First, with this approach you're able to add authentication rules into operations, not just the schema. That is, you can inject claims from the Auth jwt into variables. This gives you a lot more flexibility than schema directives or a resolver middleware. This feature is unique to WunderGraph.

Next we're able to execute the persisted query on the edge using etags for low latency.

WunderGraph adds the capability to use @stream & @defer on top of any existing GraphQL or REST API. You don't have to change anything on your existing GraphQL server. This works especially great with Apollo federation. WunderGraph is a replacement for Apollo gateway. We support federation with subscriptions, @defer and @stream, another unique feature to WunderGraph. The generated code gives you simple to use hooks, in case of react, to fetch data or streams.

Finally the generated code is authentication aware. WunderGraph has its own OIDC server. Generated clients know if authentication is required for a specific persisted query. This way a query will wait until the user authenticates and then fire off.

I think this should be enough. I don't want to get too much into the details as there are a lot more benefits.
