Mediawiki has worked well. I’d be curious to hear others experiences with it. VisualEditor is an extremely good WYSIWYG interface. The wiki is able to scale well (project sites are unlikely to approach Wikipedia scale). The API is useful. Wikitext editing gives power users a lot of flexibility, though it’s not as popular as Markdown. Access control & edit-publish workflow options may be too limited for the desires of some project teams.
