An infinite whiteboard that stays on your machine
Bracepad Canvas is a free, offline-capable drawing surface for sketches, diagrams and infinite-canvas notes. Pick the pen and draw; pick a shape and drag one out. Shapes are drawn in a hand-sketched style, so a quick diagram looks deliberate rather than unfinished. Nothing is uploaded, there is no account, and the board keeps working with the network off.
Is this an Excalidraw alternative?
It is built on the same two open-source libraries that give Excalidraw its
look and feel — roughjs for the hand-drawn shapes and
perfect-freehand for the stroke physics — without the editor
being a fork of it. The scene model is deliberately Excalidraw-shaped so
files can move between the two; import and export land with the export
work.
Can I use it from the keyboard?
Yes. V, H, P, R, O, D, L and A pick tools; N steps through the shapes on the board; arrow keys nudge the selection or pan the view; +, -, 0 and 1 handle zoom; G toggles the grid. Tab is deliberately left alone so you can always leave the canvas.
Can I put text or a table on the board?
Not yet. When it arrives, a text box on the canvas will be a real Bracepad editor — the same blocks, markdown shortcuts and keyboard shortcuts as the page editor — rather than a second, weaker text engine.
