Directus

Directus is an open-source data platform and headless CMS that turns any SQL database into an instant, fully-featured API and a beautiful no-code admin application. Rather than forcing your content and data into a proprietary structure, Directus layers on top of your existing (or new) database — Postgres, MySQL, SQLite and others — and mirrors your schema exactly, giving you a REST and GraphQL API plus a polished admin interface without writing backend boilerplate.

This database-first approach is what makes Directus special. Because it works with your real database rather than abstracting it away, your data stays portable and you're never locked in; developers retain full control over the schema, while non-technical team members get an intuitive app to manage content, records and assets. It's equally at home as a headless CMS powering websites and mobile apps, and as an internal data platform for managing business data, building admin panels or exposing data to other systems.

Directus is feature-rich for a tool you can self-host for free: granular roles and permissions, a flexible asset and file management system with on-the-fly image transformations, customizable dashboards and insights, automation flows for no-code logic, and extensibility through custom extensions and hooks. You can self-host it for full control and zero licensing cost, or use the managed cloud for convenience. For development teams that want the flexibility of a headless backend, the transparency of open source, and an admin experience their whole team can actually use, Directus offers a compelling, modern alternative to both traditional CMSes and closed backend-as-a-service platforms.
