Fizzy is a new Kanban-based project management tool that offers a modern, colorful interface for tracking work items across columns. Available both as a managed SaaS ($20/month after 1,000 free cards) and for free self-hosting, it uses the O'Saasy License which allows anyone to run their own instance while reserving commercial SaaS rights to the creators. The entire codebase is publicly available on GitHub, built with Rails, and designed to allow data portability between self-hosted and managed instances.
