Directus

Directus is an open-source headless CMS and data platform that wraps any SQL database — new or existing — with an instant REST and GraphQL API and a no-code admin app. Rather than imposing its own database schema, Directus mirrors your actual database tables and columns, so developers keep full control of a standard SQL database while content editors and business users get a friendly interface to manage the data. This "database-first" design makes it equally useful as a headless CMS for websites and apps, an internal data hub, or a backend for products — one of the reasons it is widely adopted by developer teams.

The platform pairs developer power with no-code accessibility. It auto-generates APIs and a customizable admin app over your data; supports granular roles and permissions, workflows, and flows (automations); and handles files/assets, so it can run content for any front end (web, mobile, IoT). Directus adds extensibility (custom extensions, hooks, and a modular architecture), dashboards and insights, and AI features — while remaining open source and self-hostable. Its source-available BSL license is free for smaller organizations and self-hosting, with commercial cloud tiers for teams that want managed hosting and enterprise features.

Directus serves developers and teams that want an API and admin layer over their own SQL database — as a headless CMS or data platform. It is free and open source to self-host (and free for organizations under about $5M revenue / 50 employees). Directus Cloud offers a Professional plan from around $99/month (studio users, database entries, and API requests) and a Team plan around $499/month (billed annually; more collections and included SSO), with custom Enterprise. It competes with Strapi, Contentful, Sanity, and Payload, differentiating on wrapping any SQL database with an instant API.
