Just curious: any features (from your point of view obviously) making it a better choice compared to i.e free version of GitLab?
I've never used gitlab so I can't say. We use gitea. I thought gitlab was some kind of github alternative, like gitea. It's a wiki too now?
Well, both GitHub and the GitLab have wiki functionality.
Not on par afaik with more familiar MediaWiki but nevertheless good enough for not just software project documentation.
No experience with transforming these wikis into stand alone web sites with different styles etc.
