Strapi

Strapi is the most widely used open-source headless CMS, with 72,000 GitHub stars and a plugin ecosystem that covers most common integration needs. You define your content types in a visual builder, Strapi generates the database tables and exposes the content through both REST and GraphQL APIs automatically, and your frontend framework consumes those APIs however it needs.

The practical advantage over WordPress or a traditional CMS is the clean separation between content management and presentation. Editors work in a familiar admin panel. Developers query a predictable API. The frontend can be anything: Next.js, a mobile app, a static site generator, or multiple consumers at once.

Self-hosting runs via Docker or a standard Node.js deployment. Strapi supports PostgreSQL, MySQL, SQLite, and MongoDB. For most production setups, PostgreSQL is the recommended choice.

The honest constraints are around the paid tier. Enterprise features including SSO, audit logs, content history, and review workflows sit behind a commercial licence. The Community Edition covers everything else, and for most small team or indie hacker projects the community tier is sufficient. Large organisations building internal tools or publishing platforms may hit the enterprise tier quickly.

With 72,000 stars and continued investment from the company behind it, Strapi’s longevity in the market looks solid — a meaningful factor for a tool you are building a content backend on.
