How to Self-Host Coolify for €3.79/Month (Full Setup Guide)

Most developers I know are paying $50+ per month for managed hosting when they could be running the same stack for under $5.

I just released a complete tutorial on self-hosting Coolify on Hetzner. This covers everything you need to go from zero to a working deployment platform with HTTPS.

What you'll learn:

• SSH security setup - Moving from password authentication to SSH key pairs (and why this matters)

• Firewall configuration - Blocking unnecessary ports and restricting access to only what you need

• Domain configuration - Setting up wildcard domains so you can host multiple apps under clean subdomains

• SSL automation - Getting Let's Encrypt certificates working automatically

• Practical deployment - Installing ActivePieces as a real example (applies to n8n, databases, and other tools)

Technical decisions covered:

The video walks through choosing between shared vs dedicated CPUs, x86 vs ARM64 architecture, and explains the tradeoffs. I also cover DNS A-record setup, SSH daemon configuration, and how Coolify's proxy system works.

Who this is for:

If you're running automation tools (n8n, ActivePieces, etc.) or want to host your own databases and services, this gives you full control over your infrastructure at a fraction of typical cloud costs.

Fair warning: You're responsible for maintenance and keeping things running. This isn't a "set it and forget it" managed solution, but you get complete control and significant cost savings.

The setup:

At €3.79/month, the server I use in the tutorial has 2GB RAM and 40GB storage—enough to run multiple automation workflows and apps. The video is 23 minutes and includes all terminal commands.

P.S. - If you're interested in more advanced setups (like running Coolify on one server while deploying apps to separate servers), let me know. I'm planning a follow-up on multi-server architectures.

Best,
