All GraphQL servers/implementations are supported, since the module is agnostic about the GraphQL server type - you provide the execute() function yourself. By default graphql2rest assumes Apollo Link's execute() (with node-fetch), so it supports local and remote GraphQL servers via HTTP connection out of the box. But you can wrap your server's execute function and pass it whatever arguments it expects, so any GraphQL implementation can be used.
