Kanboard

Kanboard is a free, open source Kanban project management application written in PHP. It focuses on simplicity and a minimalist interface for visualizing work, limiting work-in-progress, and moving tasks across columns via drag-and-drop. The platform is designed to deliver a no-training-required experience for teams that want the core Kanban methodology without feature bloat — a notable contrast to commercial tools that bundle every workflow concept into a single workspace.

The software includes tasks and subtasks, attachments, comments, swimlanes, time tracking, project analytics, and a flexible query language for searching and filtering the board. Event-based automatic actions let you automate repetitive workflows such as moving tasks, changing assignees, or applying categories based on triggers. Kanboard supports LDAP/Active Directory plus OAuth2 providers like Google, GitHub, and GitLab for authentication, ships a JSON-RPC API and webhooks, and is translated into more than 30 languages.

Kanboard is published under the MIT license and self-hosted as a PHP application backed by SQLite, MySQL/MariaDB, or PostgreSQL. Docker images and official packages for Debian, Ubuntu, and RHEL are available, and a large plugin ecosystem extends it with notifications, Gantt charts, calendar views, custom themes, importers from Trello and Jira, and dozens of other additions. The core author considers the project in maintenance mode, so new major features come primarily from community contributions and plugins — making the plugin directory the primary way to grow the platform beyond its intentionally lean core.
