Mobbin
UI/UX reference library: hundreds of thousands of real mobile and web app screens, cataloged and searchable by pattern (onboarding, paywall, settings, search). You find how the best apps solve a screen, hand the screenshot to your AI and ask it to take inspiration. You can also skip the screenshot: Mobbin publishes an official MCP server hosted at https://api.mobbin.com/mcp, nothing to install (you sign in with your account), and your agent searches screens itself, flows such as onboarding or checkout, and site sections such as a pricing page.
Strengths
- Hundreds of thousands of real screens, searchable by flow and pattern
- Concrete reference to hand the AI rather than a vague prompt to make it pretty
- Covers mobile AND web, from onboarding to paywall
Limitations
- Full search behind a paid subscription
- Coverage biased toward US consumer apps
Best for
- PMs, POs and designers who want to reference a proven pattern before having it generated
- Vibe coders who want their screen to look like a real app, not a generic mockup
