Sitecore headless means the front end is built separately from the content platform. Sitecore manages content, and the site is delivered through APIs to an application you build.
The Next.js SDK for Sitecore is the toolkit for this approach. It provides components and helpers for rendering Sitecore content in Next.js, including server-side rendering and static generation.
Teams gain freedom in front-end technology and can tune performance, while authors keep familiar editing tools.
See the results of this approach in our Regal Rexnord case study.
