The GraphQL Playground helps developers test and debug their queries with ease. Unlike many online clients that log your queries and tokens, our playground respects your privacy — requests go directly from your browser to your endpoint. Nothing is stored. Whether you are testing a new API endpoint, debugging a query issue, or exploring an unfamiliar GraphQL schema, this playground provides a full-featured environment right in your browser.
What is GraphQL?
GraphQL is a query language for APIs that gives clients the power to ask for exactly what they need. It eliminates over-fetching and under-fetching. This playground lets you experiment with field selections, nested relationships, and argument variations before writing a single line of frontend code.
How to Use
- 1Set the endpoint: Enter your GraphQL API URL in the top field.
- 2Compose your query: Write your query or mutation — supports fragments and aliases.
- 3Define variables: Optionally provide dynamic arguments in JSON format.
- 4Execute and analyze: Click "Run Query" and view the JSON response with clean formatting.
Technical Workflow
When you click "Run Query," the tool sends an HTTP POST request with a JSON payload containing query and variables keys. This is the same workflow used by Apollo or Relay. Note that CORS must be enabled on your endpoint for browser-based clients.
Why Use This Tool
Unlike other GraphQL playgrounds that send your queries and schema to external servers, this tool processes everything locally. Your API endpoint is called directly from your browser, and your schema exploration stays private. The built-in documentation panel makes it easy to discover available queries, mutations, and types without leaving the editor.
Tips for Developers
Start by pasting your GraphQL endpoint URL and fetching the schema. Use the documentation explorer to understand available types. Test queries with variables before integrating them into your application code.
