Does this validate against a schema?

No, it only re-indents the query structure based on braces — it doesn't check field validity.

Does it support mutations and subscriptions?

Yes, any GraphQL operation with brace-delimited selection sets is supported.

What if my braces are unbalanced?

You'll see an error message indicating an unmatched brace.
