Hey alisson - we work with Relay apps as well, since you can see GraphQL request/responses, console logs, and a session video.

We definitely help more with Redux because you can view the client-side state at any moment. Hopefully with Relay 2 we can hook into the client-side storage mechanism and help with debugging there.

I think this should work with Apollo out of the box, which is a GraphQL client with similar features to Relay but with deep Redux integration.

(Disclaimer: I work on Apollo)
