Fomo pioneered social proof notifications. ProofNudge takes the concept further with 60+ real-time variables, conditional logic, product rankings, and zero fake data.

Fomo is a solid product that helped define the social proof category. Here is why some merchants look for an alternative.
Fomo offers roughly 10 template variables. ProofNudge provides 60+, covering views, carts, sales, stock levels, compare-at pricing, collection stats, and product rankings. More data means more relevant messages.
Fomo allows simulated social proof (e.g., "Someone in New York just purchased...") without real order data. ProofNudge only displays verified, real-time data from your store. Shoppers trust authentic signals.
Fomo is limited to corner toast popups. ProofNudge lets you place messages as inline theme blocks, on product images, or at any CSS selector. Put the right message exactly where it converts best.
Show a low stock alert only when inventory drops below 10. Display a trending product badge only for products with 50+ views today. ProofNudge's conditional display rules ensure messages are always contextually relevant.
Every number in a ProofNudge message comes from your actual store activity. Real-time visitor counts, cart additions, purchase notifications, stock levels — all sourced from real Shopify data in real time. There is no option to fake or simulate notifications, because authenticity converts better than fabrication.
ProofNudge templates go beyond simple text replacement. With conditional logic, you can build rules like "If stock is under 5 and viewers are above 3, show urgency message." This means shoppers only see messages that are genuinely relevant to the product they are viewing.
ProofNudge can rank products within their type or collection — like "#2 most viewed in Running Shoes" or "Top seller in Summer Collection." These ranking variables provide social proof that is scoped and meaningful, not generic.
Install ProofNudge on your Shopify store and start showing real, data-driven messages that convert.
