Planka

Planka is a self-hosted Kanban project tracker for teams. Users create projects, boards, lists and cards and move tasks around with drag and drop, while changes appear for collaborators in real time. Its repository topics position it as an alternative to Trello.

The Community edition includes Markdown cards with comments, attachments and custom fields, along with real-time collaboration, a stopwatch, due dates, notifications through more than 100 providers, webhooks, a documented REST API and two-factor authentication. PLANKA Pro, aimed at organizations, adds phone and tablet apps, themes, calendar, timeline and map views, templates, cards on multiple boards, guest roles, OIDC single sign-on and PDF export.

Both editions are self-hosted, so you keep your own database and backups, and Docker is the usual way to run them. A Pro upgrade converts an existing Community installation in place, but it is a one-way migration, so a backup is recommended. A cloud option is also linked. The repository lists its licence as Other.
