SQLAlchemy leads on 1 check, Doma on 0, and 3 are even. Who comes out ahead on the 4 yes/no, price and count checks where we have data for both products. The editor score weighs everything else too.

Our verdict

  • Highest scoreSQLAlchemy · 9.1/10
  • Free planboth
  • Most featuresSQLAlchemy · 3 of 3

SQLAlchemy scores higher on our rubric for database query builders: 9.1 against 7.9 out of 10; our editors rank them #2 and #7.

On type safety, Doma gives you Static where SQLAlchemy offers Optional. SQLAlchemy offers async queries; Doma doesn't.

SQLAlchemy is the better fit for python teams needing SQL construction plus ORM tools. Doma is the better fit for java or Kotlin teams wanting generated, type-safe queries.

Our review
Pros
  • Build queries with function- and expression-based SQL construction.
  • Map Python classes to tables with ORM querying and persistence.
  • Use six built-in dialects, with synchronous and asynchronous drivers.
  • Compile-time checks and generated metamodels catch query issues during compilation.
  • Criteria and SQL builder APIs cover search, insert, update, and delete.
  • Eight SQL dialects plus Spring Boot and Quarkus integrations.
Cons
  • Designed for Python rather than multiple programming languages.
  • Self-hosted deployment means teams manage their own runtime environment.
  • External dialects require projects beyond the six built-in dialects.
  • Self-hosted library, not a managed database service.
  • Asynchronous queries are not supported.
  • Kotlin projects use the separate doma-kotlin library.
