Kanboard

A Kanban project board that keeps tasks in columns you define, with swimlanes for parallel work, subtasks, comments, and an activity trail on every card. It includes automatic actions that move tasks or trigger webhooks when rules match, plus an API and a plugin system for custom reports, and the interface stays deliberately plain and keyboard friendly.

Small teams use it for sprint boards, issue triage, and personal task lists without the ceremony of a larger project suite.

Running it yourself keeps your backlog inside your network, with no per-user charges and one database that is easy to snapshot.
