How to Build a Cheap Home Server to Save Money on Subscriptions

Building your own home server in 2026 is more of an investment than anything else. The upfront costs will be offset by the lack of need to subscribe to streamers for movies, TV and music. Self-hosting can also scale to your needs, so you don’t need to hunt for an old desktop machine, but you can opt for something as small as a Raspberry Pi, or one of the more powerful alternatives. In fact, if you’re just starting out, it might be worth pulling out an old Mac Mini or PC and using it as the basis for your cheap server.

Of course, this wouldn’t be a tech article in 2026 without mentioning that prices are sky-high right now. AI data centers and other global events have impacted the prices of almost anything you would want to purchase for this type of project. Even the humble Raspberry Pi now costs hundreds of dollars, all because RAM is very hard to get these days. If you have an old PC lying around or you’ve found a good deal and want to get started, you have a few options, but your best bet is to run a Linux distro for maximum compatibility and flexibility, and it’s free.

We’ll also talk about Docker, which is software that hosts other software (images) in “containers”, keeping them separate from the main PC. If they crash or have a problem, it will only impact the container and other connected containers.

Setting up your server for the first time is simple, just like installing a regular operating system. We use Ubuntu Server, but you can opt for Debian – or Pi OS Lite for Raspberry Pi – for a minimal operating system footprint. Server operating systems tend not to have a graphical user interface (GUI). Technically you can embed this, but the majority of what you’ll do will be in file explorer applications on another PC or in the web browser for Docker applications. When you boot after the first installation, you will encounter a black terminal interface. Ignore all of this unless you are always setting up different users.

On another PC, you can connect via Secure Shell (SSH) in your favorite terminal on Linux and macOS or via Command Prompt, Windows Terminal, or PowerShell on Windows. To do this, open the terminal and type “shh @.“If you share a username with the device, you don’t need to add the username at the beginning. It will ask you for the password and you can log in. Before continuing, it’s best to update the entire server. Each distribution uses a different package manager, so you’ll need to find it first.

Typically on Ubuntu and Debian, it’s “sudo apt update” to fetch new packages, and “sudo apt upgrade” to completely upgrade everything. You’ll use a bit of ‘sudo’ here. That means ‘superuser do’. From there, the sky’s the limit. Some recommendations to look into are the free media streamer Jellyfin, the Komga comic book reader and host, or even setting up a WireGuard VPN for remote access to your home network. Some of these will run on ‘bare metal’, directly on the PC, while others will leverage Docker.

You’ll need to install Docker first, and it’s best to familiarize yourself with the documentation now. On Debian or Ubuntu, you’ll first need to update the package list to acquire Docker, but once that’s done, it’s quick to launch some of these applications. One item you will encounter when installing Docker applications is the “Docker Compose” file. Not all applications need this, but if you want more manual control over your data in a clear way, be sure to set up a folder on the server to store it.

These Compose files can be activated by navigating to the directory they are stored in (using CD ) and using “sudo docker-compose up -d” to activate the installation. Compose files are YAML files, so they will need to be saved in .yml format. On Windows, in Notepad, when saving, you will need to use the drop-down menu in the Save menu to choose “All Files”, then name it “docker-compose.yml”. Docker does not use the standard directories, but has its own separate space that reflects the storage you have pointed it to. In Compose files, this will often look like:

volumes:
    - type: bind
    source: /path/to/your/directory
    target: /a/folder/in/Docker

This may trip up some people, but essentially you will grab the directory you want the Docker application to use and then it will convert it to a particular folder. Some Docker programs will provide a basic Compose file that you can use and configure to match your system. Otherwise, you may find that the program takes over and creates for you an entire directory of folders called “/path/to/your/directory.“From there, you just need to fill up the storage you have connected to your cheap server.
