Lookup.design is a small, handpicked library of UI component examples — around 900 images from 40+ well-designed brands, hand-named and categorized rather than auto-tagged, with roughly 100 new examples added each month.
Because everything is manually indexed instead of scraped, the tagging is unusually precise — you can search for a specific component type and reliably get relevant results instead of wading through mistagged screenshots.
Good for designers who want a smaller, higher-signal alternative to huge auto-aggregated screen libraries — quality of curation over sheer volume.
At under 1,000 images total, it's a much smaller library than Mobbin or Inspireca — great for quick, high-quality reference, but you'll run out of new material in a given category fairly quickly.
