What is Fizzy?

Fizzy is a kanban tool from 37signals, the company behind Basecamp and HEY, for tracking bugs, issues, ideas and small projects as cards on boards. Cards left untouched are closed automatically after a set number of days, and an urgent card can be marked as a Golden Ticket that moves to the top of its column. The hosted service is free, and the source code is published for running on your own server.

Fizzy is free to use. See every plan

Good for

  • Small teams tracking bugs, issues and ideas on simple boards
  • Teams that want a hosted kanban tool with no per-user fee
  • Developers who want to run or modify the code on their own server

Worth knowing

  • The hosted service limits file storage to 1 GB. The iOS app is for iPhone only, and desktops use the browser or an installed web app.
  • There is no import from Trello, Jira, GitHub Issues or Basecamp and no two-way integration; data leaves through webhooks and the API.
  • Cards cannot be reordered within a column, the three default columns cannot be renamed, and there are no board or card templates.
  • The O'Saasy license permits self-hosting and modification but bars offering the software to others as a competing hosted service.

Key features

Boards and columns
Every board starts with three columns, NOT NOW, MAYBE? and DONE. Custom columns, each with its own name and color, are added alongside them.
Cards with steps and comments
A card holds a description, a checklist of steps, comments, tags and an assignee. Typing # in a card links to another card by its number.
Auto close
Cards with no activity move to NOT NOW after a set period, 30 days by default. Administrators can change the period for the account or for one board.
Golden Tickets
Marking a card as a Golden Ticket turns it gold and moves it to the top of its column, which is how urgent work is prioritized.
Public boards
A board can be given a public link so that people outside the account can follow its progress.
Webhooks and API
Webhooks send board events, such as a card being created, assigned or completed, to Slack, Campfire or any tool that accepts them. An API covers boards, cards and comments.
