I Built a Zero-Backend Kanban Board with React + TypeScript — Here's What I Learned

No server. No database. No login. Just pure React — and it actually works great.

Why I Built KanbanFlow

Every Kanban tool I used asked me to sign up, connect to a server, or pay for features I didn't need. I wanted something that just opened and worked — instantly, privately, offline.

So I built KanbanFlow — a fully-featured Kanban board that lives entirely in your browser. No account. No backend. No setup.

Unlimited columns and tasks — fully customizable

Drag & drop task movement across columns

Priority tagging — High, Medium, Low, None

Due dates with overdue highlighting
