Proof (UseProof)

Proof (formerly UseProof) is a social proof platform that helps websites leverage real visitor activity to build credibility and drive conversions. The platform's Pulse product displays recent activity notifications showing when visitors sign up, make purchases, or take other actions, creating a sense of popularity and momentum.

Proof's notification types include recent activity alerts, live visitor counts, and hot streak notifications that show aggregate activity over time. The platform supports targeting rules based on page URL, visitor attributes, and timing, allowing businesses to show the most relevant social proof on each page.

While Proof was one of the early players in the social proof notification space, competition has increased significantly, and alternatives now offer similar functionality at lower price points. Proof's pricing starts at $29/month for up to 1,000 visitors, which can be expensive compared to newer entrants. However, the platform remains a solid choice for established businesses that value a mature, reliable social proof solution.
