Personio migrated its website from a monolithic WordPress implementation to a composable stack of Vercel, Next.js, and Contentful. The company reported a more than 90% improvement in Core Web Vitals scores, a 29% improvement in mobile Largest Contentful Paint, and roughly 100% uptime. The headless architecture also improved developer experience and site security.
