Overview
SeaORM is a relational ORM for building Rust web services. It provides asynchronous queries, entities and relations, ActiveModel persistence, migrations, and raw SQL across MySQL, MariaDB, PostgreSQL, and SQLite.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Key features
Model one-to-one, one-to-many, many-to-many, and self-referencing relations
SeaORM models relations at the Entity level. The 2.0 dense entity format can keep relation declarations with the model, and the CLI can generate entities from an existing database.

Load and persist nested object graphs with higher-level APIs
Smart Entity Loader chooses joins or data-loader queries based on relation shape to avoid N+1 patterns. ActiveModel builders can persist nested object graphs while SeaORM resolves dependency order.

Best fit
Fits REST, GraphQL, and gRPC backends that want one database abstraction
It suits Rust services that want filtering, pagination, nested queries, migrations, and raw SQL in one ORM. The repository includes integrations with Axum, Actix, GraphQL, Tonic, and other frameworks.

Before adoption
Regression-test relation and schema-sync behavior across 2.0 patch updates
Version 2.0.4 fixes linked-join alias and condition handling as well as MySQL schema-sync behavior. Applications using complex relations or entity-first schema sync should verify generated SQL and migration outcomes when upgrading.

Supplemental curator note
SeaORM fits Rust backends that want a higher-level entity, relation, and migration layer on top of SQLx. Version 2.0 expands entity-first and nested-persistence workflows, so 1.x migrations should review generated entities and relation definitions carefully.

Clone the reviewed SeaORM release
Clone the reviewed SeaORM 2.0.4 tag. The quickstart requires Rust 1.85 or newer.
git clone --depth 1 --branch 2.0.4 https://github.com/SeaQL/sea-orm.git - 2
Enter the Quick Start project
Enter the official single-file quickstart. It uses an in-memory SQLite database, so no database server setup is required.
cd sea-orm/examples/quickstart - 3
Run the official Quick Start
Run the example covering entities, relations, schema sync, CRUD, and nested persistence.
