Next.js
Next.js is the most used React framework for fast, SEO-friendly websites and web apps, developed by Vercel.
Next.js is a framework built on React, developed by Vercel since 2016. Today, when agencies build corporate websites or web apps with React, Next.js is the de facto standard, used by Netflix, Nike, and TikTok.
Typical projects: Corporate websites with CMS integration, online shops, SaaS products. Its main strength is server-side rendering. Pages load quickly and are easily readable by Google, which pure React without a framework cannot achieve. Image optimization and API routes for backend logic are also included in the project.
Nuxt offers the same concept for Vue, and for marketing pages without a development team, Webflow is the faster solution. The weakness: Next.js is tightly integrated with Vercel's hosting; while operating it on your own infrastructure works, it comes at the cost of convenience, a soft lock-in.
Ideal for companies with a development team or agency that want their web presence and web app in a single stack; many German agencies now build with it by default. Without developers, use Webflow or WordPress.
