Vercel Analytics

Vercel Analytics is a real-user monitoring (RUM) platform integrated into the Vercel deployment ecosystem. It captures performance metrics from production users, including Core Web Vitals (Largest Contentful Paint, First Input Delay, Cumulative Layout Shift), page load times, and JavaScript execution metrics. Unlike synthetic monitoring (Lighthouse), RUM data reflects actual user experience across browsers, networks, and devices. Vercel Analytics helps teams identify performance bottlenecks that affect real users, quantify business impact (slower pages = lower conversion), and track improvements over time. It's tightly integrated with Next.js and Vercel's deployment pipeline, making it ideal for teams already using that stack.
