The challenge

A design file is a picture, and the product moves on without it. Design tools hold drawings, feedback tools hold screenshots, and nothing holds the running product itself, so notes like "the button on the left" land on the wrong component. CRABZLAB started as the review board for our own products, Goldmarket first, and grew into a tool of its own.

01

The running product on one canvas.

Every route of a live build, captured on real devices and laid out side by side, with up to twelve screens live at once.

02

Point at anything, it knows what it is.

Hover names the element, a click pins a comment that carries the component, its box and its route.

03

Every way to look at a product.

Eight pages from the same captures: screens, flows, scenarios, sitemap, design system, responsive, moodboard and branding.

04

One button, a documented product.

Optimize reads the product behind the screens and writes its sitemap, flows and design system in one step, with one Undo.

05

A brief, not a guess.

Send to iterate writes a precise brief for the coding tool the team already uses, on their own machine, and the screens catch up.
