GraphQLZero is a free, online GraphQL API that you can use to get fake data from a real backend while testing or prototyping your app. It is inspired and powered by JSONPlaceholder, serving the same dataset but in the form of a GraphQL server. You'll find it useful for learning more about GraphQL, writing tutorials, testing new libraries, and more.

First, check out the example queries and mutations that you can run right from our website. The easiest way to get started is by visiting the GraphQL API Playground, where you can see the API's docs and run queries against the real backend.

GraphQLZero is powered by JSONPlaceholder and serves the same dataset in the form of a GraphQL API. Six different types of entities exist: users, posts, comments, todos, albums, and photos. These entities are also related to each other; for example, a user has many posts, a photo belongs to an album, etc.

For more information on how to query different entities, check out the examples or dive into the full schema in the GraphQL API Playground.
