Why Run n8n on a Raspberry Pi 5

Low Power, High Performance

The Raspberry Pi 5 is significantly faster than its predecessors, with better I/O capabilities, a quad-core CPU, and support for faster storage. This makes it ideal for running self-hosted tools like n8n.

Cost-Effective Automation Platform

Compared to cloud servers, a Raspberry Pi offers a one-time investment. You avoid monthly fees while maintaining control over your data and uptime.

Ideal for Learning and Prototyping

Running n8n on a Raspberry Pi 5 is also perfect for developers, students, and tinkerers who want to explore workflow automation in a hands-on environment.

Requirements and Preparations

Hardware Requirements

  • Raspberry Pi 5 (4GB or 8GB RAM)

  • microSD card (32GB or more)

  • Power supply for Raspberry Pi 5

  • Active internet connection

Software Requirements

  • Raspberry Pi OS (64-bit recommended)

  • Docker & Docker Compose installed

  • Terminal access (SSH or direct)

Step-by-Step Guide to Run n8n on a Raspberry Pi 5

Step 1: Update Your System

Open the terminal and run:

sudo apt update && sudo apt upgrade -y

This ensures your Pi is running the latest packages for optimal performance.

Step 2: Install Docker and Docker Compose

Install Docker:

curl -sSL https://get.docker.com | sh

Add your user to the Docker group:

sudo usermod -aG docker $USER

Install Docker Compose:

sudo apt install docker-compose -y

Reboot to apply changes:

sudo reboot

Step 3: Set Up n8n Directory

Create a working directory:

mkdir ~/n8n && cd ~/n8n

Step 4: Create Docker Compose File

Use your text editor to create the file:

nano docker-compose.yml

Paste the following content:

version: '3'
services:
  n8n:
    image: n8nio/n8n
    restart: always
    ports:
      - "5678:5678"
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=admin
      - N8N_BASIC_AUTH_PASSWORD=securepassword
      - N8N_HOST=localhost
      - N8N_PORT=5678
      - TZ=UTC
    volumes:
      - ./n8n:/home/node/.n8n

Step 5: Start the n8n Service

Launch n8n:

docker-compose up -d

Access your instance by visiting:

http://<raspberry_pi_ip>:5678

Use the username and password you defined earlier.

Optimizing n8n on Raspberry Pi 5

Enable Persistent Data Storage

Ensure your workflows are saved even after reboots by using persistent volumes, as shown in the Docker Compose file.

Use External Database (Optional)

For advanced use cases, consider configuring PostgreSQL instead of SQLite to handle larger workflows more reliably.

Set Up a Reverse Proxy

Use Nginx or Caddy for HTTPS and domain-based access, which improves security and convenience.

Pros and Cons of Running n8n on Raspberry Pi 5

Pros

  • Low-cost and energy efficient

  • Full control over automation workflows

  • Great for testing and learning

  • Works well for light to medium workloads

Cons

  • Limited for heavy enterprise-scale workflows

  • Requires basic Linux and Docker knowledge

  • Less performant than cloud VMs for high concurrency

Comparison: Raspberry Pi 4 vs Raspberry Pi 5 for n8n

The Raspberry Pi 5 offers up to 2x performance boost over the Pi 4, especially in disk I/O and networking. For running n8n on a Raspberry Pi 5, this means faster deployment, better stability under load, and smoother user experience.

If you’re using heavier nodes or integrations (e.g., with databases or external APIs), the Pi 5 handles them much more efficiently.

FAQs

What is n8n and why should I self-host it?

n8n is an open-source workflow automation tool that lets you connect apps and automate tasks. Self-hosting it on a Raspberry Pi 5 gives you data privacy and full control.

Can I run n8n without Docker on Raspberry Pi 5?

Yes, you can install n8n globally using Node.js, but using Docker is simpler, more portable, and better for long-term maintenance.

Is the Raspberry Pi 5 powerful enough for production?

For small to medium workflows, absolutely. If you scale to hundreds of daily jobs or use large integrations, you may eventually want to upgrade to a dedicated server.

How do I secure my n8n instance?

Use basic authentication, HTTPS via Nginx/Caddy, firewall rules, and avoid exposing ports publicly unless necessary. Always keep your system updated.

What are the best use cases for n8n on Raspberry Pi?

  • Home automation

  • Social media scheduling

  • API data syncing

  • Email automation

  • Local backups and notifications

Final Thought

If you're looking for a private, cost-effective way to automate tasks, running n8n on a Raspberry Pi 5 is one of the best solutions available. The Pi 5 delivers strong performance, low energy usage, and a robust ecosystem.

With just a few terminal commands and Docker, you’ll have your own automation server running in no time. Start small, and you’ll be surprised how powerful your Raspberry Pi can be.
