Guides to running a server on your Mac
Practical guides to using an Apple silicon Mac as a real server: running Linux on it, serving a site from home, keeping it awake, and whether it beats a VPS.
A Mac that sits idle most of the day is a server you have already paid for. An M-series machine draws a few watts doing nothing, has fast storage, and has enough memory to run several services at once. It is quiet enough to leave on a shelf and forget about.
The obstacles are not the hardware. They are that macOS is not the operating system your software expects, that home internet connections are built for downloading rather than serving, and that a laptop's first instinct is to go to sleep. These guides cover each one, including the cases where the answer is that you should rent a server instead.
