Prisma is an open-source database toolkit for TypeScript and Node.js back ends, best known for its type-safe ORM, declarative schema language, generated client, and migration tooling. It has since expanded into data and agent infrastructure for AI-era applications.
The official site provides quickstart guides, versioned documentation, a schema reference, migration and seeding workflows, connection guides for PostgreSQL, MySQL, SQLite, and other databases, plus examples, blog posts, and release notes.
It suits backend engineers who want compile-time checked database queries, small teams standardising schema changes across environments, and developers building data-heavy services or agent tooling that needs a reliable typed data layer.
Compared with writing raw SQL it improves type safety and day-to-day productivity, though complex analytical queries may still need hand-written statements; compared with heavier full-stack frameworks it focuses narrowly on the data access layer.
Pin the ORM and client versions together, review generated migrations before applying them to production, keep connection strings and credentials outside source control, and regenerate the client after every schema change.
