What is your favourite selfhosted wiki software and why?
There are a ton of options listed on the Awesome Selfhosted list. I'm on the search for a FOSS option that I can use to document my homelab and personal tech projects.
I've been using Wiki.js since I asked this question a few months ago. I've been pretty happy with it. Stores data in text files using markdown and can synchronize a number of backends. I've got mine syncing to a private github repo.
