MediaWiki
Depends
Confidence: Medium

Comparison
MediaWiki vs XWiki
MediaWiki and XWiki both land on Depends.
XWiki
Depends
Confidence: Medium
Buy if you're a mid-size or larger org with IT staff who want an open-source Confluence alternative.
| Compare | MediaWiki | XWiki |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Large public knowledge bases | Docs-heavy enterprises |
| Who it's not for | Small teams wanting a quick internal wiki | Small teams wanting a simple shared wiki |
| Privacy | Actively maintained with a dedicated security team, but a steady stream of CVEs means prompt patching is mandatory.⁹ | Active exploitation of an unauthenticated RCE in 2025 plus further CVEs into 2026 . patch fast or use managed hosting. |
| Support quality | Guess: community forums only; no vendor SLA. | Active forums; vendor support requires paid contract |
| Public sentiment | Reddit users find MediaWiki powerful but repeatedly call it too complicated and maintenance-heavy for casual users and small teams.¹ | Power and value win fans, but recurring complaints call it too complex for simple needs and question its Confluence-parity.15 |
| Biggest gotcha | Multiple 2026 CVEs including auth bypass and stored XSS; patch fast.⁹ | Unauthenticated RCE (CVE-2025-24893) exploited in the wild; botnet hit 3,400+ instances. Patch immediately. |
