Platform Overviews
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.
Framer
Framer is an AI-powered design and publishing platform that lets designers create highly interactive, production-ready websites without writing code. Built on React under the hood, Framer generates real component-based code that performs at a framework level — enabling smooth animations, scroll effects, and responsive layouts that look professionally designed. It's the go-to tool for SaaS marketing sites, designer portfolios, and startup landing pages, and is trusted by companies like Pitch, Linear, and Loom. Framer serves all site assets from its proprietary CDN (framerusercontent.com) and injects distinctive data-framer-* HTML attributes throughout the DOM, making it one of the most reliably detectable AI builders. Sites are hosted on Framer's global infrastructure with custom domain support, and pricing starts at $0 for a Framer subdomain with paid plans from $10/month.
