TLDR
dbdiagram.io is a free database design tool that renders entity-relationship diagrams (ERDs) as users write DBML, its open-source database markup language, or import existing SQL schemas. It targets developers and data analysts with collaborative editing, diagram views for large schemas, AI-assisted design, SQL generation, sharing, embedding, exports, and version history. The site reports that more than 3 million diagrams have been created worldwide.
Key Takeaways
- Diagram as code: Write DBML and see ER diagrams appear live, allowing schema documentation and visualization without a manual drawing workflow.
- Schema interoperability: Users can import from databases or SQL dump files, generate SQL table-creation statements, and use a no-sign-up ERD Generator for DBML or SQL.
- Team-oriented design: Real-time collaboration works similarly to Google Docs; one-click links, embeds for Notion/Confluence and other documentation sites, and PDF/image export support distribution.
- Large-schema tooling: Collapsible table groups, tailored diagram views, and color coding help teams create focused views of complex database models.
- AI and history features: An AI assistant can generate database designs from plain-language requirements, while version history enables comparisons, restores, and copies from earlier diagram states.
- Free core product: dbdiagram.io says its app is free forever, with paid plans offering additional capabilities and unlimited diagrams.
