1. Scope: CDI (Contexts and Dependency Injection) focuses on managing bean instances within the application lifecycle, providing a dynamic mechanism for creating, storing, and destroying beans. On the other hand, JSF (JavaServer Faces) is a web application framework that specifically deals with the user interface and event handling aspects of web applications. CDI primarily manages beans while JSF focuses on user interaction.

2. Component: CDI serves as a dependency injection mechanism where components can be injected into various parts of an application. It promotes loose coupling between components, making the application more modular and easier to maintain. In contrast, JSF components are primarily UI elements like buttons, text fields, and panels, used to construct web pages' visual interface. CDI is more about managing beans, while JSF deals with the user interface components.

3. Annotation: CDI uses annotations such as @Inject, @Named, and @Qualifier to declare and inject managed beans, while JSF utilizes annotations like @ManagedBean and @ViewScoped to define managed beans with specific scopes within the JSF framework. The annotations used in CDI and JSF differ based on their specific functionalities and contexts within the application.

4. Integration: CDI acts as a basis for dependency injection in Java EE, integrating with various Java EE technologies like EJBs (Enterprise JavaBeans) and JPA (Java Persistence API). JSF, on the other hand, integrates seamlessly with other Java EE components to handle the presentation layer of web applications, often working in conjunction with CDI for managing bean instances efficiently.

5. Extensibility: CDI offers a high degree of extensibility through custom scopes, context management, and decorators, allowing developers to tailor the bean lifecycle and behavior to specific requirements. JSF provides extensibility through custom component development, converter, validator, and listener implementations, enabling developers to enhance the framework's capabilities for building complex UI components and handling user interactions effectively.

6. Lifecycle: The lifecycle management in CDI revolves around bean creation, injection, and destruction, primarily controlled by the CDI container. In contrast, the JSF lifecycle is centered around user interactions, including request processing, component tree construction, and rendering phases, providing a structured approach to handling user input and generating dynamic web content.

In Summary, CDI and JSF differ in their scope of functionality, component management, annotation usage, integration with other technologies, extensibility options, and lifecycle management within the context of Java EE applications.
