In their own words
dbdiagram.io
dbdiagram.io creates database relationship diagrams by letting users describe schemas in DBML, its Database Markup Language. Developers and data analysts can design diagrams in the web app, while its cloud version imports and exports SQL. Supported databases include PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, and BigQuery; Oracle import uses Oracle 19c syntax. Free users can filter tables in the default view, while saving multiple customized views requires Personal Pro. Personal Pro 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 allow public link sharing; password protection and private mode require Personal Pro or Team. Free costs nothing; Personal Pro is $20 a month and Team is $60 a month. A 7-day Team trial requires a payment method and automatically charges when it ends.
