Docmost
Depends
Confidence: Medium
Buy if you want a cheap, self-hosted Confluence/Notion replacement and have someone who can run a server.
| Compare | MediaWiki | Docmost |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Large public knowledge bases | Regulated teams requiring self-hosting |
| Who it's not for | Small teams wanting a quick internal wiki | Non-technical teams with nobody to run a server |
| Privacy | Actively maintained with a dedicated security team, but a steady stream of CVEs means prompt patching is mandatory.⁹ | No known public vulnerabilities found in the sources reviewed. |
| Support quality | Guess: community forums only; no vendor SLA. | No support evidence in sources reviewed |
| Public sentiment | Reddit users find MediaWiki powerful but repeatedly call it too complicated and maintenance-heavy for casual users and small teams.¹ | Self-hosters on Reddit and forums pitch it as a lighter, cheaper Confluence/Notion alternative, but in-depth user reviews are still scarce. |
| Biggest gotcha | Multiple 2026 CVEs including auth bypass and stored XSS; patch fast.⁹ | Community Edition has no SSO . a hard blocker for many companies; Enterprise pricing isn't public. |
