Model Query is a Java library that generates typed query definitions (QModel classes) from JPA entity projections via an annotation processor, enabling compile-safe, projection-first queries with filtering, paging, bulk writes, and vendor-specific SQL. It occupies a niche between Querydsl and Blaze-Persistence with a cleaner record-friendly API and rich documentation.

Target audience: backend Java developers using JPA/Hibernate and Spring Boot
