How does it pick GraphQL types?

From the values in your sample: whole numbers, decimals, text, true/false, arrays and nested objects. When array items disagree, the field is made optional or widened.

Can I generate other languages?

Yes. Change Language to TypeScript, Go, Python, Pydantic, Java, C#, Rust, Kotlin, Swift, Scala, Ruby, Dart, PHP, Zod, GraphQL or Protobuf.

No. Bracely runs entirely in your browser, so nothing you paste or open leaves your device.
