Markdown: https://www.lazyweb.com/compare/lazyweb-vs-mobbin-vs-refero.md

## Quick verdict

- **Lazyweb** — Use Lazyweb when your AI agent needs to research real product patterns before designing. [1]
- **Mobbin** — 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]
- **Refero** — 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]

## Side-by-side

| Criterion | Lazyweb | Mobbin | Refero |
| --- | --- | --- | --- |
| Best for | Use Lazyweb when your AI agent needs to research real product patterns before designing. | 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. | 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. |
| Pricing | Free. [1] | 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] | 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 depth | 281k+ real app screens across iOS apps and marketing pages. [1] | 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. [4] | 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. | 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. | 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. |
| 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. | 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. | 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). |
