 In 3.0.0, Apollo serves out-of-the-box support for redux in favor of Apollo's state management. This example aims to be an amalgamation of the [`with-apollo`](https://github.com/vercel/next.js/tree/master/examples/with-apollo) and [`with-redux`](https://github.com/vercel/next.js/tree/master/examples/with-redux) examples.
 
+To inspect the GraphQL API, use its [web IDE](https://nextjs-graphql-with-prisma-simple.vercel.app/api).
