What You Get with Luna Modeler
Data Modeling Tool for PostgreSQL
A Better Way to Design PostgreSQL Databases
Stop sketching schemas on whiteboards. Luna Modeler gives you a visual environment to model, modify and document your PostgreSQL databases. It is fast, intuitive, and built for the 2026 dev workflow.
Visual Modeling That Actually Works
It isn’t just about drawing boxes. The tool understands PostgreSQL specifics. It handles your Enums, Domains, and Composite types without breaking a sweat.
You can create new objects with predefined settings, assign schema to database objects, divide diagrams to sub-diagrams etc.
Reverse Engineering – Turn Legacy Postgres Schemas into Clear Visual Maps
Connect Luna Modeler to your PostgreSQL database and watch it build a detailed data model with an ER diagram automatically. It’s the fastest way to document a project you’ve just inherited or to spot bottlenecks in a messy schema.
SSH/SSL/TLS connections are supported in the Professional Edition.
Generate Deploy-Ready SQL Scripts for PostgreSQL
No more manual coding for every schema change. Preview your DDL/SQL code instantly or use custom templates to generate exactly what your workflow requires. It handles the syntax for Postgres so you don’t have to.
Share Documentation That People Actually Read
Luna Modeler turns your diagrams into interactive HTML reports or high-res PDFs. If your database is huge, break it into smaller sub-diagrams. This makes it easy for your team to understand specific modules without getting lost in a massive “spaghetti” map.

Frequently Asked Questions on Database Design for PostgreSQL
Use a data modeling tool that knows Postgres. Luna Modeler lets you define tables, enums, domains, composites, sequences – all the PostgreSQL-specific objects. It tracks dependencies between objects and generates SQL scripts. It’s not a drawing app. It understands your database.
Yes. Connect to any Postgres instance – local, Supabase, AWS or self-hosted. Luna Modeler reads the schema and builds an ER diagram automatically. Good for documentation, onboarding new team members, or understanding a database before making changes.
You can export your entire diagram as PostgreSQL specific SQL script with a single click. Luna Modeler allows you to include pre/post SQL blocks and write templates for custom scripts as well.
In Luna Modeler you can create a conceptual, logical or physical data model. The logical data model can be converted to a physical model for PostgreSQL, SQL Server or other platforms. For more accurate database modeling, start with the physical model for the selected database system.
Yes, it’s available for Windows, macOS, and Linux. Supported database platforms include: PostgreSQL, Oracle Database, SQL Server, MySQL, MariaDB and SQLite.
