Best Free & Open Source Alternatives to Contentful

What is Payload?

Payload is a fullstack, TypeScript-first headless CMS and application framework that runs on top of Next.js, Express, and React. It gives developers a fully type-safe backend, an auto-generated admin UI, and a database layer (supporting PostgreSQL and MongoDB) out of the box, with no glue code required.

Unlike most CMSes that sit on the side of an application, Payload is designed to be the application: collections, fields, hooks, access control, authentication, and a customizable admin panel are all defined in code. You can ship Payload as a stand-alone headless CMS, mount it inside an existing Next.js app, or use it as a framework for building complete products — internal tools, multi-tenant SaaS backends, content platforms, and more.

Why teams use Payload instead of a paid CMS

• Truly open source under the MIT license — the entire codebase, including the admin UI, is on GitHub.
• Code-first configuration — content models are TypeScript, not click-ops forms, so they live in git and review with the rest of your code.
• Self-hostable anywhere Node runs, with first-class support for PostgreSQL and MongoDB.
• No vendor lock-in — your data, schema, and code are all yours. No content limits, no per-seat pricing, no surprise migration project.
• Modern stack — Next.js, React, TypeScript, GraphQL and REST APIs, draft/publish workflows, localization, access control, and rich blocks/fields.

Payload also ships a hosted cloud option (Payload Cloud) for teams that want managed infrastructure, but the open-source edition is fully featured and free forever. It is a popular self-hosted replacement for Contentful, Sanity, Prismic, Storyblok, and Builder.io.

TinaCMS is a fully open-source headless content management system designed for modern web development workflows. It offers powerful Markdown and MDX support with an intuitive visual editing interface that makes content editing accessible to non-technical team members.

With its Git-based architecture, TinaCMS provides version control for all content changes and supports both statically generated and server-side rendered pages. The GraphQL API allows flexible content queries, while the live preview feature enables real-time visual editing of content.

TinaCMS is particularly well-suited for Next.js and React applications, offering seamless integration with modern frontend frameworks. It supports references between documents, custom content modeling, and can be self-hosted or used with TinaCloud for managed hosting.

Strapi is an open-source headless CMS written entirely in JavaScript and TypeScript that gives development teams full control over content modeling, APIs, and deployment. Content types are defined via a visual builder that combines fields, reusable components, and Dynamic Zones, then automatically exposed through both REST and GraphQL endpoints. The admin panel offers content editors a clean interface for managing and localizing content across multiple languages.

The platform includes role-based access control for both admin users and API consumers, a built-in media library, a plugin system for extending behaviour, and support for PostgreSQL, MySQL, MariaDB, and SQLite. Strapi runs self-hosted on any Node.js-compatible environment, or as a managed deployment through Strapi Cloud.

Strapi is designed for teams building websites, mobile apps, IoT products, or any project that needs a framework-agnostic content API — ranging from small prototypes to enterprise deployments requiring SSO, audit logs, and custom workflows.

Directus is a headless CMS and backend-as-a-service platform that wraps any SQL database and instantly exposes it through REST and GraphQL APIs. Rather than enforcing a rigid content model, Directus connects to an existing database and provides a visual admin interface for managing data, without altering the underlying schema. Teams can model content freely while developers consume it through standardised APIs.

Key features include granular, policy-based access control, a visual workflow automation builder, support for multiple databases (PostgreSQL, MySQL, SQLite, and others), a media library with asset transformation, and built-in internationalisation. The same interface serves developers, content editors, and business users, making it practical for diverse team structures.

Directus is used for headless content management, backend-as-a-service for web and mobile apps, product information management, and any project that needs a flexible data platform without committing to a specific frontend or application framework.

CometCMS is a lightweight, open-source headless content management system designed for simplicity and ease of self-hosting. It pairs a PHP backend with a Vue.js-based admin interface, making it straightforward to manage content while delivering it via API to any frontend.

The project emphasizes a minimal setup experience and a clean UI for content editors, offering a practical alternative to complex proprietary headless CMS platforms.

WollyCMS is a self-hosted headless CMS designed from the ground up for Astro.js projects. It combines the sophisticated content architecture of traditional CMS platforms with modern web development workflows.

Built on Hono 4.x with a TypeScript backend and SvelteKit 5 admin interface, WollyCMS supports SQLite, PostgreSQL, and Cloudflare D1 as database backends, with storage options including local filesystem, S3, and Cloudflare R2. It features a visual drag-and-drop page builder, full revision history with diffs and rollback, scheduled publishing, and configurable workflows.

WollyCMS exposes both REST and GraphQL APIs with full-text search, built-in WCAG AA accessibility audits, automatic image optimization via Sharp/WebP, and real-time multi-user presence tracking — making it a compelling alternative to heavyweight SaaS CMS platforms for Astro-based sites.
