πŸ“Š 37signals Unveils Fizzy: Open-Source Kanban Tool Challenging Trello and Asana with Free Hosting

37signals has launched Fizzy, an open-source kanban application designed to provide a streamlined, visually engaging experience for managing tasks including bugs, issues, ideas, and small projects. Positioned as a fast, straightforward alternative to established tools like Trello, Jira, and Asana, Fizzy emphasizes simplicity with a vibrant interface.

Enhanced Kanban Workflow πŸ—‚οΈ Beyond standard kanban functionality, Fizzy incorporates practical features like automatic closure of old cards to prevent board clutter, webhooks for sharing updates with Slack or Campfire, and notification stacks for efficient review. When cards receive no activity, the system surfaces relevant information to help teams maintain momentum and address neglected items.

Transparency and Attribution The platform supports public board creation for broader visibility and displays stamps showing submission detailsβ€”who created each card and when. This attribution mechanism improves accountability and communication within collaborative environments.

Flexible Deployment Options βš™οΈ Fizzy is available as free, open-source software for organizations preferring self-hosted deployments with complete control over data and infrastructure. For teams seeking managed solutions, 37signals provides a hosted version with generous free-tier allowances.

Generous Free Tier πŸ’° The hosted offering enables teams to track up to 1,000 cards at no cost, with no restrictions on user count or time limits. This removes common freemium barriers that cap team size or impose trial periods, making Fizzy accessible for small teams and startups.

Scalable Pricing Structure Organizations requiring capacity beyond 1,000 cards can upgrade to unlimited card tracking for $20 monthly. Storage allocations include 1 GB on the free plan and 5 GB with the paid tier, with additional storage available in 50 GB increments for purchase.

This release continues 37signals' tradition of creating opinionated productivity tools with clear pricing models, while the open-source nature differentiates Fizzy from proprietary competitors by offering deployment flexibility and transparency that appeals to privacy-conscious organizations and technical teams.
