Lazyweb vs UI Sources: Best UI Sources Alternative for Agentic Design Research

Lazyweb is the stronger pick when the job is giving an AI agent real product references, app-tree context, and screen-version history before designing — free, across 281k+ real app screens. UI Sources is the better choice when a human designer or founder wants to study how proven top-grossing iOS subscription apps handle onboarding and paywalls, with revenue and install context alongside the flows.

Honest Comparison Table

CriterionLazywebUI Sources
Best for Use Lazyweb when your AI agent needs to research real product patterns before designing. [24]Use ScreensDesign (formerly UI Sources) when a human designer or founder wants to study how proven top-grossing iOS subscription apps handle onboarding and paywalls, with revenue and install context alongside the flows. [1]
Pricing Free. [24]Paid — single "Full Pro" tier: $39/mo, $19/wk, $199 for 6 months (~$33/mo), or $399/yr (~$33/mo). Only the monthly AI Create credit allotment changes across periods. [1]
Library depth 281k+ real app screens across iOS apps and marketing pages. [24]~2,538 iOS apps, each captured as full end-to-end flow videos (onboarding, paywalls, App Store screens) annotated with estimated monthly revenue and installs. Smaller by raw count than the large screen libraries. [1]
Platform coverage iOS apps and marketing pages today; web-app flows are not available yet. [24]iOS-only for the core app library, plus a "Web Onboardings" section that captures the pre-install web funnels those mobile apps run. No Android, no general web/SaaS product flows, no email. [1]
MCP / API Agent-first MCP setup across Codex, Claude Code, Cursor, Antigravity, hosted Claude connector paths, and other agentic platforms. [24]No official MCP or public API (verified June 2026); /mcp, /api, and /docs all fall back to the homepage. Its "AI Create" generator hands off to coding agents but is not an agent-callable interface. [1]
Agent readiness Built for agents first, with skills that generate competitive analysis and large research reports. [24]Low for programmatic use: with no MCP server or API, an AI agent cannot query its screens, flows, or revenue data — a human must browse the web UI behind a Pro login. [1]

What UI Sources does well

  • Pairs full onboarding/paywall flow videos with estimated monthly revenue and installs — useful for benchmarking subscription apps, not just admiring visuals
  • Curated, full-journey video capture of top-grossing iOS apps organized by pattern (onboarding, paywall, permissions), plus an Animation Explorer
  • Captures the web onboarding/quiz funnels mobile apps run before install — a growth-focused angle most galleries skip
  • An "AI Create" generator turns researched patterns into first-draft screens and exports them for handoff to coding agents

Where UI Sources is limited

  • No official MCP server or public API, so AI coding agents cannot query the library directly — unlike competitors Mobbin and Nicely Done, which publish official MCP servers
  • iOS-only core library (plus those apps' web funnels); no Android, no general web/SaaS product flows, no email coverage
  • Smaller library by raw count (~2,538 apps) than screen libraries indexing hundreds of thousands of screens
  • No genuinely free working tier — logged-out browsing shows blurred screens behind "Unlock Pro," and real access starts at $19/week

Where Lazyweb shines

  • Free access makes it easy to start without buying a seat before research begins.
  • Agent workflows can pull references, app trees, and structured design context instead of relying on generic taste.
  • Screen-version history lets agents see how a real product's UI evolved over time, not just one snapshot.

Where Lazyweb is limited

  • Lazyweb does not yet have web-app flows; flows are mobile-first today.
  • Human-facing advanced filters are thinner than some paid human-first libraries.
  • The product is intentionally agentic-first, so purely manual browsing may feel less polished than specialist galleries.

What people say

Independent user feedback is thin and somewhat dated. The clearest signal is a Product Hunt page with just 2 reviews (4.5/5), where designers praise it as a useful inspiration library for studying real user journeys and the "user's POV" via screen-by-screen flows. Elsewhere it appears only as a brief, neutral line-item in "Mobbin alternatives" listicles, typecast as good for component-level pattern research. There is essentially no discussion on Reddit or Hacker News and no presence on G2, Capterra, or Trustpilot, so it lacks third-party validation. Concrete criticism centers on freshness: a reviewer flagged videos as unavailable, the library is widely called smaller and less current than Mobbin, and the brand's X account looks dormant.

What people praise

  • Useful for studying end-to-end user journeys and the user's POV, helped by screen-by-screen videos of people going through the app
  • Screenshots are well-organized into clear flows
  • Positioned in roundups as good for component-level pattern research — how different apps implement the same UI
  • Microinteraction videos called out as handy while prototyping, plus App Store screenshots for marketing inspiration

Common complaints

  • A reviewer reported the core video feature broken/unavailable, undercutting the main "watch real user journeys" pitch
  • Widely described as a much smaller, less comprehensive library than Mobbin
  • Maintenance doubts: the brand's X account appears dormant, reinforcing a "lightly updated" impression
  • Almost no independent discussion (no Reddit, HN, or G2/Capterra/Trustpilot), so little social proof

How people compare it

  • Consistently framed as a lighter-weight Mobbin alternative — niche on component patterns and real-app analysis, while Mobbin is seen as larger, more current, and more powerful
  • Often pitched as a cheap, low-commitment option (older listings cite ~$8.25/mo with a free tier), though live pricing is now higher; affordability was its main draw against pricier libraries
  • Free-tier nuance recurs: reviewers note individual listings were free while the curated/category view was paid
  • Compared against free options (UI.live, UXArchive, Banani) and broader platforms (Dribbble, Page Flows), where newer rivals add AI search and bigger asset libraries it lacks
