When embarking on a self-hosting adventure, one crucial decision awaits: selecting the underlying operating system for applications like Jellyfin, Immich and Home Assistant.
When it comes to self-hosting applications, the choice between Windows and Linux isn't about personal preference, but rather about finding a solution that meets specific needs. Efficiency, reliability, and flexibility are key considerations. Linux consistently emerges as the top contender.

›Less demanding on system resources.
When designing a server, it's essential to consider resource consumption to avoid unnecessary strain on the system. A lightweight variant of Ubuntu or Debian can function efficiently with minimal RAM requirements, approximately 200-300 megabytes. In contrast, Windows typically utilizes several gigabytes of memory even when idle, which may restrict hardware choices for servers. This can be a concern for users who require robust server capabilities.
When repurposing older devices like laptops or desktops, it's crucial not to sacrifice performance, which often hinges on having sufficient RAM capacity available.

Debian and Ubuntu Server variants in headless mode typically consume between 200-400 megabytes of Random Access Memory (RAM). Meanwhile, Windows systems require significantly more RAM, often several gigabytes, before launching initial applications.
The available system resources dictate what hardware is feasible for use. Repurposing an old laptop or a $150 mini PC, such as a Raspberry Pi, makes Linux the most practical operating system choice. Losing significant percentages of total resources isn't economically justifiable. Server management typically occurs through SSH, which conserves system resources compared to running a full desktop environment that's only necessary 99% of the time.
System resource utilization is not just about RAM capacity. The issue of control also plays a significant role, particularly for systems that require constant accessibility. Windows Update's propensity for updating at unpredictable times can be a recurring challenge for 24/7 operations. In contrast, Linux offers flexible patch management and reboot control, while systemd ensures seamless service recovery in the background.
My Linux servers can operate for extended periods without manual intervention, typically lasting months between restarts triggered by power outages. Conversely, my Windows PC experiences frequent involuntary shutdowns, occurring multiple times per month. This unpredictability can be frustrating when hosting critical services like game servers or streaming platforms that require consistent availability.
11Linux dominates the self-hosting landscape fundamentally.
›Windows support is a secondary priority.
Most online resources about self-hosting focus primarily on Linux, with a vast majority of guides, scripts, and forums catering specifically to this operating system. Consequently, first-party documentation for self-hosted projects also tends to favor Linux, leaving Windows users with limited support options available.
Despite their user-friendly interfaces, Proxmox, TrueNAS, and others rely on Linux beneath the surface. Self-hosting on Windows means devoting considerable time to adapting found solutions to accommodate its unique requirements before they're usable.
›Docker performance on Windows is comparable.
Proponents of using Windows for self-hosting often cite Docker's ability to run on their platform as a key advantage. Yet this claim crumbles when one digs deeper into the underlying mechanics of how Docker operates on Windows systems.
Docker Desktop on Windows operates by running each Linux container within a WSL2 virtual environment, effectively allowing Windows to serve as a platform for a Linux-based system. This setup enables Linux to act as the app host.
Introducing an intermediary in this approach comes at a cost: resource utilization increases significantly. As a result, VM memory is allocated upfront, leading to slower I/O operations and additional debugging complexities when issues arise inevitably.
Running containers directly on a Linux environment can be a straightforward approach.

›Investing in Linux initially yields long-term benefits for self-hosted applications.
Self-hosted applications thrive with Linux as the foundation due to its widespread adoption in the self-hosting community. Containers on Windows operate within a Linux virtual machine environment, leveraging Linux's inherent advantages. By opting for Linux, users can enjoy reduced idle resource demands and access an extensive library of documentation without unexpected system restarts.
With minimal effort, anyone can transform an outdated PC or laptop into a Proxmox setup within an hour to two hours, even for complete beginners. Subsequently, creating a virtual machine with customizable system specifications and installing Docker Engine and Compose via the official script requires only an additional 20 minutes of time.
Early effort pays off, as upfront time spent on mastering Linux leads to significant reductions in later troubleshooting sessions.
