What is Next.js?

Next.js is a web framework built on top of React that handles rendering, routing, and performance optimizations out of the box. It lets developers build websites and apps that load quickly, rank well in search, and scale to millions of visitors without rewriting the foundation. Maintained by Vercel, it has become the default stack for most ambitious B2B websites built in the last three years.

Why it matters

Pick the wrong framework and you pay for it forever. Slow pages, bad SEO scores, engineers stuck wrestling with the tool instead of shipping features. Next.js solved most of those problems. Pages render server-side so Google sees the content immediately. Images, fonts, and scripts are optimized without anyone thinking about it. A new marketing page goes from Figma to production in days, not sprints. It is boring tech in the best sense — proven, maintained, hireable. When a CMO asks why their dev keeps mentioning Next, this is the answer: it is the shortest path from idea to a site that actually performs.

How it works

Engineers build each page as a React component, then Next.js decides how to deliver it — pre-built at deploy time, rendered on the server for each request, or refreshed on a schedule. The framework handles routing automatically based on the file structure, optimizes images and fonts on the fly, and splits the JavaScript so visitors only download what they need. When paired with a headless CMS like Sanity, marketers publish in the CMS and Next.js renders the new content within seconds. Deployment usually runs on Vercel, where the same team behind Next.js handles hosting, caching, and previews for every change.
