> The main downside I see is that its runtime code size footprint is much larger than Zod.

Yes, it unfortunately really does bloat your bundle a lot, which is a big reason I personally chose to go with Valibot instead (it also helps that it's a lot closer to zods API so it's easier to pickup).

Thanks for linking that issue, I'll definitely revisit it if they can get the size down.

Personally, I find Zod’s API extremely intimidating. Anything more resembling TypeScript is way better. ArkType is neat, but ideally we’d have something like:

  export reflect type User = {
    id: number;
    username: string;
    // ...
  };

Edit: just remembered about this one: https://github.com/GoogleFeud/ts-runtime-checks

It's not perfect and doesn't cover all of zods functionality (iirc coercion) but I've used https://www.npmjs.com/package/ts-to-zod before to generate zod schemas directly from types.

This is why I like libraries like typia or typebox-codegen; I'd prefer to write TypeScript and generate the validation, rather than write a DSL.
