Platform Overviews
Next.js
Next.js is the world's most popular React framework for production web applications, created and maintained by Vercel — powering the frontends of companies like Vercel, TikTok, Twitch, and Hulu. It supports multiple rendering strategies: static site generation (SSG), server-side rendering (SSR), incremental static regeneration (ISR), and client-side rendering — often mixing strategies across different pages within a single application. Next.js is the default choice for new React projects requiring SEO, performance, and full-stack capabilities through its API Routes and Server Components. Next.js apps are identifiable through /_next/static/ paths for all compiled JavaScript and CSS chunks, the __NEXT_DATA__ JSON embedded in every page's HTML containing initial props, x-powered-by: Next.js HTTP headers on most deployments, and the Next.js chunk naming convention for split JavaScript files.
Contentful
Contentful is the world's leading headless Content Management System, used by enterprise teams at Nike, Spotify, and Burger King to manage content across websites, apps, and digital experiences from a single platform. Unlike traditional CMS platforms, Contentful separates content storage from presentation entirely — it provides a REST API and GraphQL API that any frontend framework can query, then renders content through whatever technology the team chooses. This architecture means Contentful often powers Next.js, Gatsby, or Nuxt frontends rather than having its own rendering layer. Sites backed by Contentful are identifiable through their media CDN domains: images.ctfassets.net and downloads.ctfassets.net serve all stored assets, and these URLs appear in image src attributes and link hrefs throughout the page. Contentful plans start at a free Community tier, with Team plans from $300/month for professional workflows.
