Inspiration

I often needed a lightweight task management tool — something faster and simpler than traditional project tools. Most solutions felt bloated or required sign-ups. So I built banban, a minimalist, local-first Kanban board that just works out of the box.

What it does

banban lets you create multiple boards, each with columns and draggable cards. You can add/edit/delete cards, organize them across columns, and everything is saved locally in your browser. It supports light/dark mode, has a clean, responsive UI, and requires no login or backend setup.

How we built it

We built banban as a browser-based SPA using modern web technologies (details omitted). Key features include:

A structured state model for Workspace → Board → Column → Card

localStorage for instant persistence

Drag-and-drop interactions for cards and columns

A minimal UI system inspired by Vercel and Linear, with responsive layout and dark mode toggle

Challenges we ran into

Designing a scalable yet simple local data model without a backend

Making drag-and-drop smooth and intuitive across multiple levels (columns ↔︎ cards)

Handling reactivity and UI state updates when cards move or get edited

Balancing minimalism with enough functionality to be useful

Accomplishments that we're proud of

  • Fully functional board + card system with no backend
  • Smooth user experience using only browser-native storage
  • Launch-ready responsive UI that feels professional and fast
  • Building something people could use immediately — with zero setup

What we learned

  • Designing local-first apps forces you to think about offline resilience and user state
  • Even without a backend, it’s possible to build polished tools that feel responsive and useful
  • Simplicity takes work — removing features can be harder than adding them

What's next for BanBan

  • Add keyboard shortcuts and card checklist support
  • Add import/export options for backup
  • Potential Firebase or Supabase integration for multi-device sync
  • Collaborator support for shared boards
