Prisma

What is Prisma?

Prisma is a TypeScript ORM built around a declarative schema file that generates a fully-typed database client, so your queries are type-checked against your actual schema instead of relying on hand-written types that can drift out of sync. It also ships a migrations workflow for evolving your schema over time and Prisma Studio, a GUI for browsing and editing data directly. It's become the most-downloaded TypeScript ORM largely on the strength of its documentation and how smooth the day-to-day migration workflow feels.

Key features

• Declarative schema file that generates a fully type-safe query client automatically
• Migrations tooling that tracks schema changes and applies them consistently across environments
• Prisma Studio, a built-in GUI for browsing and editing your database data
• Version 7 replaced the old Rust query engine with a lighter, edge-friendly TypeScript runtime
• Broad database support (Postgres, MySQL, SQLite, MongoDB, and more) behind one API

Who it's for

A solid default for TypeScript projects that want strong type safety and a smooth migrations experience without much setup friction. If you need very fine-grained control over raw SQL or are working in a non-TypeScript stack, a lighter query builder or raw SQL might fit better.

Pricing

The core ORM is free and open-source; Prisma also offers a separate paid managed Postgres/data platform product if you want hosted infrastructure alongside it. Check the tool's site for current platform pricing.
