Ideamerit

Ideamerit s.r.o. is a software company based in the Czech Republic, part of the European Union, that builds desktop-native data modeling and schema design tools under the Datensen.com brand. The company describes itself as serving developers, database architects, DBAs and data engineers in more than 85 countries worldwide, and says its team has been working in database tooling and data modeling for over 20 years. Its products are sold and documented through the Datensen.com website, which functions as the commercial storefront and product hub for the Ideamerit tool suite. The flagship product is Luna Modeler, a professional data modeling and database design tool for relational databases including Oracle, SQL Server, PostgreSQL, MySQL, MariaDB and SQLite. Luna Modeler supports both model-first design — drawing entity-relationship diagrams from scratch and generating deployment-ready DDL and ALTER scripts — and reverse engineering of existing databases, so that a live schema and its model can be kept in step. The company positions Luna Modeler as enterprise-grade modeling at a fraction of the typical price, with small-team pricing, a free 14-day trial, and a one-time purchase model rather than a subscription. A distinguishing claim is that the tools work fully offline: schemas stay on the user's device and are never uploaded to the cloud. Alongside Luna Modeler, Ideamerit develops Moon Modeler for the NoSQL side, covering MongoDB and Mongoose ODM out of the box and also usable with Amazon DocumentDB, Azure Cosmos DB and similar document-oriented databases. Moon Modeler offers visual schema design, ER diagrams, validation script and Mongoose schema generation, reverse engineering of existing MongoDB databases, SSL/TLS connections to cloud solutions, and interactive HTML or PDF report export. A third product, Galaxy Modeler, is a schema design tool for GraphQL, with visual schema creation, multiple display modes, code generation, import from files or URL, and interactive HTML reports with PDF export. The company's stated philosophy is that professional database work deserves professional tools that respect their users: software that runs on the user's machine rather than in a vendor's cloud, stores schemas locally rather than on a third-party server, and is charged once rather than through an inescapable subscription. Ideamerit presents this as a deliberate contrast to SaaS-oriented tooling, and says support is handled directly by the development team. The products have evolved from earlier database design software into the current suite, with regular releases and long-term support for both Luna Modeler and Moon Modeler.

Ideamerit s.r.o. is a Czech software company that builds data modeling and database design tools under the Datensen.com brand. The company states that its team has been working in the field of database tooling and data modeling for over 20 years, and that its products evolved from earlier database design software into the current suite. It was founded on the observation that professional database work deserves professional tools that respect their users — running on the user's machine rather than in a vendor's cloud, storing schemas locally rather than on a third-party server, and charging once rather than locking users into a subscription. Over time the company assembled a portfolio of desktop-native modeling tools. Luna Modeler became the flagship: a data modeling and database design tool for relational databases including Oracle, SQL Server, PostgreSQL, MySQL, MariaDB and SQLite. It supports both designing a schema from scratch and reverse-engineering an existing database, and it generates deployment-ready DDL and ALTER scripts. Moon Modeler was developed for the NoSQL side, supporting MongoDB and Mongoose ODM out of the box and also usable with Amazon DocumentDB, Azure Cosmos DB and similar document-oriented databases. Galaxy Modeler extended the portfolio to GraphQL schema design. The products are distributed and documented through Datensen.com, which serves as the commercial storefront for the Ideamerit suite. The company reports users in more than 85 countries and says support is handled directly by the development team. Both Luna Modeler and Moon Modeler are described as actively developed and maintained, with regular releases and long-term support. Luna Modeler has continued to receive feature releases, including version 14.6 highlighted on the Datensen homepage, which introduced capabilities such as the Context Lens for instantly showing every object connected to a selected one, aimed at making complex diagrams readable. The company sells its tools with a free 14-day trial, no card required, and a one-time purchase model with no subscription and no lock-in.
