Mobbin alternatives: 8 UI libraries and what each one shows

Mobbin claims over 600,000 screens from real apps and websites, more than any library on this page claims, and its closest alternatives each win on one thing. Refero covers web and iOS and writes styles down as values. Page Flows records flows as video. Nicelydone and SaaSFrame go deep on SaaS. ScreensDesign records whole iOS journeys up to the paywall. Appshots has the cheapest lifetime plan, Spotted in Prod collects iOS motion, and Collect UI shows concept work.

Pick by the question you are asking. How does a real app handle this screen is a question for Mobbin or Refero. What happens between the screens is one for Page Flows or ScreensDesign.

There is a third question that none of the screen libraries answers well: what should the site that sells my app look like. A screenshot of a landing page leaves out the motion and every value behind it. That is where Thanor fits, as a different kind of tool, and the cards below show what it means in practice.

How this list was checked#

Every product was opened on its own site on 9 November 2026, and prices are quoted as each pricing page showed them that day. Two libraries showed euros to a European connection, and their dollar prices may differ; where that applies it is noted. For each one we recorded:

• what it shows: static screens, flows, or video recordings
• which platforms it covers: iOS, Android, web, marketing sites
• what the free tier allows, and what the paid plans cost
• how it reaches your tools: Figma, an MCP server or an API

Several names that still appear in older lists are gone or have merged into another product. They have their own section near the end, with the evidence. Thanor publishes this page and appears in it, and it is described with the same limits as the others.

What Mobbin does, and what it costs#

Mobbin is a library of real mobile apps, web apps and websites, browsable by platform, category, flow, screen pattern and UI element. Its changelog shows how fast it has grown in two years:

• February 2025: visual search and similar screens
• August 2025: Mobbin Sites, for landing pages, portfolios, shops and microsites, filtered by section and style
• November 2025: Animations, with screens captured as short videos
• August 2026: plain-language search, search for the text inside screenshots, and Deep Search

Screens can be saved to collections and copied into Figma on eligible plans. An MCP server for AI assistants comes with Pro, and the API with Team. At the time of writing there is no monthly billing. Pro is $10 a month billed yearly or $15 a month billed quarterly, Team is $16 per member a month billed yearly, and students get 50 percent off Pro.

One clause matters if your plan involves AI. Mobbin's terms say it claims no ownership of the designs in its screenshots, which belong to the companies that made them, and that you will not use AI or machine learning tools to create derivative works of content on the platform. That protects the app owners, which is fair, and it sets the use: research the pattern on Mobbin, then build from a specification of your own.

People look for an alternative for three reasons. The price is billed a year or a quarter at a time. They want flows as video rather than stills. Or the work is a marketing site rather than a product, where a screen library is the weaker tool.

The screen and the page are different jobs#

An app has two design problems. The product screens are onboarding, settings and checkout, where convention helps because users expect the pattern they already know. The page that sells the app is the opposite case: a landing page that looks like every other one is a page nobody remembers.

Mobbin and its alternatives are built for the first job, and so are generators of app screens such as GenDesigns. For the second, a screenshot is thin evidence. A marketing hero lives on things a still frame cannot hold: a mascot that tracks the cursor, a loop behind the headline, an entrance timed at 620ms on cubic-bezier(0.22, 1, 0.36, 1). Even Mobbin's Animations, which do capture movement, show it as a clip with no values attached.

The gap shows up the moment you brief a builder. Make the hero feel premium gives a model nothing it can measure. Two lines of values give it something to measure, and two runs come out close together:

Headline 72px on desktop, type ratio 1.25, ink #F4F1EA on #101014.
Entrance 620ms on cubic-bezier(0.22, 1, 0.36, 1), 80ms stagger.

Here is that second job done from a full specification, on two app sites:

Neither hero is a pattern you would find by searching for one. Each comes from an art direction written as values, which is the thing a screen library is not built to hand over. The SaaS website design examples go through more of these by technique.

The alternatives at a glance#

Eight libraries, plus Mobbin for reference and Thanor for the marketing site. Prices are at the time of writing.

Best for web and iOS with written styles: Refero#

Refero is the most direct substitute. It covers web and iOS products with static screens, complete user flows from sign-up to cancellation, and search by UI element. A Figma plugin inserts screens at their original size on paid plans, and an MCP server lets an AI assistant search the library.

What sets it apart is the styles section. Each style page offers a DESIGN.md with the colors in hex and the type sizes and line heights in pixels, for example a #0e0e0e canvas with a 36px headline at a line height of 1.1. Refero describes its styles as covering typography, color, layout, spacing, surfaces, components and imagery. Motion is not on that list.

From a European connection, the free tier shows about 3 percent of the collection. Pro is €10 a month billed €120 a year, or €15 a month billed €45 a quarter, a lifetime plan is €250, and students get 40 percent off. Its terms allow references in moodboards, presentations and Figma files, and forbid republishing them as a library.

• Choose Refero when you want written values next to the screenshots, or a one-time price.
• Stay on Mobbin when breadth matters more, especially across marketing sites.

Best for recorded flows: Page Flows and ScreensDesign#

Page Flows#

Page Flows records user flows as video, so you watch onboarding, upgrade and cancellation happen in order instead of reconstructing them from stills. It also has screens, UI elements and emails, across iOS, Android, web and email. Screenlane's old address now redirects here. At the time of writing it costs $99 a year, which works out at $8.25 a month, or $39 a quarter; a team plan covers three users for $199 a year. No Figma integration is mentioned on the site.

ScreensDesign#

ScreensDesign is iOS only and goes further down one path. Each app is a full recording from the first screen to after the purchase, with revenue estimates beside it, which makes it a paywall and onboarding research tool more than a general library. UI Sources and Design Vault both redirect here now. There is one plan, Full Pro, at $39 a month or $199 a year plus VAT where it applies, and it includes an MCP server.

Both answer the question a still screen cannot: what happens between two screens, and for how long. Neither turns that into values you can hand a builder, so the timing you watch is still timing you guess.

Best for SaaS products: Nicelydone and SaaSFrame#

Nicelydone#

Nicelydone covers web and SaaS apps only, with static screenshots, user flows and UI components from more than 500 SaaS products, marketing pages included. You can copy a screenshot straight into a Figma file, and a paid MCP is available. The free tier shows six screen previews. Paid Solo and Team plans are billed quarterly or yearly, with Team starting at two seats; the prices differed between its dollar pricing file and the euro page we were shown, so check them in your own currency.

SaaSFrame#

SaaSFrame is smaller and more hands-on. It holds SaaS website pages, product screens, flows and website sections, updated weekly, and its search reads the text inside screenshots. Some screens come with the page's Figma design, pasted as editable layers. The free tier shows three results per filter; Pro is $18 a month, $16 a month billed quarterly, or $15 a month billed $180 a year.

Pick Nicelydone for depth across products, SaaSFrame for editable Figma layers. Both are strong on the logged-in app and on the marketing pages of SaaS companies, which makes them good companions to the SaaS landing page prompt when you move from research to building.

Best for budget and niche: Appshots, Spotted in Prod and Collect UI#

Appshots#

Appshots covers iOS, Android and web, with more than 1,000 flows from over 400 apps, and its lifetime plan makes it the cheapest to keep for years. Pro is $16 billed monthly, $14 a month billed quarterly or $12 a month billed yearly, and a lifetime plan is $199. Teams are priced per team rather than per seat, at $429 a year for unlimited users, which is unusual in this category. Saving is a copy to the clipboard, with no named Figma integration.

Spotted in Prod#

Spotted in Prod collects short video clips of the best iOS interactions, prototypes included, and it was updated the day we checked. Its prices sit behind a sign-in, so they are left out here. It is the place to study how a sheet settles or a button springs back, frame by frame.

Collect UI#

Collect UI is a daily feed of designers' own shots grouped by category, recently including Liquid Glass, and it is free to browse. Remember that most of these are concepts rather than shipped products, so few of them have met real users.

Best for the site that sells your app: Thanor#

Thanor is a different kind of tool, and it belongs here for one reason: the day your app needs a marketing site, the screen libraries stop being the right reference. Thanor is a library of website designs, each shown as a live, moving preview, and each with a long, exact prompt. Paste the prompt into Claude, ChatGPT, Gemini, Cursor, Lovable, v0 or Bolt and the model builds that site.

The prompt is a full art direction written as values: the palette in hex, the type faces and scale, the spacing, the easing curves and durations, the section order and every interaction, plus hosted films, cut-outs and stills the page uses. Two more app and product heroes built that way:

Where Thanor is the wrong pick: it has no product screens, flows or paywalls, and it will never show you how Duolingo handles a streak. For that, use Mobbin or Refero. The Thanor MCP brings the library into Claude, ChatGPT or Cursor, much as Refero's and Mobbin's servers do for screens.

The libraries that closed or moved#

Old roundups still list these, and some still rank. Here is where each one stands.

If one of these was your reference, its successor in the table above is the nearest match: Page Flows for Screenlane, ScreensDesign for UI Sources.

How to choose a Mobbin alternative#

1. You need the widest set of real screens, apps and sites: stay on Mobbin.
2. You want written values next to the screenshots, or a lifetime price: Refero.
3. You want to watch a flow happen: Page Flows, or ScreensDesign for iOS paywalls.
4. You design SaaS products: Nicelydone for depth, SaaSFrame for Figma layers.
5. You want the lowest long-term cost, or a whole team on one price: Appshots.
6. You need the marketing site, not the product: Thanor, with Land-book or the Awwwards alternatives for breadth.

Whichever library you pick, the screenshots stop at the point where you have to decide the values yourself. Writing them down once as design tokens your AI can follow is what keeps the built product consistent with what you researched.

The verdict#

Mobbin is still the default for a reason: the largest claimed library, real products, websites since 2025 and short videos since late 2025. Refero is the best alternative for most people, with web and iOS coverage, a Figma plugin and style files that write color and type down as values. Page Flows is the pick when the flow matters more than the frame. Nicelydone and SaaSFrame suit SaaS teams, and Appshots suits a budget.

Choose the screen libraries if you are designing the product itself: onboarding, settings, a paywall, an empty state. That is their job, and they do it better than anything else on the web. Use two of them if you can afford it, one for stills and one for flows, because a pattern that looks right as a frame can still feel wrong in motion.

All of them answer what does this look like in a real product. None of them answers what should my own site look like and how should it move. That second question is the one that decides whether a launch page is remembered, and it needs values that a screenshot does not carry. Thanor answers it, for the marketing site and not the app, and the other prompt libraries are the place to compare it.

Open one app hero and move your cursor#

Open Judgy and move your cursor across the page. The alpaca's side-eye is a head-turn film driven by the pointer, and it is the clearest demonstration of what a screenshot library cannot hold. If you want to read a complete specification before choosing a plan, Vesperion is free with an account: copy its prompt and see every value a page like this is built from.
