Open Source Alternatives to Trello
Transparent & Community-Driven

Replace Trello with open-source software you can inspect, modify, and self-host. No vendor lock-in, no hidden costs, full control over your data.

Independently verifiedLast checked: June 15, 2026

Trello popularized kanban-style project management, but at $5/month ($60/year) for the Standard plan, it competes with free alternatives. Planka is an open-source kanban board with a clean interface. Wekan is another self-hosted option. For personal use, Trello's free tier (10 boards) is often sufficient. GitHub Projects is free and integrates with code repositories. The kanban concept is simple and well-implemented in many free tools — columns, cards, labels, and due dates are standard features everywhere.

Open-source alternatives give you something subscription software never can: the ability to inspect, modify, and self-host the code. This means full transparency, no vendor lock-in, and the freedom to run the software on your own terms. The following open-source alternatives have been evaluated for features, community health, and long-term viability.
