GraphQL Playground
FreeExplore and test GraphQL APIs with an interactive editor
About GraphQL Playground
GraphQL flips the usual API workflow: instead of memorising endpoints, you write queries that ask for exactly the fields you want. But crafting those queries by hand is error-prone without somewhere to experiment. The GraphQL Playground gives you an interactive editor to write queries and mutations against any GraphQL endpoint and see the shaped response come back immediately.
Point it at your GraphQL URL, type a query or mutation in the editor, and run it. The response renders in a clean, readable form so you can iterate on field selection and arguments until the shape is right. It runs entirely in your browser, costs nothing, and needs no signup, making it handy for poking at a public API or validating your own schema during development.
Common uses
- Draft and refine a query's field selection before copying it into your application code.
- Test a mutation with sample variables to confirm it writes data and returns the right payload.
- Explore an unfamiliar public GraphQL API to learn what fields and types it exposes.
- Reproduce a query a client app is running to debug why it returns null for a nested field.
- Validate that a newly deployed schema responds correctly to your existing queries.

FAQ
Can I run both queries and mutations?
Yes. The editor handles queries for reading data and mutations for writing it against any reachable GraphQL endpoint.
Do I need an API key to use it?
Only if your target endpoint requires one. The playground itself is free and needs no account.
Will it work with authenticated GraphQL APIs?
Endpoints that need auth require you to pass the appropriate credentials; public endpoints work without any extra setup.
Is the response formatted?
Responses are rendered in a readable structure so you can easily inspect nested objects and lists.
Can I use GraphQL Playground on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
