Design Systems Surf is a searchable database of design systems from real companies, currently covering 65+ systems with thousands of individual component and pattern-page links.
Rather than linking to just the homepage of each design system, it indexes down to the component and directory level, so a search for a specific pattern (like a date picker or empty state) can surface the exact page across dozens of systems that document it.
Designers researching how many different companies solve the same specific UI problem, rather than browsing one system end to end.
The component-level search is the reason to use this over a general directory like Adele or Design Systems Repo. Reach for it when hunting a specific pattern, not for a broad overview of one company's system.
Database of best-in-class design systems.
