The Narrow Road to Self-Hosting

Self-hosting with VPS, Docker, and Coolify

Self-hosting means running applications and services on your own server.
Instead of relying on managed platforms like Heroku or Vercel, you own the infrastructure and decide flexibility, cost, and how data is handled.

This guide keeps things simple and focuses on:

• A modern, common stack (VPS, Docker, PaaS-style management tools)
• Secure operations basics (SSL, backups, updates)
• Building your own apps and deploying them to production

It is for beginners to server operations and for engineers who want hands-on control of infrastructure.

VPS (Virtual Private Server)

A VPS is a virtual server you rent in the cloud.
It is cheaper than a dedicated server and lets you install the software you need.

This guide assumes a VPS for these reasons:

• Fixed monthly cost, often from a few dollars to a few tens of dollars
• Root access so you control the server layout
• No limits on installing standard self-hosting tools such as Docker and Coolify

Docker

In modern server operations, apps, middleware, and databases usually run in Docker containers.
A Docker container isolates an app in a lightweight environment.

Docker helps you:

• Reduce “works on my machine” gaps between local and production
• Keep dependencies separate per app
• Improve reproducibility for migration and backups

The PaaS-style tools in this guide also manage apps on top of Docker.

Coolify (self-hosted PaaS)

PaaS (Platform as a Service) normally means a hosted platform that runs your apps—Heroku and Render are typical examples.

Coolify, by contrast, is a self-hosted management tool that brings a PaaS-like experience to your own VPS.
You can deploy apps and configure domains from a browser, and manage Docker container lifecycles through a GUI.

Main benefits of Coolify:

• Multiple domains and applications
• Automatic SSL/TLS certificates via Let’s Encrypt
• Deployments linked to Git

Coolify is our recommended standard setup.
This guide walks through real operations centered on Coolify.
