pgModeler

The tool provides a visual environment for designing PostgreSQL schemas without writing DDL manually. Users can create, edit, and organize tables, columns, indexes, constraints, and other database objects through an interactive interface. A built‑in code generation engine translates the visual model into PostgreSQL‑compatible SQL scripts, handling the database’s specific features automatically.

It is aimed at developers, database architects, and administrators who need to plan or modify PostgreSQL databases and prefer a graphical workflow. The application runs on Linux, Windows, and macOS, and the source code is available under an open‑source license, allowing community contributions and custom builds.

Recent stable releases include version 1.2.3, which adds UI refinements, bug fixes in model loading, validation, and connection handling. An early‑access 2.0 alpha introduces a modernized user interface and updated editing forms, reflecting ongoing effort to improve usability while maintaining full compatibility with PostgreSQL.
