Zod is a lot better than some of the alternative solutions I've seen. That said, the need for this sort of explicit validation always felt like a failure of where modern web development has taken us. It's so frustrating how full-stack development requires so many ways of describing the same shapes: JS input validation, Swagger for API definition, server-side input validation, ORM for schema conformance, and TypeScript often requiring separate definitions on server and client side. It's so tedious.
