Plane: an open-source platform for projects, cycles, and roadmaps

Plane brings work-item tracking, cycles, modules, pages, and analytics together in an open-source project management platform, with self-hosting options through Docker or Kubernetes. Its repository also documents a substantial architecture effort: migrating the interface to the Propel design system in stages, with tests, accessibility checks, and the gradual removal of legacy components. The web app uses React and React Router, with Django on the API side.
