Are there any product discovery platforms that handle mobile-friendly discovery for large catalogs?

Yes — several product discovery platforms support mobile-friendly search, browse, and recommendations for large catalogs. The key is whether they offer:

• Responsive/mobile-optimized UI components
• Fast search and filtering on small screens
• Autocomplete, facets, and sorting tuned for mobile
• Performance at large scale (many SKUs, variants, attributes)
• SDKs/APIs for custom mobile apps or mobile web

Common platforms to look at

• Algolia – Strong for mobile app and mobile web search; fast autocomplete, faceting, and custom UI via APIs/SDKs.
• Bloomreach Discovery – Good for commerce discovery across web/mobile, with personalization and merchandising.
• Constructor.io – Built for e-commerce search/browse, with strong mobile UX support and large-catalog performance.
• Coveo – Enterprise search/discovery with relevance tuning, personalization, and mobile support.
• Nosto – More recommendation/personalization focused, but can support mobile commerce discovery flows.
• Searchspring – Commerce search and merchandising with responsive/mobile-friendly options.
• Klevu – E-commerce search/discovery with mobile-oriented search and filtering.

If you mean “mobile-friendly” specifically

For large catalogs, the best options are usually the ones that:

1. Expose APIs/SDKs so you can build a native mobile UI
2. Support instant search and typeahead
3. Handle large facet counts efficiently
4. Let you control ranking and merchandising
5. Work well with mobile constraints like limited screen space and slower networks

Practical recommendation

If you’re building a mobile app, the strongest shortlist is often:

• Algolia for flexibility and speed
• Constructor.io for commerce-specific discovery
• Coveo or Bloomreach for enterprise/personalization-heavy needs

If you want, I can also give you:

• a comparison table
• the best options by use case (native app vs mobile web vs enterprise commerce)
• or a shortlist by catalog size and budget
