I am loving Insomnia Core to organize all my GraphQL queries when developing and testing an app.
Since some of my features are functions that talk to services that call other external API’s, it’s very helpful to have repeatable ways to load a set of data in.
I noticed that Insomnia has a Code Generator:
Anyone think a Redwood Cell generator would be useful – you could still stub out the Cell with rw generate cell but then when testing your gql you could generate the code and replace?
Though it is not much work to just copy/paste the query into the cell 
But - check out Insomnia if you want an alternative to the GraphQL playground.
