Leading open source headless CMS, fully JavaScript
If you need a CMS (content management system — the backend where you create and manage content for your website or app) and you want full control over it, Strapi gives you a customizable admin panel and API out of the box. Build your content types, define relationships, get a REST or GraphQL API automatically.
Open source fullstack Next.js framework with backend superpowers
If you need a CMS that lives inside your Next.js app instead of beside it, Payload embeds directly into your codebase. Define your content schema in TypeScript, get a full admin panel, REST and GraphQL APIs, auth, access control, and file uploads.
Flexible backend — turn your DB into a headless CMS or admin panel
If you have a database and need an instant admin panel, REST API, and GraphQL API without writing backend code — Directus wraps any SQL database and gives you all three. Point it at your Postgres, MySQL, or SQLite database and you get a polished admin UI, user management, file storage, and a full API layer.
Contentful is a platform — it bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
Including when one of these alternatives ships a major update. Free.
