TypeScript-first schema declaration and validation library, define types once and get static type inference and runtime validation together.
Zod lets you define TypeScript types and runtime validation schemas in one declaration, parsing data at API boundaries and automatically inferring static types from the schema. It supports complex validation, transformation, and error messages with full TypeScript integration.
Useful for TypeScript projects that handle external data, API responses, form inputs, environment variables, and file parsing. Use it to validate at runtime what TypeScript guarantees at compile time, eliminating the gap between types and reality.
