FAQ

Can I run GraphQL queries here?

Use the request builder to POST to your GraphQL endpoint with a JSON body containing query and variables.

Does it support subscriptions?

Browser clients are best for query and mutation over HTTP. Subscriptions usually need WebSockets and a dedicated client.

Why am I seeing CORS errors?

The target server must allow your origin. For local servers, use a tunnel or enable CORS during development.

Is this tool free?

Yes. No login is required for the built-in HTTP client workflow.
