## What it is
Kan is an open-source, self-hostable kanban project management application positioned as a Trello alternative. It offers boards, cards, labels, comments, activity logs, templates, team collaboration, and Trello imports, built with Next.js, tRPC, Drizzle ORM, and Better Auth.

## Use cases
- self-host a Trello alternative for my team
- manage tasks on a kanban board
- import my existing Trello boards
- collaborate with teammates on project boards
- track card changes with an activity log
- create reusable board templates for recurring workflows
- host project management software on my own infrastructure

## When to choose
- you want a minimalist, Trello-style kanban app you can self-host
- you need full data ownership of your project management data
- you want to migrate away from Trello with easy board imports
- you prefer open-source tooling built on a modern TypeScript stack

## When to avoid
- you need advanced reporting, Gantt charts, or enterprise project management features
- you require mature third-party integrations (still marked as coming soon)
- you need SAML SSO or custom branding without the paid cloud plans
- you want a native desktop or mobile app rather than a web application
