What is JSON to Zod Schema?

Zod is the most popular runtime validation library in the TypeScript ecosystem. This tool generates a matching schema from a JSON sample so you can validate API responses, form inputs, or env vars without writing boilerplate. Strings that look like emails, URLs, UUIDs, or ISO datetimes get the matching Zod method automatically.
