Chartdb
Create and edit database diagrams with ChartDB, which can visualize schemas from a database query.
About Chartdb
ChartDB is an open-source, web-based editor for creating and editing database diagrams. Users run a provided query in their database and paste the resulting JSON into ChartDB to display the schema as a diagram, which can be edited and annotated. It can generate DDL scripts in a different database dialect for migration, and works without an account and without providing a database password.
It supports PostgreSQL, MySQL, SQL Server, MariaDB, SQLite including Cloudflare D1, CockroachDB and ClickHouse. It is in public beta and can be used as a hosted version or deployed locally with npm or Docker; AI-based export requires an OpenAI API key or a custom inference endpoint.
