What each one is

The product in its own terms, so the numbers below have context.

Sequelize

Sequelize is an ORM that bridges JavaScript and TypeScript applications with multiple relational databases including PostgreSQL, MySQL, MariaDB, SQLite, Oracle, SQL Server, Snowflake, and DB2. It provides declarative schema modeling, relationship definitions, transaction support, and flexible data loading strategies.

Independently observed

SQLAlchemy

SQLAlchemy provides Python developers with a toolkit for working with SQL databases, featuring both a low-level SQL expression language and an optional object mapper. It balances flexibility and abstraction, allowing developers to write type-safe database queries while retaining the ability to use hand-optimized SQL when needed.
