Docmost vs Wiki.js: which one to choose in 2026?

Both are open source alternatives to Confluence. We compare license, tech stack and features to help you decide which fits your team best.

Quick answer: Wiki.js and Docmost are both AGPL-3.0, but technically different: Wiki.js only needs PostgreSQL and offers Git-style change history with multiple auth providers; Docmost adds Redis and focuses on real-time collaborative editing in a Notion-like style.
