Galaxy Modeler - 2026 Pricing, Features, Reviews & Alternatives

Galaxy Modeler is a schema design tool for visual GraphQL data modeling. The software allows users to draw schema for GraphQL and generate schema definition scripts. Users can also make diagrams by importing existing GraphQL schemas. Galaxy Modeler is a desktop software that runs on macOS, Windows and Linux.

Users can visually design GraphQL schemas, specifying types, interfaces, enums, and drawing references among types, all while defining the specific details of GraphQL types and fields. The software's automatic addition of referenced fields to target types and immediate saving of changes, with an undo option, make the schema design process streamlined. Galaxy Modeler also helps import existing GraphQL schemas from files or URLs, enabling users to visualize specific GraphQL elements and add notes or other logical information to diagrams.

Once the schema design is complete, users can generate and preview GraphQL schema definition scripts, which can be customized using templates to create scripts, CSV files, or even UI components. The ability to export diagrams to PDF format and create HTML reports further enhances the documentation capabilities of the tool. Galaxy Modeler caters to a wide range of users, including software developers, data modelers, and educators, who require a tool for designing and documenting their GraphQL schemas.
