DBModeler review
A free web modeler with broad engine coverage and strong SQL workflow features.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
DBModeler is a browser-based ER diagram editor for designing relational schemas and organizing database projects. It is suited to developers and database professionals who need to model tables, fields, constraints, and relationships, import existing DDL, and produce SQL output without an account or card. The Free plan includes all features, supports 14 database engines, and has no usage quotas. Supported engines include PostgreSQL, MySQL, MariaDB, Oracle, SQL Server, SQLite, IBM Db2, Snowflake, BigQuery, Redshift, CockroachDB, YugabyteDB, TiDB, and DuckDB.
Its strongest area is the connection between visual design and SQL change management. Users can paste or upload existing SQL, generate engine-aware SQL and migrations, preview, export, or copy SQL, and add custom pre- and post-migration scripts. Version snapshots, diffs, rollback, migration SQL, and schema validator export provide a structured workflow for reviewing schema changes. This makes DBModeler a good fit for projects that need both reverse engineering and forward engineering rather than diagramming alone.
DBModeler also supports optional project synchronization through Google Drive, OneDrive, Dropbox, GitHub, and GitLab, with repository workflows available for GitHub and GitLab. The application is front-end only and stores projects locally by default, so teams seeking built-in collaboration should look elsewhere. Its web-only deployment is appropriate for browser-based work, while the absence of collaboration limits its fit for shared team editing. Choose DBModeler for free, engine-aware database modeling and versioned SQL workflows; choose an alternative when simultaneous collaboration is central.
