  • zod

    TypeScript-first schema validation with static type inference

    • Zod recently announced they were deprecating discriminated unions because it was hard to maintain given their architecture. Not only are they supported in arktype, they're supported implicitly- you don't even have to tell us what keys to look at.

  • arktype

    TypeScript's 1:1 validator, optimized from editor to runtime
