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.
Notion Sites
Notion Sites is a feature within Notion that lets users and teams publish their Notion pages as public websites, enabling everything from personal portfolios to company wikis to be hosted directly from Notion's workspace. The published sites maintain Notion's distinctive block-based layout and typography system. Notion-powered sites are identifiable through requests to Notion's CDN infrastructure, the presence of Notion-specific JavaScript globals, and the characteristic nested block structure in the HTML. Notion Sites is included with all Notion plans, which start free for personal use and scale to $10/user/month for team plans.
