pgModeler is an open-source, cross-platform visual database modeling tool built specifically for PostgreSQL, letting users design entity-relationship diagrams and generate DDL/SQL scripts without hand-writing them. It is written in C++ with Qt and offers a free Community Edition plus a commercial Plus edition with reverse engineering, diff/sync, and database management features.
Use cases
- design a postgresql database schema visually with an ER diagram
- generate DDL SQL scripts from a database model instead of typing them
- model tables, views, relationships, triggers and functions for postgres
- validate a database model for inconsistencies before deployment
- teach database modeling with an open-source ERD tool
- maintain complex postgres schemas with version-controlled model files
When to choose
- you work primarily with PostgreSQL and want deep support for its specific features
- you prefer visual drag-and-drop schema design over writing DDL by hand
- you want a free, open-source, cross-platform modeling tool with no cloud dependency
- you need Git-friendly schema model files stored locally
When to avoid
- you need reverse engineering or database diff/sync, which require the paid Plus edition
- you model databases other than PostgreSQL (e.g., MySQL, SQL Server)
- you only need a lightweight SQL client or query browser rather than a modeler
