Overview

Fizzy is an open-source kanban product from 37signals for tracking anything from bugs and issues to ideas and small projects. It presents itself as a simpler, faster alternative to heavier issue and task trackers, with a focus on cards, columns, and an uncluttered workflow.

The product is positioned as fully free to use, with a 1 GB file-space limit noted on the site. It can be self-hosted, and the license allows modification and other forms of use with some restrictions on operating it as a competing hosted or SaaS service.

Features

Flexible kanban boards

Track bugs, issues, ideas, and small projects in a kanban-style board built to stay simple and fast.

Auto close

Use auto close to prune old cards so inactive items do not pile up indefinitely.

Webhook notifications

Send board events through Webhooks, including card creation, assignment, and completion.

Public boards

Publish a board publicly so anyone can follow along without needing access to an internal workspace.

Card stamps

See who filed what and when with stamps attached to cards.

Stacked notifications

Let notifications stack and fan open for easier access when there is activity to review.
