Infinite canvas

Pan and zoom smoothly across an unbounded space using world-space coordinates.

Built-in tools

Freehand drawing, shapes, text, eraser, and selection — everything you need to think visually.

Local-first by design

No telemetry, no sync, no servers. Your boards live entirely on your machine.

Why Uboard?

Uboard is for people who think spatially. It stays out of your way, launches instantly, and gives you a calm, private space to work through ideas visually.
