What is Graphpeek?

GraphPeek is a Chrome DevTools extension that captures every GraphQL request your app makes, parses operations by name and type, and provides instant access to authorization headers. It solves the problem of GraphQL requests hitting the same /graphql URL by displaying operation names, types, status codes, and timing at a glance. Designed for developers debugging GraphQL traffic in Apollo, urql, Relay, and Hasura applications.
