Vercel is expanding its analytics offerings to include Gatsby, providing developers with their Real Experience Score through data from actual visitors. The new feature allows for zero configuration and can be accessed by opening a Gatsby project in the Vercel dashboard. With this update, developers can track performance continuously and gain insights on Core Web Vitals from real user data across devices and regions. The expansion aims to enable consistently fast user experiences and support more frameworks, including Next.js, with analytics features for Res. By deploying with zero configuration, developers can scale their applications without breaking a sweat, and Vercel's global edge network ensures seamless performance.
