Wiki.js
Open-source self-hosted wiki on Node.js and PostgreSQL; 3.x (stable since Nov 2026) is the current major version
Our verdict
#3 of 7 in Self-hosted team wikis · Git sync and sign-in depth, in a brand-new version
Pros
- Two-way Git sync and automatic backup to S3, Azure, Google Cloud or SFTP
- OIDC, LDAP and SAML with group mapping, SCIM, page rules and an audit log
- Markdown, visual and AsciiDoc editors; Live Notes for co-editing
- AGPL, described as free forever with no paid edition
Cons
- Version 3 is a ground-up rewrite with a short track record
- Moving from version 2 means export and re-import, and some settings are redone by hand
- Version 3 needs PostgreSQL 17 or 18
Choose if: You want pages mirrored to a Git repository and can wait for version 3 to settle, or can run the long-standing version 2.
Skip if: Teams that want software with years of proven version 3 releases behind it.

“My honest take: try it now, and move production when you've tested your own content. Wiki.js 3 is days old.”

“The first stable 3.0 release landed on November 1, 2026, and the project calls it "a complete rewrite of both the backend and frontend." The upgrade guide is blunt: "an in-place upgrade is not possible."”

“That's a good sign for how the project handles reports, but it also means you should start on 3.1.0 or newer, not 3.0.x.”
