Lazyweb vs Mobbin vs Refero: Best Design Research Tool for AI Agents

A practical comparison of Lazyweb vs Mobbin vs Refero for product teams choosing a design reference or research workflow.

Quick Verdict

Lazyweb

lazyweb.com

Free, agent-first design research library with app trees, Design.md-style app files, and screen-version history.

Price
Free. [1]
Library
281k+ real app screens across iOS apps and marketing pages.
Agent access
Agent-first MCP setup across Codex, Claude Code, Cursor, Antigravity, hosted Claude connector paths, and other agentic platforms.

Mobbin

mobbin.com

A large, curated library of real shipped iOS, Android, and web app screens and step-by-step user flows for benchmarking UI patterns.

Price
Freemium — limited free tier; Pro from ~$10/mo and Team ~$12/seat/mo (both billed yearly, prices localized by region); Enterprise custom. 50% student discount. [4]
Library
Very deep: 621,500+ real shipped screens and 142,200+ user flows across 1,000+ apps (first-party, May 2026), with flows organized as complete journeys, not loose screenshots.
Agent access
Official MCP server (OAuth, Streamable HTTP, currently in beta) plus an official REST API. MCP needs any paid plan; REST API is Team/Enterprise only. Neither works on the free tier.

Refero

refero.design

A curated web-and-iOS design-reference library (150k+ real product screens, 6k+ flows) built for both designers and AI agents.

Price
Freemium — limited free tier; Pro reportedly ~$12-14/mo (~$8/mo annual, secondary sources conflict). Team per-seat (min 3 seats); a Lifetime plan and 40% student discount also exist. [25]
Library
Vendor-stated 150,000+ real product screens and 6,000+ user flows (Stripe, Linear, Notion, etc.) plus a "styles" layer; not independently audited, and older listings show much lower counts.
Agent access
Official first-party MCP (https://api.refero.design/mcp, Bearer/OAuth) with eight tools across Styles/Screens/Flows — but it requires a paid Pro plan and caps Pro at 8,000 tool calls/month.

Side-by-side Table

Criterion
Lazyweb
Mobbin
Refero
Best for
Use Lazyweb when your AI agent needs to research real product patterns before designing. [1]
Use Mobbin when you need a deep, curated catalog of real iOS/Android/web screens and full multi-step flows, and you (or your agent) have a paid plan for its MCP or API. [4]
Use Refero when an agent or designer needs curated web/iOS product references — especially SaaS dashboards, settings, and marketing pages — via a first-party MCP, and a paid subscription is acceptable. [25]
Pricing

Vendor-stated 150,000+ real product screens and 6,000+ user flows (Stripe, Linear, Notion, etc.) plus a "styles" layer; not independently audited, and older listings show much lower counts. [25]
Platform coverage
iOS apps and marketing pages today; web-app flows are not available yet. [1]
iOS, Android, and web apps, with version toggles per product and ~18 categories. "Web" means web-app UI; there is no dedicated marketing-website or email-design gallery. [4]
Web and iOS only (the MCP platform parameter accepts only "web" or "ios"). No Android, desktop, or email; strongest on web-first SaaS dashboards, settings, and marketing pages. [25]
MCP / API
Agent-first MCP setup across Codex, Claude Code, Cursor, Antigravity, hosted Claude connector paths, and other agentic platforms. [1]
Official MCP server (OAuth, Streamable HTTP, currently in beta) plus an official REST API. MCP needs any paid plan; REST API is Team/Enterprise only. Neither works on the free tier. [4]
Official first-party MCP (https://api.refero.design/mcp, Bearer/OAuth) with eight tools across Styles/Screens/Flows — but it requires a paid Pro plan and caps Pro at 8,000 tool calls/month. [25]
Agent readiness
Built for agents first, with skills that generate competitive analysis and large research reports. [1]
Genuinely agent-ready: the official MCP returns screen images, annotations, and metadata with natural-language search inside Claude Code, Cursor, Codex, and v0 — but only with a paid, authenticated account. [4]
Genuinely agent-ready: hosted MCP, eight scoped tools, structured per-screen metadata agents can read before fetching images, an MIT-licensed skill, and an OpenAPI spec. Gates are commercial, not technical (paid plan, call caps). [25]
