Ethan Sholly, the driving force behind selfh.st, one of the most recognized communities uniting self-hosting enthusiasts, has published the latest results of his annual survey on the community’s preferences, collecting 4,081 responses from self-hosting practitioners worldwide.
No surprise there: Linux is overwhelmingly dominant, chosen by more than four out of five self-hosters (81%). In other words, for self-hosters operating at bare-metal, virtualised, or container-based infrastructure, Linux remains the backbone.
In fact, this result aligns closely with broader trends: according to Wikipedia, Linux holds a 63% share of global server infrastructure. Aside from the hobby aspect, most respondents said privacy was their main reason for self-hosting, which, as you know, remains one of Linux’s strongest selling points. Now, back to the numbers.
in addition to what others have said, i’d say a lot of civil infrastructure—hospitals, clinics, government facilities, etc—are locked in either because of bad politics or weird vendor lock in. my dad ran his own dental clinic, and he had to run a Windows server because it was required by his software vendor that did everything from appointment reminders, to the web portal, to billing, to showing which of your teeth were missing, to integrating with scanners or other equipment. it was shit software that looked like Windows 3.1 well into the 2020s, but it did the job and 24hr support was reliable. just an anecdote, but as a software engineer i was fascinated by it.
