KanbanTab
The secure, offline-first Kanban board that lives in your browser. Designed for speed, seamless sync, and absolute data ownership.
Open AppExtreme Speed
Built with a "Local-First" architecture. KanbanTab loads instantly and responds in milliseconds because your data lives on your device, not just in the cloud.
Encryption by You
Enable optional end-to-end encryption to protect your data with a personal passphrase. We don't have the keys, making your boards unreadable to anyone else.
Work from Anywhere
KanbanTab works flawlessly without an internet connection. Use it on a plane, in a tunnel, or a remote cabin. Your changes sync automatically the moment you reconnect.
The KanbanTab Manifesto
We believe productivity tools should be invisible, fast, and fiercely private.
Data Sovereignty
Your data belongs to you. It stays on your machine by default, and you decide when it gets synced.
Zero Latency
Every millisecond of waiting is a distraction. We optimize for zero-wait interactions and instant feedback.
Subpoena-Proof
By using client-side encryption, we make it mathematically impossible for third parties to seize your data.
Free forever for local use.
