Some people (including myself) might not want emoji rendering, though.

It's extremely simple and straightforward for networking devices. Setting up an OpenBSD router or gateway is such a pleasant process.

The documentation in all aspects is superb, and you can run all sorts of servers just fine (ports is full of common software). You can technically use it as a desktop workstation too, but I can't point to anything that really stands out in this aspect — except perhaps the strong focus on security.

I think where obsd really shines is in the small infrastructure department, name servers, routers, time servers, web servers, mail servers. Obsd boxes tend to be easy to administrate, predicable and most importantly boring. It is a great system to build the back end of your small business or home network.

Personally I think it also makes for a very nice desktop system. But I like my desktops thin, a tiling window manager and lots of terminals. If you enjoy fat desktops, there may be a bit more friction. One reason I like it for desktop use more than other systems is that the software packaging feel higher quality. It is not a huge difference. mainly I have found obsd packages to more reliably work when installed. and those heroic obsd package maintainers tend to put a note in /usr/local/share/doc/pkg-readmes/ that will get you started.

It’s my daily driver. Simple and it works.

So many use cases. It serves as my mail server because it is secure and simple. It serves as my gateway via wireguard to my homelab. It serves as a daily driver on my x220. It is a simple and straightforward operating system. It can 100% serve you as a daily driver even on desktop (excluding maybe running Steam).

But the simplicity also yields stability. Upgrading Arch for example can sometimes backfire. Upgrading OpenBSD? Almost blindly. It just works (tm).
