Overview

d9 is an open-source, GPLv3-licensed fork of Directus 9, maintained independently by the French company La Webcapsule after Directus moved later versions to a more commercial licensing model.

It instantly generates REST and GraphQL APIs, a JavaScript SDK, a CLI, and a no-code admin app on top of any existing SQL database, without requiring a data migration.

Key Features

d9 supports PostgreSQL, MySQL, SQLite, OracleDB, CockroachDB, MariaDB, and MS-SQL, introspecting each database's schema to build an abstraction layer that keeps the underlying data unaltered.

It provides CRUD operations, configurable user permissions, complex querying, and webhook/flow-based automation, serving developers, analysts, and non-technical business users from the same underlying API.

Pricing

d9 is free and open source under the GPLv3 license, with no paid tiers or feature gates for the core software; it is self-hosted only.

La Webcapsule separately sells custom, contact-sales engineering-platform and ISO 27001-compliant hosting services that can incorporate d9 for organizations wanting a managed, compliance-oriented deployment.
