My own, PhpWiki, heavily customized and integrated with a search engine.

Confluence or SharePoint are horrible, MediaWiki is lame. DokuWiki is nice. But most important is the content, not the platform.

Yeah we thought about confluence but we also use notion and a bunch of other tools that makes it hard to integrate stuff. That was our dealbreaker (we're not married to jira yet(:_ What don't you like about Confluence?

I like DokuWiki. I use it for personal projects but I couldn't picture it being used as an enterprise tool.
