Prisma Zod Generator

The most powerful Prisma generator for type-safe validation - Generate Zod schemas, React forms, TypeScript SDKs, OpenAPI docs, and more directly from your Prisma schema.

Core Features (Free & Open Source)​

Generate production-ready Zod validation schemas from your Prisma models with full customization:

Schema Generation​

  • Multiple variants: Pure models, input schemas, result schemas
  • Generation modes: Minimal (lean), Full (everything), Custom (fine-tuned)
  • Field filtering: Include/exclude specific fields with wildcard patterns
  • Custom naming: Configure naming patterns for all schema types
  • Output layouts: Single-file or multi-file organization
  • Custom Zod import: point the generated z import at zod/v3, zod/v4, or your own configured Zod instance via zodImportTarget / zodImportPath — useful for i18n error maps

Advanced Validation​

  • @zod annotations: Inline validation rules in Prisma comments, plus @zod.meta({...}) / @zod.describe("...") metadata on fields and models
  • Special types: Bytes, Decimal, BigInt, DateTime, and fully typed Json fields via @zod.import([...]).custom.use(...)
  • Relation handling: Smart defaults for nested objects
  • Aggregate support: Count, min, max, avg, sum operations
  • Optional fields: Configurable .nullish(), .optional(), or .nullable()

Why Use Prisma Zod Generator?​

✅ Eliminate drift - Your validation always matches your database schema ✅ Type safety - End-to-end TypeScript from database to API ✅ Configurable - From minimal lean schemas to full CRUD suites ✅ Production ready - Used by thousands of projects worldwide ✅ Domain-specific - Generate different schema bundles for different contexts

Getting Started​

Install the generator and the Prisma CLI as dev dependencies, plus the runtime packages:

pnpm add -D prisma prisma-zod-generator
pnpm add zod @prisma/client

Add the generator to schema.prisma. A prisma-client or prisma-client-js generator must already be present — prisma-zod-generator reads the client configuration and errors out without one:

generator zod {
  provider = "prisma-zod-generator"
  output   = "./generated/zod"   // relative to the schema file
}

Then generate:

pnpm prisma generate
