Mobile UI screenshot library · Alternative
Mobbin alternative
Mobbin is the largest curated library of mobile app UI screenshots — over 250,000 screens across 5,000+ apps. Designers use it to scan flow patterns (sign-up, onboarding, checkout) and component libraries for iOS and Android. It is screenshot-first: structured for visual reference, not design token extraction.
How AI2 Design differs
- AI2 Design ships a paste-ready 24-field brief bundle (18-field agent brief + 6-field curator) per item — palette, typography, spacing, motion, component recipes — that an AI agent (Claude, Cursor, v0) absorbs in one paste. Mobbin shows screenshots.
- AI2 catalogues marketing and product pages (not mobile apps) with observable design tokens — every hex and px in the brief is grounded in the captured DOM, not extracted from a screenshot.
- AI2 includes a public design extractor — give it any URL and you get the same token bundle, immediately downloadable as Markdown, JSON, CSS, or Tailwind.
- AI2 is free during the early-access window; Mobbin is subscription-only ($30+/month).
