Prototyping

The fastest way to sketch a screen flow on a shared whiteboard that anyone can jump into and edit live, no signup required.

Other products from Prototyping

Basically the default for mocking up screens and wiring them into a clickable prototype your team can actually poke at.

Skips the mockup-then-rebuild cycle entirely — drag out a design and it's already a real, interactive site.

Turns a text prompt or a phone photo of a napkin sketch into editable screens when you need a mockup faster than opening Figma.

Deliberately ugly, hand-drawn-style wireframes that keep stakeholders arguing about layout instead of button colors.
