Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Model Xtractor is a free Windows desktop application for inspecting relational database structures and creating entity-relationship models. It reverse-engineers tables, views, columns, and relationships from platforms including SQLite, Firebird, Microsoft SQL Server CE, Microsoft Access, MySQL, MariaDB, PostgreSQL, Microsoft SQL Server, Oracle, IBM Db2, SAP ASE, SAP SQL Anywhere, Snowflake, Amazon Redshift, Microsoft Azure, and Amazon Aurora. It is suited to database professionals and teams that need to understand existing relational systems through diagrams rather than build new schemas from a modeling environment.

Its main strength is the depth of its inspection and visualization options. Model Xtractor can present traditional or enhanced entity-relationship models, with rich or simplified diagram styles and expandable relationship items. Layouts can be customized with table and column aliases, client-side custom joins, and custom relationship chains. Diagrams can then be exported as images or PDFs, which fits documentation and review workflows. The vendor also states that its applications do not modify remote database data or metadata, an important fit for inspection-focused work.

The product’s narrow focus shapes the buying decision. It is free, and the published positioning centers on reverse engineering rather than forward engineering, SQL export, collaboration, or version history. It is also a Windows-only desktop application, so it suits individual inspection and documentation work more than cross-platform or shared modeling workflows. Choose Model Xtractor when the priority is free database discovery across many supported systems and flexible ER diagrams. Choose an alternative when you need schema generation, SQL output, collaborative editing, or a history of model changes.
