 ### 🔬 Engine Fingerprinting
 *   **Technology Identification**: Automatically identifies the underlying GraphQL engine and its technology stack
 *   **Supported Engines**: 
-  - **Apollo Server** (Node.js, JavaScript)
-  - **Graphene** (Python, Django, Flask)
-  - **Hot Chocolate** (.NET, C#)
-  - **Hasura** (Go, Haskell)
