Frequently asked questions
Is Lazyweb a free Mobbin alternative?
Yes, Lazyweb is a free Mobbin alternative for people who want a design reference library with real screenshots, flows, and product patterns.
Why is Lazyweb free?
We want to increase access to great designs. Design research should not be expensive just because screenshots are organized; anyone can collect screenshots themselves. Mobbin and Refero are great, but there should also be a strong free alternative, and that is what Lazyweb provides.
How big is Lazyweb's design library compared to Mobbin and Refero?
Lazyweb has 281,000+ screenshots. That is almost double Refero's public 130,000+ screen count and smaller than Mobbin's public 621,500+ shipped-screen library; roughly 40% of Mobbin's current public count.
What kind of screenshots does Lazyweb have?
Lazyweb has real marketing-page screenshots and iOS app screens, including paywalls, onboarding, checkout, pricing, signup, settings, retention, and product-flow references.
Does Lazyweb have flows?
Yes, Lazyweb has flows. You can use them to study complete user journeys instead of only looking at one isolated screen.
Does Lazyweb have web apps?
No, Lazyweb does not currently focus on web app screenshots. We have marketing pages and iOS apps, and web apps are top of mind.
What is a design reference library?
A design reference library is a searchable collection of real product screenshots, flows, and UI patterns that helps teams understand how strong products solve common UX problems.
How can founders and product teams use Lazyweb for design research?
Founders and product teams can use Lazyweb to compare real examples, find UI inspiration, benchmark competitors, and turn design research into clearer product decisions without starting from a blank page.
