For a very special type of server hardware, the Raspberry Pi micro-computers (the version 3), the MAZI project produced in 2018 a pre-installed "image" that transforms with minimal effort a Raspberry Pi to a web server allowing its administrator to choose from a wide variety of services.
Unfortunately, the software was not maintained for Raspberry Pi 4, and being designed with priority for offline use, it is now susceptible to the lack of support for https.
Still if you have a Raspberry PI 3, you can use it!
