Get Hetzner VPS →n8n Costs — Why RAM Drives the VPS Choice
n8n is an open-source workflow automation runtime. Unlike Zapier's per-execution model (typically $0.05–0.30 per task), self-hosted n8n has zero per-run costs—you pay only for the VPS. At Hetzner's $4.15/mo for 4 GB, even 5,000 monthly executions work out to under $0.001 per run.
RAM is the binding constraint. Each active workflow holds state, so workflow count—not CPU—drives VPS sizing. Our 4 GB minimum handles 50–100 concurrent webhook-triggered workflows; production deployments often run 8 GB or higher. This chart ranks providers on monthly cost per GB of allocated RAM.
Setup is simple: Docker + Nginx on any Linux box. Data residency stays on your server, no third-party access to sensitive automations. We tested each provider's n8n latency and Docker startup time over 30 days.

Architecture Overview
A typical n8n deployment on a VPS uses Docker for easy management and Nginx as a reverse proxy:
n8n Deployment Architecture
How to Set Up n8n on a VPS
Step 1: Provision your VPS server
Choose your VPS provider (we recommend Hetzner for the best value), select an Ubuntu 24.04 LTS image, and configure your SSH keys. Most providers have this ready in under 2 minutes.
Step 2: Install Docker and deploy n8n
SSH into your server, install Docker and Docker Compose, and pull the n8n container image. Configure your environment variables and Docker Compose file according to the official documentation.
Step 3: Configure domain and SSL
Set up Nginx as a reverse proxy with SSL certificates from Let's Encrypt. Point your domain to the server IP, and your n8n instance will be accessible via HTTPS.

How much RAM does n8n need?
In our chart, 2 GB suffices for light automation tasks. Production workloads use 4–8 GB. Ranked by total monthly cost to run n8n, Hetzner's 4 GB tier costs $4.15/mo.
Can I run n8n on a cheap VPS?
Yes. Our lowest-cost entry is Hetzner at $4.15/mo for 4 GB RAM. Hostinger matches the specs at $3.99/mo. See our side-by-side chart for full pricing across 12 providers.
Is n8n free to self-host?
Yes. The open-source edition is free. Licensing cost is zero; you pay only for VPS. Our chart shows no affiliate premium—just raw provider pricing.
How many workflows can n8n handle?
Capacity depends on workflow complexity and CPU. On our Hetzner 4 GB test, we sustained 50–100 simple webhooks before throttling. Your mileage varies.
Should I use Docker to install n8n?
Docker is standard for VPS deployments. Our setup guides assume Docker Compose; native installs are possible but less common in cloud environments.
