Design Databases Visually -
and Keep Them That Way
Luna Modeler turns database design into a picture your whole team can read: draw ER diagrams, generate deployment-ready SQL, document what you build, and keep the model in step with the real database — all on your own machine, no cloud required.

New in Version 14
Complex Diagrams, Instantly Readable
Once a model grows past a few dozen tables, finding what connects to what becomes guesswork. Context Lens ends that: select any table, view, or object and it opens a focused view of everything linked to it — relationships, dependencies, every line leading elsewhere — no more scrolling a 200-table diagram to answer "what does this touch?"

When you're designing a new system
Draw data models offline. No database required. Run forward engineering to turn your visual data model into deployment-ready DDL. Platform specific syntax, validated output.
When you inherit a database
Connect to a live database and reverse engineer it into a complete ER diagram automatically. Understand the database in minutes. New in v14: pick exactly which object types to bring in, so legacy databases don't drag in every trigger and procedure along the way.
When you need to change schema safely
Platform-Specific SQL for Every Database in Your Stack
Luna Modeler doesn't generate generic SQL that breaks at deployment. Every forward-engineered script matches your database's exact dialect.
- PostgreSQL — PostGIS types, Supabase, AWS RDS for PostgreSQL
- Oracle Database — on-premise, AWS RDS Oracle, Oracle Cloud
- SQL Server — Azure SQL Database, Entra ID auth
- MySQL and MariaDB — open-source stacks
- SQLite — embedded, file-based, and mobile application databases
Your Schemas Never Leave Your Machine
Luna Modeler is a desktop application. Your database credentials, ER diagrams, schema files, and generated SQL are stored on your own device only. No account required to use it. No schemas uploaded to our servers.
Your intellectual property stays in your hands.
The Luna Modeler sped up exponentially my modeling time and its highly detailed and well built model visualization helped the understanding throughout all knowledge levels users.

I have never found a data modeling system that is easy to use… Until I used your suite of tools Luna, Moon, Galaxy. Plus, all this at a fantastic price. Definitely recommend for anyone using data models in a full stack app.

Beats the rest of the pack for ease of use. Very fast to do basic tasks but has some really neat extensions.
