ChartDB is an open-source, web-based database diagram editor that visualizes database schemas as ER diagrams from a single 'smart query', with interactive editing and SQL DDL export in multiple dialects. It supports PostgreSQL, MySQL, SQLite, MariaDB, and SQL Server, and can be used in the cloud or self-hosted via Docker or npm.
Use cases
- visualize my database schema as an ER diagram
- design database diagrams without connecting to the database
- generate DDL scripts to migrate from MySQL to PostgreSQL
- document database schema for team discussions
- draw ER diagrams from a text prompt using AI
- keep database diagrams in sync with schema changes
- embed interactive database diagrams in documentation
When to choose
- you need fast, no-credential schema visualization via a single query
- you want an open-source, self-hosted diagramming tool with no table limits
- you need cross-dialect SQL export for schema migrations
- you want AI-assisted ER diagram generation and schema suggestions
When to avoid
- you need built-in user management and versioning in a self-hosted setup (cloud-only features)
- you require full database administration or query execution, not just diagramming
- you need offline desktop tooling rather than a web app
