Open-Source Redmine Alternatives (2026)

Redmine is itself open source, released under the GNU General Public License v2, so this page is for teams that want a different feel rather than a different licence. Common reasons: a more modern interface, built-in boards and roadmaps, or a hosted option from the same vendor.

Every tool below is under an OSI-approved licence (GPL-3.0, AGPL-3.0 or MIT), checked against its repository. Planka, a popular Kanban tool, uses a fair-code licence and is listed separately at the end.

Licences checked against each repository on November 7, 2026.

What you're replacing

Often called open source, but aren't

Public source code, but under licences the Open Source Initiative doesn't approve. Fine to use; read the terms first.

  • Planka (Fair Use License / PLANKA Pro and Enterprise License)

    Source is public and a free Community edition is self-hostable, but the repository describes it as fair-code rather than open source. A paid Pro tier exists.

Open-source Redmine alternatives: FAQ

Quick answers to common questions

Is Redmine open source?

Yes. The Redmine site states it is released under the terms of the GNU General Public License v2.

What is the best open-source Redmine alternative?

OpenProject has the closest scope, with work packages, Gantt charts and role-based access. Plane is the more modern option for sprint-based teams.

Can I migrate Redmine issues?

Some tools offer importers, but custom fields and workflows rarely transfer cleanly. Test with a copy of one project and check each tool's docs for import support.

Is Planka open source?

Its repository describes it as fair-code distributed under a Fair Use License with a separate Pro/Enterprise licence, so it is not listed as OSI open source here.

Which of these is easiest to self-host?

Kanboard is the lightest to run. OpenProject, Plane, Leantime and Vikunja are commonly deployed with Docker.
