Which App to Choose
You want social proof popups that pull from real order data, paired with countdown timers, exit intent, and a free shipping bar — all in one app, with no PageSpeed penalty. Best for: stores using Klaviyo for email who want on-site conversion widgets handled separately, and merchants who want the full stack at the lowest price.
You want social proof popups bundled with email list-building and automated flows. Privy does both well — but you're paying for the email platform whether you use it or not. Best for: stores without a dedicated email provider who want popup-to-email-flow automation.
You're currently paying for 5+ separate apps (social proof, reviews, upsells, currency converter, etc.) and want to consolidate. Vitals replaces many of them at a flat monthly cost. Best for: growing stores that have accumulated too many apps and want to simplify billing and admin.
