Mobbin

Mobbin is a searchable reference library of user interface screens captured from real, shipped mobile and web apps. Instead of mockups or concept art, you browse actual screens that products have published — onboarding flows, paywalls, settings pages, checkout steps, empty states, and everything in between. The site currently lists 621,500 screens, with new ones added every week.

The library draws from a wide range of products. The homepage highlights apps like Airbnb, Notion, Spotify, Duolingo, Linear, ChatGPT, Shopify, Coinbase, Nike, Headspace, Threads, Wise, and PayPal, alongside smaller indie tools. You can browse by app, by UI pattern, or by platform, which makes it useful for answering specific questions — say, how several fintech apps handle identity verification, or what a modern empty state looks like in a productivity tool.

Signup is free, with paid plans available for people and teams that need more. Mobbin also maintains a dedicated MCP (Model Context Protocol) page, reflecting its positioning for AI agents as well as human designers — the hero line reads "Where teams and agents find designs that work." The company also runs a YouTube channel and an X account for design breakdowns and updates.

• Developers who want to match a familiar, proven UI pattern

• Teams preparing competitive teardowns or design audits
• Developers connecting AI agents to the library through MCP
