What dbdiagram.io is
dbdiagram.io creates database relationship diagrams by letting users write DBML, its Database Markup Language. The cloud version supports SQL import and export, including Oracle imports using Oracle 19c syntax. Supported databases include PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, and BigQuery. Users can filter tables in the default diagram view; saving multiple customized views requires Personal Pro. That plan also includes an AI Assistant for schema design, modification, and optimization through natural language, with a monthly token quota. The editor extension supports VS Code, Cursor, Windsurf, and other Open VSX-based editors, with live ERD previews from DBML files. A CLI syncs local DBML files with diagrams and can publish documentation to dbdocs.io from a terminal or CI pipeline. Free diagrams can be shared with public links, while password protection and private mode require Personal Pro or Team. The Free plan costs nothing, Personal Pro is $20 a month, and Team is $60 a month. The Team trial lasts seven days, requires a payment method, and charges automatically when it expires.
