Strapi is a headless content management system. Developers define content models, and Strapi generates a complete API that a website, mobile app or other client can consume, while editors get a friendly admin interface for writing and managing content. It is written entirely in JavaScript and TypeScript on Node.js.

A visual Content-Type Builder lets you design structures without code, and every content type gets REST and GraphQL endpoints automatically. Granular roles and permissions, a media library, internationalization and draft and publish workflows are built in. It works with SQLite, PostgreSQL, MySQL and MariaDB, and offers a plugin system and a customizable admin dashboard. Requests pass through routes, middlewares, controllers and services, which is where backend customization happens. Strapi AI adds help with content modeling, media alt text and translations.

You can self-host Strapi on your own infrastructure or use Strapi Cloud, the managed service. Its license is listed as 'Other' in the repository metadata, so confirm the terms for any enterprise features. It suits teams building Jamstack or multi-channel sites that want a flexible, developer-first backend.

Payload is an open-source CMS and application framework built on Next.js. Rather than running as a separate service, it can be installed directly into an existing Next.js app folder, giving you a TypeScript backend and an admin panel in the same codebase. You can use it as a headless CMS or as the foundation for a full application.

Because the backend lives alongside the front end, you can query your database straight from React Server Components and deploy anywhere, including serverless platforms such as Vercel. Both the admin interface and backend logic are described as fully extensible, with GraphQL and REST access, support for MongoDB and PostgreSQL, and no dependence on another SaaS vendor. A website template demonstrates rich text blocks, on-demand revalidation and live preview.

Payload is MIT licensed and written in TypeScript. It suits development teams that already build with Next.js and React and want content management they fully control, as an alternative to hosted headless CMS products or to maintaining a traditional PHP-based system.

Directus is a collaborative backend and headless CMS that sits on top of an existing SQL database. You connect a database, and it generates production-ready REST and GraphQL APIs, leaving your schema exactly as built, along with a no-code interface where non-developers can manage content and data.

Beyond content management it provides authentication and access control, so the same install can power websites, apps, admin panels and internal tools. A native Model Context Protocol server gives AI assistants such as Claude, ChatGPT and Cursor secure access to business data. Supported databases include SQLite, MySQL, PostgreSQL and SQL Server, and the app is built with TypeScript and Vue. A template CLI, run through npx, can initialize a project quickly.

Directus can be self-hosted on servers you control, or run on the vendor's Directus Cloud. The repository license is listed as 'Other', so review the terms to see which uses are free. It suits teams that want an API and admin layer over data they already have, without writing a custom backend.

Decap CMS, previously known as Netlify CMS until early 2023, is an open-source content editor designed for sites built with static site generators. It gives non-developers a simple interface for adding and editing content, while the content itself is stored as files in a Git repository.

It works as a single-page React app that you include under the /admin path of your site. A YAML configuration file describes your content model, and you can adjust the CMS layout to match the site. When someone visits /admin they log in and can then create or edit entries, with changes committed to Git. There are two ways to set it up: a quick install with a single HTML file plus a config file that loads scripts from a CDN, or a fuller installation integrated into your static site build for more flexibility.

Decap CMS is licensed under MIT and is a client-side app, so there is no database server to run. It is a popular choice for Jamstack sites on generators like Hugo, Jekyll and Eleventy, where teams want editors to manage content without touching code.

TinaCMS is an open-source headless content management system built around files in Git. Content in Markdown, MDX, JSON, YAML and other formats lives in your own GitHub repository, and editors work on it through an admin interface instead of editing raw files.

Content is exposed through a GraphQL API that supports queries on fields such as an author's first name, references between documents, and both statically generated and server-side rendered pages. An optional, opt-in live preview lets less technical editors see changes to Markdown content as they edit. It is commonly paired with Next.js and React sites.

Tina is written in TypeScript and licensed under Apache-2.0. You can test a starter site locally or try a demo on TinaCloud, the hosted service from the same team. Documentation, a public roadmap, GitHub Discussions and a community Discord are available for support.

Keystone is a headless CMS and application framework for Node.js. You describe your schema in code, and it produces a GraphQL API and a management UI for your content and data, without boilerplate or bootstrapping, while still letting you extend the back end like a custom one.

Keystone 6 is published on npm under the @keystone-6 namespace, and its packages target the Node maintenance and active LTS versions. The documentation includes a Why Keystone page, a getting-started guide using the create-keystone-app CLI, examples, an API reference and practical guides. Keystone 5 is in maintenance mode and lives in a separate repository.

The project is written in TypeScript and licensed under MIT. You host it yourself on a Node.js server with a database of your choice, and it is used by developers who want a code-first CMS with a typed GraphQL API for websites, apps and internal tools.

Builder is the visual development platform from Builder.io, and this repository holds its SDKs, usage examples, starter projects and plugins. The platform connects to an existing site or app so teams can edit visually and generate code using their own components, starting from Figma designs or a drag-and-drop editor.

Updates can be published through the SDKs or exported as code. The SDKs cover frameworks such as React, Vue, Svelte, Angular, Qwik and React Native, and the topics also mention headless CMS use, landing pages, Shopify and Next.js. A free account can be created to try it out, and a community forum handles questions.

The code in this repository is MIT licensed and written in TypeScript, but the editing platform itself is a hosted commercial service rather than software you host. It suits front-end teams that want non-developers to build and update pages from a shared component library.

Webiny is a content platform designed to be hosted in your own AWS account on serverless services. It is built as a TypeScript framework that developers extend with code, rather than a closed product configured only through a UI, and it runs on Lambda, DynamoDB, S3 and CloudFront with infrastructure provisioned by Pulumi in a single deploy command.

The platform includes a headless CMS with custom content models, a GraphQL API, field-level permissions, localization and versioning, plus a visual website builder with a Next.js SDK, a file manager for digital assets with CDN delivery, multi-step publishing workflows with approvals and scheduling, and native multi-tenancy that isolates data, users, assets and permissions from one deployment. The Webiny Framework adds lifecycle hooks, dependency injection and GraphQL schema extension, and an MCP server supports AI-assisted development.

It is aimed at developers at larger organizations, including SaaS companies that white-label it inside their products. The repository lists the licence as Other, so check the licence file for terms. It is self-hosted on AWS, so teams need AWS expertise and accept AWS costs for the underlying services.

Sanity is a headless content management platform for teams that treat content as structured data. Its open-source Sanity Studio is a React application that developers configure in code to build editing workspaces, while content is stored in Sanity's hosted backend and delivered to websites, mobile apps and other applications through APIs.

The vendor's site describes a wider product line: Content Lake as the data store, Live CDN for delivery, Content Releases, a Media Library, Functions, an App SDK, an MCP server and a Content Agent for AI-assisted content operations. Real-time editing is a long-standing trait of the Studio, according to the repository topics. Solutions are pitched at e-commerce, media and publishing, and SaaS teams.

The Studio code is MIT-licensed and can be deployed on any host you choose, but the content backend is operated by Sanity as a managed service, so a fully self-hosted setup is not available. A pricing page on the vendor's site lists the plans.

ApostropheCMS is a full-stack content management system and framework built on Node.js and MongoDB. Editors change content right on the live page and see results immediately, rather than switching between a separate admin interface and a preview. Developers can work in current JavaScript, or run it as a headless back end behind any front-end framework.

The project describes its key features as in-context editing and headless readiness, so teams can pick between a traditional website approach and a decoupled one. It is positioned for developers and content teams who want a unified JavaScript environment from the database to the browser. Documentation, a demo and a roadmap are linked from the repository, and topics include the Jamstack and website builder keywords.

The repository metadata does not state a license, so check the project terms before adopting it. ApostropheCMS runs on your own Node.js hosting with a MongoDB database. It suits organizations wanting an editor-friendly CMS written in JavaScript.
