Basic board

The slim core board — shapes, sticky notes, text, frames, edges, images and freehand ink, with no rich-text editor and zero BlockNote peers.

Opt-in

Rich text

The same board with BlockNote block-editor nodes added through the spatialboard/blocknote entry point.

Extend

Custom nodes

Three custom node types wired into a live data-flow graph — typed ports and a pure compute function, recomputing as you drag.

Everything

Playground

The development app: every feature, around forty custom node types, plus the Whiteboard, Half adder, Deck and Mission Control boards.
