Scope

Tracking performance for GraphQL in development is quite hard.

I'm using the Apollo Tracing format here. Unfortunately there isn't a good viewer for the information from there. It also doesn't include SQL/Cache information.

Features:

• Viewer for tracing information
• Store tracing information on disk, for future reference
