About

Gummble is a UI design reference library with more than 300,000 real app screenshots, 21,000+ user flows, and design patterns from 1,500+ shipped iOS, Android, and web products. Designers, UX researchers, developers, and product teams can search by pattern, such as onboarding, paywalls, empty states, and settings; by UI copy; or by complete flows. Each screen includes design analysis, and users can save references to collections. Its MCP server lets compatible AI assistants and coding tools, including Claude, Cursor, and Codex, search the library to ground interface design and implementation in real product examples. The free plan offers limited browsing; Browse adds unlimited screens, flows, downloads, collections, and MCP access, while Pro adds Figma export.
