How it all started?

Over my 15 year design career, I've spent countless hours manually inspecting websites with DevTools: 1-3 hours per brand plus additional benchmarking sites.

Designers struggle to dissect brands from websites, and it's not just about extracting colors. The real challenge is understanding what truly matters in a brand system.

Dembrandt helps the designer-dev-business workflow. It saves me hours every week. Just dissect the brand with 1 command and use the design tokens in your preferred design systems.
