Output

import { z } from "zod";

export const RoleSchema = z.enum(["USER", "ADMIN"]);
export type Role = z.infer<typeof RoleSchema>;

export const UserSchema = z.object({
  id: z.string(),
  email: z.string(),
  role: RoleSchema,
  createdAt: z.string().datetime(),
  profile: z.unknown().nullable(),
  posts: z.array(z.lazy(() => PostSchema)).optional(),
}).strict();
export type User = z.infer<typeof UserSchema>;

export const PostSchema = z.object({
  id: z.string(),
  title: z.string(),
  content: z.string().nullable(),

export type Post = z.infer<typeof PostSchema>;

Review generated schemas before pasting them into production code.

prisma to zod

Paste Prisma model and enum definitions and FrameworkKit generates Zod schema starters with inferred TypeScript types. The v1 workflow is browser-only and optimized for reviewing database-shaped output contracts.

Supported Prisma patterns

The converter supports common Prisma scalar fields, nullable fields, list fields, enums, and relation references. Datasource and generator blocks are ignored.

String, Int, BigInt, Float, Decimal, Boolean, DateTime, Json, and Bytes.
Enum blocks become reusable z.enum schemas.
Relation fields use z.lazy and are marked optional for selected payloads.

Review before production

Generated model schemas are starters. Review Decimal precision, DateTime transport format, relation includes, Json payloads, defaults, ids, and create/update input rules before shipping.

Online Prisma to Zod vs zod-prisma and zod-prisma-types

If you are evaluating zod-prisma, zod-prisma-types, or another Prisma Zod generator, this browser converter covers fast schema review without installing a code generator. zod-prisma-types regenerates full Zod schemas, including relations and input types, as part of your build. Use this tool for instant, private conversion and the package when generated schemas should live in the repository and stay in sync on every build.

Generate zod from prisma without uploading code

Paste only the Prisma model and enum syntax you want to convert. The generator never runs Prisma, connects to a database, or sends the schema to a server, so it is safe for private or proprietary data models.

What this tool does

Generate Zod validation starters from Prisma schema models and enums without uploading project code.

Validate database-shaped output

Generate Zod schemas from Prisma models for service boundaries, API responses, admin tools, and fixtures.

Review relation payloads

Make relation fields optional in generated starters because Prisma only returns relation data when selected.

Document enum contracts

Turn Prisma enums into Zod enum schemas that can be reused in API validation code.

zod-prisma-types vs online converter

Compare the zod-prisma-types generator with a browser-only Prisma to Zod converter.

Zod to TypeScript guide

Use z.infer, z.input, z.output, and zod-to-ts when Zod schemas should produce TypeScript types.

TypeScript to Zod Converter

Convert interfaces and type aliases to Zod when the source shape already lives in TypeScript.

OpenAPI to Zod converter

Generate Zod validators from OpenAPI or Swagger API contracts.

Privacy model

Prisma to Zod runs in your browser. FrameworkKit does not send tool input or generated output to a server in the current app.

FAQ

Does Prisma to Zod execute my Prisma schema?

No. FrameworkKit parses supported Prisma model and enum syntax in the browser without running Prisma, database clients, generators, or project code.

How are Prisma relation fields handled?

Relation fields are generated with z.lazy and marked optional because Prisma relation objects are only present when a query includes or selects them.

Does the converter create Prisma create/update input schemas?

No. This v1 workflow creates output-oriented model validators. Create and update input schemas need separate decisions for defaults, ids, relation connects, and write-only fields.

How are Decimal, DateTime, Json, and Bytes mapped?

Decimal maps to z.number() with a precision warning, DateTime maps to z.string().datetime(), Json maps to z.unknown(), and Bytes maps to z.instanceof(Uint8Array).

How is this different from zod-prisma-types?

zod-prisma-types is an npm package and Prisma generator that regenerates full Zod schemas, including relation and create/update input types, on every build. FrameworkKit is a browser-only converter that turns pasted Prisma models into Zod starters instantly without installing a generator. Use zod-prisma-types when generated schemas should live in your repo and stay in sync, and use this tool for fast, private conversion and review.

Can I generate Zod from a Prisma schema without installing anything?

Yes. Paste your Prisma models and enums and the converter generates Zod schema starters in the browser. Nothing is installed and the schema is never uploaded to a server.
