Prisma vs TypeORM

Quick verdict

Prisma ORM is a TypeScript and Node.js ORM from Prisma Data, Inc., licensed under Apache 2.0. You describe models in the Prisma Schema Language (PSL), generate a type-safe client and manage schema changes with Prisma Migrate. Prisma 7 (stable, 7.10.0) made the Rust-free, TypeScript-based query compiler the default, requires a driver adapter for every database connection and moved CLI configuration into prisma.config.ts. Prisma 8 is a release candidate: npm's latest tag points to 8.0.0-rc.20, and Prisma says Prisma 7 will receive bug fixes and security updates for 18 months after 8.0.0 is final.

TypeORM is an MIT-licensed ORM for TypeScript and JavaScript. Entities are classes annotated with decorators such as @Entity and @Column (or defined separately with EntitySchema), and you can work in Active Record style (entities extend BaseEntity) or Data Mapper style (repositories). TypeORM 1.0 was released on 19 May 2026, after a long 0.3.x series; npm's latest tag is 1.1.1 (1 September 2026) and 0.3.31 is published under a legacy tag. The project announcement names a steering group, a technical lead and other maintainers, says the team "has been shipping since late 2024", and is funded through Open Collective and company sponsorship.

Key differences

Defining the model: schema file versus decorated classes

Prisma models live in a separate schema file. From the Prisma Migrate documentation:

// schema.prisma  (Prisma Schema Language, Prisma 7)
model User {
  id    Int     @id @default(autoincrement())
  name  String
  posts Post[]
}

TypeORM entities are TypeScript classes. From TypeORM's Active Record vs Data Mapper guide (Data Mapper style):

// user.entity.ts  (TypeORM)
@Entity()
export class User {
    @PrimaryGeneratedColumn()
    id: number
    @Column()
    firstName: string
    @Column()
    lastName: string
    @Column()
    isActive: boolean
}

TypeORM's getting-started guide requires TypeScript 4.5 or later with experimentalDecorators and emitDecoratorMetadata enabled, and the reflect-metadata shim imported at startup. Teams that prefer not to use decorators can define entities as EntitySchema objects in separate files. Prisma needs no decorators but adds a generation step: in Prisma 7 the client is generated to an output path you set, not into node_modules.

Querying: generated client versus repositories, Active Record and QueryBuilder

Prisma Client queries are objects describing the result you want:

// Prisma Client (Prisma 7)
const users = await prisma.user.findMany({
  where: { name: { startsWith: "A" } },
  include: { posts: true },
});

TypeORM offers two patterns. In Data Mapper style you go through a repository; in Active Record style the entity extends BaseEntity and has the methods itself. Both examples are from the TypeORM documentation:

// TypeORM: Data Mapper
const userRepository = dataSource.getRepository(User)
const timber = await userRepository.findOneBy({ firstName: "Timber", lastName: "Saw" })

// TypeORM: Active Record (User extends BaseEntity)
const users = await User.find({ skip: 2, take: 5 })

For anything more complex, TypeORM's QueryBuilder is closer to SQL:

// TypeORM QueryBuilder
const firstUser = await dataSource
    .getRepository(User)
    .createQueryBuilder("user")
    .where("user.id = :id", { id: 1 })
    .getOne()

TypeORM's docs say Data Mapper "helps with maintainability, which is more effective in larger apps", while Active Record "helps keep things simple which works well in smaller apps". In our view, Prisma's single API is easier to learn, while TypeORM suits developers used to class-based ORMs such as Hibernate or Doctrine. Either way, it helps to understand the SQL underneath; see the SQL joins guide.

Migrations and rollback

Prisma Migrate compares your schema with the migration history and writes a plain SQL file per migration. prisma migrate dev creates and applies migrations in development and prisma migrate deploy applies them in production. There are no automatic down migrations: Prisma documents generating a down script with prisma migrate diff, running it with prisma db execute and marking the migration as rolled back. Prisma 8 introduces new CLI commands, so check the version-specific docs.

TypeORM migrations are TypeScript classes with an up and a down method. migration:generate creates one from the difference between your entities and the database, migration:create makes an empty one, migration:run applies pending migrations in timestamp order, and migration:revert runs down on the last executed migration (call it again to revert more). From the TypeORM documentation (PostgreSQL SQL):

// TypeORM migration
import { MigrationInterface, QueryRunner } from "typeorm"

export class PostRefactoringTIMESTAMP implements MigrationInterface {
    async up(queryRunner: QueryRunner): Promise<void> {
        await queryRunner.query(
            `ALTER TABLE "post" RENAME COLUMN "title" TO "name"`
        )
    }

    async down(queryRunner: QueryRunner): Promise<void> {
        await queryRunner.query(
            `ALTER TABLE "post" RENAME COLUMN "name" TO "title"`
        )
    }
}

TypeORM also has a synchronize option that updates the schema on every start; its documentation warns: "don't use this in production - otherwise you can lose production data". Note that migration:run needs compiled JavaScript or a ts-node wrapper. For a SQL-first migration tool shared across languages, see Flyway vs Liquibase.

Databases and platforms

TypeORM supports the widest set of databases of the two: PostgreSQL, MySQL, MariaDB, SQLite, Microsoft SQL Server, Oracle, CockroachDB, SAP HANA, Google Spanner and MongoDB, plus Aurora data API types and mobile or browser drivers (React Native, Expo, Capacitor, Cordova, NativeScript, sql.js). In 1.0, MySQL and MariaDB use only the mysql2 client, SQLite uses better-sqlite3 instead of sqlite3, and MongoDB needs driver v7 or later.

Prisma 7 supports PostgreSQL, MySQL, MariaDB, SQL Server, SQLite and CockroachDB; MongoDB users are directed to Prisma 6.19. The Prisma 8 release candidate covers fewer databases for now (PostgreSQL as release candidate, MongoDB early access, SQLite experimental). Prisma also sells a managed database, Prisma Postgres, which the ORM does not require. For engine choice see MySQL vs PostgreSQL.

Release status: TypeORM 1.0 and Prisma 8

TypeORM spent years on 0.3.x. Version 1.0 (19 May 2026) removed long-deprecated APIs: Connection and ConnectionOptions are gone in favour of DataSource and DataSourceOptions; the global getRepository, getManager, getConnection and createQueryBuilder functions are removed; custom repositories via @EntityRepository are replaced by Repository.extend(); and findByIds is replaced by findBy with In. Behaviour also changed: null or undefined values in where now throw by default, and non-nullable relations load with INNER JOIN. TypeORM publishes an upgrade guide and a @typeorm/codemod package.

Prisma is in the opposite position: Prisma 7 is stable and Prisma 8 is a release candidate that npm already installs by default. Pin the version you intend to use with either ORM, and read the upgrade guide before following older tutorials.

Pricing and licensing

Prisma ORM is free and open source under Apache 2.0; Prisma's pricing page says "Prisma ORM is open source and will always be free". Paid plans cover the optional managed Prisma Postgres database and app hosting (see Prisma vs Drizzle ORM for the plan prices listed in October 2026).

TypeORM is free and open source under the MIT licence, with no paid edition. The project is funded through Open Collective and company sponsorship.

Pricing checked on the vendors' official pages on 7 October 2026. Prices change; confirm before buying.

Where each one leads

Limitations

When to choose each

When neither is right

• You want queries that read like SQL with the schema in plain TypeScript: consider Drizzle ORM; see Prisma vs Drizzle ORM.
• Several services in different languages share one database, or DBAs review every change: use a dedicated migration tool; see Flyway vs Liquibase.
• Your project is Python: SQLAlchemy with Alembic fills this role; see Flyway vs Alembic.
