PLANKA

PLANKA is a kanban board in the style of Trello. It is built by PLANKA Software GmbH, based in Kempten, Germany. Teams organise work into projects, boards, lists and cards, and changes sync in real time over WebSockets. Cards support Markdown descriptions, comments, attachments, labels, due dates, checklists, custom fields and a stopwatch. The source code is visible and published under a fair-code Fair Use License for the free Community edition. Paid editions use a commercial licence, so PLANKA is not open source in the OSI sense. The Community edition costs nothing apart from your own hosting. Pro Self-Hosted costs EUR 7.90 per user per month, or EUR 7.20 per user per month on annual billing. Pro Hosted costs EUR 9.40 per user per month, or EUR 8.50 on annual billing, with a 5-user minimum. Hosted instances are dedicated, run in Germany, and come with a GDPR data processing agreement. Pro adds the mobile app, calendar, timeline and map views, recurring cards, templates, Worker and Guest roles, branding, OIDC single sign-on, and a dashboard with exports. Enterprise pricing is custom and starts at 1,000 self-hosted or 500 hosted users. For integrations, PLANKA offers a REST API, webhooks, and notifications through more than 100 providers. It has nothing comparable to Trello Power-Ups or a broad app marketplace. It suits privacy-minded small teams, IT departments and European organisations that want a simple board under their own control. Its main limitation is scope. Independent reviewers note there are no automation rules, no Gantt charts and no swimlanes, and self-hosters must handle their own backups and upgrades.
