Why tldraw

  • Custom geometry, custom UI

    Every shape and tool is replaceable. Add walls, ducts, beams, fixtures, even component families. The canvas is yours.

  • Clouds included

    We learned from the best: the cloud shape is a must-have in a world of eternal angles. So we added it for you.

  • Precision drawing primatives

    Snapping, alignment, measurement, and a coordinate system designed for technical work. Build BIM, MEP, and fully generative design.
