Open Source Kanban Boards

What Is a Kanban Board

A Kanban board is a visual tool for managing work as it moves through a defined process. Columns represent stages of the workflow, such as "To Do," "In Progress," "Review," and "Done." Cards represent individual work items that move from left to right as they progress through each stage. Work-in-progress (WIP) limits restrict how many cards can occupy a column at the same time, which prevents team members from taking on too much work simultaneously and helps identify bottlenecks when cards pile up in a particular stage.

The Kanban method originated in Toyota's manufacturing system in the 1940s and was adapted for knowledge work in the 2000s by David J. Anderson. It differs from Scrum in that it does not use time-boxed iterations (sprints). Instead, work flows continuously, with new items pulled into the process as capacity becomes available. This makes Kanban particularly suitable for teams with unpredictable workloads, such as support teams, operations teams, and agencies that handle client requests on an ongoing basis.

Digital Kanban boards add features that physical boards cannot provide: filtering and search, automated actions when cards change status, time tracking, integration with development tools, and the ability for distributed teams to collaborate on the same board in real time. Open source Kanban tools offer these capabilities with the added benefits of self-hosting, data ownership, and zero licensing costs.

Dedicated Kanban Board Tools

Kanboard

Kanboard is a minimalist, self-hosted Kanban application built on PHP. Its philosophy is that simplicity drives productivity, and the interface reflects this by avoiding feature bloat. Boards have customizable columns with optional WIP limits. Cards support subtasks, comments, attachments, due dates, color coding, and time tracking. Automated actions trigger events when cards are moved, created, or modified, enabling workflows like automatically assigning a card to a specific user when it enters the "Review" column or sending a notification when a deadline is approaching.

Kanboard integrates with external services through plugins and webhooks. Official integrations include Slack, GitLab, Bitbucket, Mailgun, and Postmark. The plugin system supports LDAP authentication, custom themes, S3 file storage, and calendar views. The REST and JSON-RPC APIs enable custom integrations and automation scripts.

Deployment is straightforward because Kanboard runs on any standard PHP hosting environment. It supports SQLite for small installations (requiring no separate database server), MySQL, and PostgreSQL for larger deployments. Docker images are available for containerized deployments. The entire application is lightweight, running comfortably on a server with 512 MB RAM, making it one of the most resource-efficient options available. Kanboard is licensed under the MIT license, giving organizations maximum flexibility in how they use and modify the software.

WeKan

WeKan is a privacy-focused, open source Kanban board that positions itself as a self-hosted alternative to Trello. Built on Meteor (a full-stack JavaScript framework) with MongoDB as its database, WeKan offers a richer interface than Kanboard with features like multiple board views, swimlanes for horizontal categorization, checklists within cards, card labels and members, due dates with calendar integration, and board templates for repeatable workflows.

Access control in WeKan is granular, with board-level permissions that control who can view, comment on, or edit cards. This makes it suitable for organizations that need to share boards with external collaborators while restricting sensitive information. WeKan supports LDAP authentication for organizations with existing directory services, and it offers OIDC (OpenID Connect) integration for SSO deployments.

WeKan is available as a Snap package for Ubuntu, which simplifies installation to a single command. Docker images and Sandstorm packages are also available. The Snap deployment includes automatic updates, making WeKan one of the easiest Kanban tools to install and maintain. The resource requirements are moderate, with MongoDB and the Meteor application running well on a server with 1 to 2 GB RAM. WeKan is licensed under the MIT license.

Planka

Planka is a newer open source Kanban board built with React and Node.js, using PostgreSQL as its database. It offers a clean, modern interface with real-time updates, card comments and attachments, member management, board backgrounds, and markdown support in card descriptions. Planka focuses on being a straightforward Trello alternative without the complexity of a full project management suite.

The project is actively maintained and growing in adoption. Docker is the primary deployment method, with a Docker Compose file that sets up the application and PostgreSQL database. Planka's interface is responsive and works well on mobile devices, which is useful for teams that need to check board status away from their desks. The visual design is polished and modern, which can help with team adoption since people are more likely to use a tool they find pleasant to interact with.

Kanban Views in Full Project Management Platforms

Taiga

Taiga's Kanban implementation is one of the most polished available in any project management tool, open source or otherwise. Boards support customizable columns, WIP limits per column, card filtering by assignee, label, or status, and card aging that visually indicates how long a card has been in its current column. Swimlanes provide horizontal categorization for organizing work by team, priority, or any other grouping that makes sense for your workflow. Taiga also offers a dedicated Scrum board for teams that practice sprint-based development, so you can run both methodologies within one project.

Plane

Plane includes a Kanban board view that organizes issues into customizable columns with drag-and-drop card movement. The board supports grouping by status, priority, label, assignee, or any custom property. Plane's board is tightly integrated with its cycle and module features, so you can filter the board to show only issues in the current cycle or a specific module. The interface is fast and visually clean, with inline editing and keyboard shortcuts for rapid triage.

OpenProject

OpenProject provides board views as a configurable layer on top of its work package system. A Kanban board is created by defining a board query that groups work packages by status, assignee, version, or any custom field. This query-driven approach is flexible, allowing you to create multiple board views of the same data with different filters and groupings. The trade-off is that configuration requires more upfront work than dedicated Kanban tools, which provide sensible defaults out of the box.

Key Features That Differentiate Kanban Tools

When evaluating open source Kanban boards, several features separate basic implementations from tools that genuinely support the Kanban methodology. WIP limits are the most important, because without them, a Kanban board is just a task list with columns. Kanboard, WeKan, and Taiga all support column-level WIP limits that alert or prevent users from adding cards beyond the defined threshold. This enforcement is what makes Kanban work as a flow management system rather than just a visual organizer.

Card aging provides visibility into stalled work. Taiga implements this with visual indicators that darken cards the longer they sit in a column without updates. This makes it immediately obvious during a team standup which items are stuck and need attention. Not all tools support this natively, but it is one of the most useful features for teams practicing Kanban seriously.

Swimlanes add a horizontal dimension to the board, letting you categorize cards by team, priority class, service level, or any other grouping. WeKan and Taiga both support swimlanes natively. Kanboard achieves a similar effect through its project grouping features. Swimlanes are particularly valuable for teams that handle multiple types of work on a single board, such as an engineering team managing feature development, bug fixes, and infrastructure tasks simultaneously.

Choosing Between Dedicated and Integrated Kanban

The decision between a standalone Kanban board and a Kanban view within a larger project management platform depends on your team's needs. Dedicated tools like Kanboard, WeKan, and Planka are ideal for teams that want a focused, lightweight solution without the overhead of features they will never use. They deploy quickly, require minimal resources, and have intuitive interfaces that new team members can learn in minutes.

Integrated Kanban views within platforms like Taiga, Plane, or OpenProject make more sense when you need the Kanban board to coexist with sprint planning, documentation, time tracking, or cross-project reporting. The board becomes one view of data that is also accessible through timelines, backlogs, and list views. This integration eliminates data duplication and ensures that updates in one view are immediately reflected in all others.

For teams that are unsure, start with a dedicated tool. It is easier to migrate from a simple Kanban board to a full project management platform than to simplify a complex deployment that your team has outgrown. Kanboard and WeKan can both export data that other tools can import, so you are not locked into your initial choice.
