Part of the point is that it can launch a GraphiQL playground instance (which is how I use it most of the time)

You have the URL to some GQL API you need to look at, and so you run "gq" on the shell and pass the URL + flags for it to start a webserver running GraphiQL and auto-open it in your browser

At least on my setup the Playground UI likes to break under some circumstances and is rather slow. The CLI output can be easy to read once you view it with syntax highlighting, and it's trivial to pipe the output for any further processing.

This is a great project and I'll definitely check it out the next time.
