected Google Cloud Charges

Most accidental charges come from:

• Snapshots

• Extra storage

• Static IP misuse

• Bandwidth overages

• Additional VM instances

Many users discover that the VM itself is not the problem. Storage and snapshots often generate the unexpected charges.

Create billing alerts:

Should You Use PostgreSQL Instead of SQLite?

For learning purposes:

SQLite is fine.

For client projects and production workloads:

Use PostgreSQL.

Benefits:

• Better reliability

• Improved performance

• Easier backups

• Better scalability

Coolify supports PostgreSQL deployment directly.

Final Thoughts

If your goal is to learn automation, build AI agents, automate business processes, or deploy client workflows, hosting n8n with Coolify on Google Cloud is one of the most flexible setups available.

The key takeaway is simple:

Google Cloud’s Always Free tier can work for experimentation.

Google Cloud trial credits are better for serious deployments.

Start small, monitor billing carefully, connect a custom domain, and upgrade your infrastructure only when your automation workload demands it.

That approach gives you a reliable, scalable, and low-cost n8n hosting environment that you fully control.
