Docmost vs Alternatives

FAQ

Q: What team sizes is Docmost suitable for? A: From small teams to organizations with hundreds of people. The PostgreSQL backend ensures good scalability. If you have 100+ concurrent editors, consider increasing Redis and application-tier resources.

Q: Can I migrate from Confluence? A: Yes. Docmost supports importing XML files exported from Confluence, including page hierarchy, attachments, and basic formatting. Complex Confluence macros may require manual adjustment.

Q: SSO/LDAP support? A: Supports SAML SSO and Google OAuth login. LDAP support is on the roadmap.
