Prisma Has a Free ORM for TypeScript — Type-Safe Database Access with Auto-Generated Queries

A TypeScript developer wrote raw SQL queries. No autocomplete. No type checking. A typo in a column name only showed up at runtime, in production.

Prisma is a TypeScript ORM that generates type-safe database clients from your schema. Every query is autocompleted and type-checked at compile time.

What Prisma Offers for Free

• Type-Safe Client - Auto-generated from your schema
• Prisma Studio - Visual database browser
• Migrations - Declarative schema migrations
• All Databases - PostgreSQL, MySQL, SQLite, MongoDB, SQL Server, CockroachDB
• Relations - Elegant relation handling
• Aggregations - Count, avg, sum, min, max
• Raw SQL - Escape hatch when needed
• Prisma Accelerate - Connection pooling and caching (free tier)

Quick Start

npm install prisma @prisma/client
npx prisma init

// schema.prisma
model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?
  posts Post[]
}

model Post {
  id       Int    @id @default(autoincrement())
  title    String
  author   User   @relation(fields: [authorId], references: [id])
  authorId Int
}

const users = await prisma.user.findMany({
  include: { posts: true },
  where: { email: { contains: '@gmail.com' } },
})
// Fully typed! Autocomplete works!
