Mobbin

Mobbin is a reference library of real product interfaces. It captures shipped apps — full flows, not isolated screens — across mobile and web, and makes them searchable by app, by pattern and by element. You can pull up thirty onboarding flows and see how teams that already ran the experiments solved it.

It is in active use here. We open it before drawing anything: onboarding, empty states, settings, upgrade prompts. The job it does for us is stopping us reinventing a solved pattern badly. Ten shipped versions of the same screen tell you which decisions are conventional and which are the two or three you genuinely have to think about.

Dribbble and Behance are the alternatives for visual inspiration, but they show concepts rather than shipped software, so the constraints that shaped the real thing are missing. Page Flows covers similar ground with recorded walkthroughs, which is better when timing and transitions matter. Land-book and Godly are narrower and stronger if you only care about marketing sites. Refero is worth keeping as a second source. Mobbin is the right call when you need to see how real products handle a specific flow. It is the wrong call if you treat it as evidence — what other teams ship is a starting point, not research into your own users.
