Planka

PLANKA is a self-hosted Kanban board built for teams that want full control over their project data without paying per seat or depending on a third-party cloud. It's a direct alternative to tools like Trello, designed to run on your own infrastructure while still feeling polished and modern.

The free Community Edition covers the core use case well:

• Unlimited boards and cards with no artificial limits tied to pricing tiers
• Real-time synchronization so every team member sees updates instantly without refreshing
• 35+ languages supported, making it practical for international teams
• Docker-based deployment with a large base of pulls (8M+) showing it's widely used in production
• GDPR compliance baked in, since you own and host the data yourself

For teams that need more, the Pro Edition adds higher scalability, additional professional features, and priority support. Both editions are available as self-hosted installs or through PLANKA's managed cloud hosting if you'd rather skip the infrastructure work.

Compared to other self-hosted options like Wekan or Focalboard, PLANKA puts a stronger emphasis on visual design and ease of use. It doesn't try to be a full project suite with Gantt charts and resource planning. It stays focused on the Kanban workflow, which keeps the interface clean and the learning curve low.
