'GraphQl federation server that supports subscriptions

I'm currently evaluating different GraphQl servers in order to find one that supports subscriptions on a federated schema.

Apollo and HotChocolate don't support that. HotChocolate is going to (its on the roadmap) but I can't wait; and Apollo wants me to run a seperate subscription service which I'd like to avoid.

Anybody know of a service that allows me to use subscriptions this way, now? To be clear: I only need the federation server that supports subscriptions. The single schemas behind may still be served thru hot chocolate.

After some digging, I found this. Looks very promising. They claim to support subscriptions on federation.

have you tried https://github.com/sammysaglam/federation-with-subscriptions?

disclaimer: i am the author of this library.

it uses apollo server express under the hood, and supports federation with subscriptions. it works using schema stitching by converting federation SDL into schema-stitching SDL, allowing full gateway to microservice subscriptions support.
