A GraphQL Playground Contentful App
If you're using Contentful's GraphQL API you might be looking for a way to quickly set up GraphQL Playground to query you data right from within the Contentful UI.
Contentful Apps allow you to extend and adjust the interface to make it fit your needs. I wrote an app to render GraphQL playground as its own page or as a modal component right in the Contentful UI. Enjoy and happy querying!
