Fizzy is a fast, self-hosted Kanban alternative to Trello featuring automated card pruning, signed outbound webhooks, and zero per-seat subscription fees.
Fizzy runs on a vanilla Ruby on Rails stack backed by Hotwire, delivering a server-rendered Kanban board that bypasses heavy client-side build steps. Published on GitHub with its complete development history of over seventeen hundred pull requests, the project pairs containerized self-hosting with automated card lifecycle management. It provides visual issue tracking without frontend framework overhead or recurring per-seat fees.
Trello relies on its Power-Up ecosystem to connect outside tools, introducing third-party permissions, paid add-ons, and automation caps on entry tiers. Fizzy handles connectivity through direct outbound webhooks signed with HMAC-SHA256 headers. When cards are created, assigned, triaged, closed, or auto-postponed, Fizzy dispatches an event payload directly to your chosen endpoint, including Campfire rooms, Slack channels, or internal brokers. Operations leads can wire board events directly into build runners without routing data through external middleware.
That simplicity carries architectural trade-offs. Trello offers turnkey connectors, two-way sync integrations, and visual automation builders. Fizzy deliberately omits plugin marketplaces, pre-built synchronizers, and native board importers from Trello or Jira. Ingesting tasks or syncing statuses requires writing against Fizzy's personal-access-token REST API or calling its CLI. For teams wanting lean boards that announce lifecycle changes via clean webhooks, Fizzy removes integration layers; for organizations that depend on click-to-install SaaS integrations, building custom connectors requires engineering time.
Fizzy vs Trello — which fits a small team best? Trello suits organizations that rely on commercial plugin marketplaces and visual automation builders, while Fizzy is ideal for teams wanting a self-hosted, lightweight board with direct webhooks and no subscription fees.
Can I self-host Fizzy on my own server? Yes. 37signals supplies official Docker images and Kamal deployment configurations for standard Linux servers.
Does Fizzy offer two-way integrations with Jira or GitHub? No. Fizzy supports outbound signed webhooks and a REST API with personal access tokens, but offers no native two-way sync or plugin marketplace.
Fizzy is a strong match for teams that want an unencumbered visual board tied to internal systems via clean webhooks, provided they do not require third-party plugin directories or sprint planning matrices. Backed by active maintenance from 37signals with regular updates across 2026, the project distributes source code under O'Saasy terms that grant full freedom for internal self-hosting while restricting competing commercial cloud resale.
Lint, codegen, breaking-change checks and dependency management in one Git-native CLI. Open source, no registry lock-in.
