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.
drawDB
drawDB is a browser-based database diagram editor for modeling schemas, importing existing definitions and exporting SQL. It supports Generic, MySQL, PostgreSQL, SQLite, MariaDB, Microsoft SQL Server and Oracle diagrams. Imports include drawDB JSON and DDB files, DBML, and SQL scripts for the listed database systems; exports include SQL, image and document formats, drawDB JSON, DBML, Mermaid and Markdown. The free plan is listed at free and includes local diagrams, SQL dialects, and import and export. In the open-source editor, diagrams and custom templates live in browser IndexedDB, tying them to that browser profile. The maker says it can also be self-hosted with Docker. Pro options add cloud storage and sync, public sharing, AI assistance and version history; team options include workspaces, roles, diagram permissions and live collaboration. The AI assistant can create or edit schema elements from prompts, while the MCP server provides read-only access for compatible coding tools to schemas in Pro cloud workspaces. Schema context is sent to the AI service when it operates on a diagram.
