About
Proof
Proof is a social proof platform that shows recent purchase notifications, live visitor counts, and customer testimonials on your storefront to reduce purchase hesitation at the moment of decision. The psychological mechanism is well-established: seeing that other real people are buying or viewing a product reduces the perceived risk of purchasing. The implementation is a lightweight script and the no-code setup takes minutes. Proof works best on product pages and checkout flows where doubt is highest, and is most effective for stores with genuine transaction volume to display (a store doing five orders a day should not show a live ticker). For brands with consistent daily sales looking for a low-effort conversion lift, it is one of the easiest tools to justify on ROI.
OptiMonk
OptiMonk is a conversion optimisation platform focused on on-site messaging: pop-ups, sticky bars, and embedded promotions that respond to visitor behaviour rather than firing indiscriminately. The targeting logic goes beyond basic exit intent to include cart value, traffic source, number of page views, and product viewed, which means the right message reaches the right visitor at the right moment rather than annoying everyone with the same generic offer. The template library is large and the setup is genuinely no-code. Where OptiMonk differentiates from simpler tools like Privy is in the personalisation depth and the A/B testing framework that lets you optimise message performance over time. Best suited to stores generating enough traffic to run meaningful tests.
