What the free edition leaves out
The free edition is genuinely usable, but some team or enterprise features need a paid plan. “Not confirmed” means the official pages we read did not say, so we do not guess.
| Feature | Free edition | Details | Source |
|---|---|---|---|
| SSO / SAML | Paid | The pricing page lists single sign-on (CAS, SAML, OpenID Connect, Kerberos, Okta) as an Enterprise add-on, and the OpenID providers docs say OpenID Connect providers is an Enterprise add-on. LDAP authentication is listed as Community. Exact tier for SAML was not stated. | Source ↗ |
| Role-based access control | Free | Group management and detailed permissions are listed under Community features. | Source ↗ |
| Audit logs | Not confirmed | Not mentioned on the pricing page. | Source ↗ |
| Multi-user / teams | Free | Community edition is free with no minimum users listed; paid plans have minimum user counts (25 for Basic and Professional). | Source ↗ |
| Backups and restore | Free | DEB/RPM packages include a backup tool ('openproject run backup'). Docker installs use pg_dump and volume backups. | Source ↗ |
| API access | Free | REST API is listed as a Community feature. | Source ↗ |
| Support SLA | Paid | Community support is forum and tickets, best effort, no SLA. Paid plans list response times for critical issues (Basic 8h, Professional 6h, Premium 2h). | Source ↗ |
Best for
Teams that need Gantt-based planning, work packages and agile boards in one self-hostable tool.
Why choose it over Jira
The Community edition is free and can be run on your own server. Per the pricing page it includes Gantt charts, Scrum and Kanban boards, time tracking and costs, group management with permissions, LDAP authentication and a REST API.
Where it falls short
Single sign-on (including OpenID Connect and SAML) is an Enterprise add-on, as are LDAP user and group sync, some Gantt and custom field features, and multiple active sprints. Paid plans have minimum user counts. Audit logs were not found on the pages read. Full backup tooling exists only for DEB/RPM installs; Docker installs rely on manual dumps. Running it needs a server with a PostgreSQL database and is heavier than a simple task tool. A feature comparison with Jira was not done.
