## What it is
Fizzy is an open-source Kanban board application by 37signals for tracking issues, bugs, ideas, and small projects. It is built with Ruby on Rails and Hotwire, and can be self-hosted via Docker or Kamal.

- track ideas and small projects across a team
- replace bloated tools like Trello or Jira with a lightweight kanban app
- publish a public board so anyone can follow progress
- send card updates to Slack or Campfire via webhooks
- customize an open-source kanban tool to fit my workflow

## When to choose

- you need public boards, webhooks, and auto-cleanup without enterprise bloat
