GraphQL Viewer & Client

A free, multi-language app GraphQL client.

GraphQL Viewer is a focused GraphQL playground that lives in your pocket.

Whether you're a backend engineer testing a new resolver, a frontend dev exploring an unfamiliar API, or a student learning GraphQL — this app gets out of your way and lets you query.

Everything you need to query GraphQL:

- Multi-endpoint workspace: Manage as many GraphQL endpoints as you like. Each one keeps its own URL, custom headers, and cached schema. Switch between Production, Staging, and your local dev server with one tap.

- Powerful query editor: Monospace editor with proper indentation, tab support, and JSON variable handling. Variable JSON is validated as you type so you'll never run a malformed request by accident.

- Custom headers per endpoint: Add Authorization tokens, API keys, or any custom header you need. Headers are saved with the endpoint so authenticated APIs work seamlessly.

- Schema introspection browser: One tap loads the complete schema. Browse Queries, Mutations, Subscriptions, and every Type. Tap a field to insert a ready-to-run stub into your editor with proper variable declarations.

- Schema search: Type-ahead search across the entire schema to find that one obscure field instantly.

- Saved queries: Name and store your favorite queries. Run them again with two taps.

- Auto query history: Your last 50 queries are saved automatically.
