## What it is
ts-to-zod is a CLI tool that generates Zod validation schemas from TypeScript types and interfaces. It verifies that generated schemas are type-compatible with the originals and supports JSDoc tags for extra validators.

## Use cases
- generate zod schemas from typescript types
- validate api responses at runtime with schemas derived from types
- convert typescript interfaces to zod
- keep zod schemas in sync with typescript types
- add runtime validation to a typescript codebase
- generate schemas for untrusted api data

## When to choose
- you already use TypeScript types and want matching Zod schemas without writing them by hand
- you want guaranteed type compatibility between your types and generated schemas
- you want a simple CLI that fits into a build script or CI pipeline

## When to avoid
- you don't use TypeScript or Zod
- you need schemas for OpenAPI/JSON Schema rather than Zod
- you need a library API for in-process generation rather than a CLI
