pgModeler

pgModeler - PostgreSQL Database Modeler - is an open-source data modeling tool designed for PostgreSQL. No more typing DDL commands. Let pgModeler do the work for you! This software unites the concepts of entity-relationship diagrams and the features that PostgreSQL implements as extensions of SQL standards. It also counts with a minimalist but functional database server administration module which allows the execution of any sort of SQL commands, database objects browsing, and data handling in a simple and intuitive UI.

pgModeler is open-source software, and you can get its source code anytime if you want to compile it by yourself. As a convenience, we provide compiled binary packages at a really fair price. Also, if you're interested in evaluating a binary package, you can get a demo copy before proceeding with the purchase. Since this is an independent project and without sponsorship, by buying any binary package you'll help keep the development active and at full speed!
