Best Free & Open Source Alternatives to Contentful

Strapi is an open-source headless CMS built on Node.js and TypeScript. Content models are defined in the admin panel with the Content-Type Builder — fields, reusable components, Dynamic Zones and a blocks-based rich text editor — and Strapi generates a REST API and a GraphQL API for every content type, ready to consume from any website, mobile app or IoT device.

Out of the box it includes role-based access control for both admin users and API consumers, API tokens, webhooks, a media library, internationalization with unlimited locales, draft and publish, and a plugin marketplace. Controllers, services, routes and middleware can all be overridden in code, TypeScript types are generated for your content, and the admin panel itself is a React application. Content lives in SQLite for local development or in PostgreSQL, MySQL or MariaDB in production.

Deployment is self-hosted on Node.js 20 through 26, via Docker or any Node-capable host, or managed through Strapi Cloud. Content can be moved between environments with the export, import and transfer CLI commands, and data can be migrated from another instance or another CMS during a rebuild.

The Community edition is MIT licensed and free with unlimited content types, entries, API calls and locales. Paid self-hosted plans add Growth features — Strapi AI, Live Preview, Releases and 14-day Content History — while the Enterprise tier adds SSO, Review Workflows, Audit Logs and a SOC 2 report. Compared with Contentful, Strapi follows the same API-first model but runs on your own infrastructure, with the database, uploads and admin panel under your control. Compared with WordPress, there is no rendering layer at all: Strapi only models and serves content, and you build the frontend yourself.

Payload is an open-source, TypeScript-first headless CMS and application framework. Since version 3 it runs natively inside Next.js: you define collections, fields, hooks, access control and authentication in code, and Payload generates the database schema, REST and GraphQL APIs, and a customizable admin panel. It supports PostgreSQL, MongoDB and SQLite, so it can be self-hosted anywhere a Next.js or Node app runs.

Because the content model lives in TypeScript, schemas are versioned in git and reviewed like the rest of the codebase — no click-ops configuration and no vendor lock-in. Payload includes drafts and versioning, localization, rich-text editing, visual editing, file storage adapters and granular access control, and it suits content sites, internal tools, multi-tenant SaaS backends and ecommerce. Recent releases add RAG and vector-embedding support to make content AI-ready.

Payload is MIT-licensed and free to self-host with no content or seat limits. Figma acquired the team in June 2025, and in October 2026 Payload became available inside Figma Make, where Figma can host the database, authentication, file storage and admin panel for generated sites. Payload Cloud is paused for new projects while existing projects keep running; enterprise support, SSO and advanced features are available commercially. Teams commonly adopt Payload as a 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.

Directus is a source-available headless CMS and backend that wraps an existing SQL database and instantly exposes it through REST, GraphQL and WebSocket APIs. Instead of enforcing its own content model, it introspects your tables and adds metadata, so you keep control of the schema while non-technical users manage data in the no-code Studio.

It covers granular policy-based access control, a visual automation builder (Flows), dashboards (Insights), content versioning with native drafts and publishing, collaborative editing, localization, a media library with on-the-fly transformations, and an extension system. Version 12 adds a redesigned Studio, draft and publishing workflows, and AI assistant/MCP tooling. Because the same backend serves content editors, developers and business users, Directus is used for headless CMS, backend-as-a-service, product information management and internal tools.

Directus is licensed under the Monospace Sustainable Core License (MSCL-1.0-GPL), a source-available license that permits modification and self-hosting but forbids competing hosted offerings; each release becomes GPL-3.0 after four years. A free Core tier is available to everyone with seat and collection limits, and organizations under $5M in annual revenue with fewer than 50 employees can use the full platform free through the Open Innovation Grant. Larger teams buy Teams or Enterprise licenses, or use Directus Cloud.

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.
