When doing GraphQL development, it's essential to have a tool to easily test queries and mutations. With automatic schema discovery, autocomplete, the possibility to use headers and variables, this tool makes that really easy.
On top of that, code generation and even the possibility to test subscription makes this my number one tool for working with GraphQL queries, mutations and subscriptions.
The ability to share your playground with other team members with the click of a button makes the development workflow even more smooth.
