Versions:
Luna Modeler 13.0.0, published by Ideamerit, is a desktop data-modeling application designed for database architects who need to design, document, and maintain relational schemas for PostgreSQL, Oracle, SQL Server, MariaDB, MySQL, and SQLite. The program supports the complete modeling lifecycle, allowing users to start with a conceptual model, refine it into a logical structure, and then generate a physical model that respects engine-specific objects such as PostgreSQL composite types or Oracle sequences. Visual ER diagrams can be composed through an intuitive drag-and-drop canvas that offers multiple display modes, color themes, and layout options, while forward-engineering functions produce ready-to-run DDL scripts. For existing systems, reverse-engineering wizards connect through secure SSL/TLS channels to cloud instances such as Supabase or to on-premise servers, import SQLite files, and automatically reconstruct editable diagrams. Subsequent schema changes are tracked within the project file, and the software can emit ALTER statements for MariaDB, MySQL, and SQLite so that databases evolve without complete rebuilds. Interactive HTML documentation and PDF export communicate the design to stakeholders, and built-in schema-conversion utilities simplify migration between platforms. Released in ten major versions to date, the application has progressively expanded coverage from basic diagramming to advanced cloud connectivity and cross-engine synchronization. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g., winget), always delivering the latest version, and supporting batch installation of multiple applications.
