Planka

Trello's board model on your own server: Planka is an open-source Kanban project management tool. Boards organize into projects with lists, cards, labels, due dates, checklists, file attachments, and per-card stopwatch time tracking, all managed through drag-and-drop. Updates propagate over WebSockets, so a teammate moving a card or adding a comment appears instantly for everyone without a refresh - a genuine differentiator among self-hosted boards. Card descriptions use a full Markdown editor, custom fields adapt cards to your workflow, and views switch between Kanban, grid, and list layouts. Authentication supports OpenID Connect single sign-on with Google, Azure AD, Okta, or any OIDC provider - a feature Trello reserves for enterprise plans - and notifications reach 100+ channels including Slack, Discord, Telegram, and SMTP via Apprise. A REST API with 50+ webhook events supports custom integrations, and one-click board import eases migration. Built with React and Node.js on PostgreSQL, translated into 35+ languages, deployed via Docker.

Benefits

  • Trello's Core Without Per-Seat Costs
  • Trello's free tier caps at 10 boards and paid plans run $5-10 per user monthly. Planka offers unlimited boards, cards, and users for the cost of hosting.
  • Real-Time That Actually Works
  • WebSocket sync shows card moves and comments instantly across all connected users, unlike self-hosted alternatives that need manual page reloads.
  • SSO Without Enterprise Pricing
  • OIDC single sign-on with Google, Azure AD, Okta, or Authentik ships in the free self-hosted edition - a capability most hosted boards lock behind enterprise tiers.
  • Project Data Stays Private
  • Task boards expose roadmaps, clients, and internal priorities. Self-hosting keeps them on your server with no tracking or third-party access, simplifying GDPR compliance.
