Zod Schema Generator
FreeGenerate Zod validation schemas from TypeScript types
import { z } from 'zod';
const schema = z.object({
id: z.number(),
name: z.string(),
active: z.boolean(),
});
type Schema = z.infer<typeof schema>;About Zod Schema Generator
Zod is a great way to validate data at runtime, but keeping a Zod schema in sync with your TypeScript types means writing the schema by hand and matching every field and type carefully. That duplication is easy to get wrong as your types evolve. The Zod Schema Generator turns a TypeScript type into a matching Zod validation schema, so your runtime validation lines up with your static types without the manual translation.
Paste your TypeScript type, and the tool outputs a corresponding Zod schema you can drop into your validation layer. It runs entirely in the browser with no signup and no upload, so it is free, private, and instant. This is useful when validating API inputs, form data, or config against your existing types, giving you a schema as a starting point that you can refine with custom rules like min, max, or regex constraints.
Common uses
- Generate a Zod schema from a TypeScript type to validate API inputs
- Create runtime validation that matches your existing static types
- Scaffold a schema for form data before adding custom rules
- Keep validation in sync when adding Zod to a typed codebase
- Produce a starting schema you can extend with min, max, or refinements

FAQ
Does it convert a TypeScript type to Zod?
Yes. Paste a TypeScript type and it generates a matching Zod schema reflecting the fields and types.
Can I add custom validation rules afterward?
Yes. The output is a base schema you can extend with rules like min, max, email, or regex constraints.
Is my code uploaded?
No. The conversion runs in your browser, so your types stay local and private.
Will it handle nested types?
Nested structures are reflected in the generated schema, though you should review the result to confirm it matches your intent.
Can I use Zod Schema Generator on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
