Both Context API and Redux are used for state management, but they are quite different in purpose, flexibility, and complexity.

Aspect	Context API	Redux
Purpose	Share simple global state	Manage complex state logic and side effects
Boilerplate	Minimal	High (needs actions, reducers, store setup)
State updates	Localized (Context Provider updates)	Centralized (dispatch actions, reducers handle updates)
Middleware support	Not built-in	Rich ecosystem (e.g., redux-thunk, redux-saga)
DevTools	Limited	Excellent (Redux DevTools for time-travel debugging)
Learning Curve	Easy	Moderate to steep
Use Case	Themes, auth status, user preferences	Large apps needing complex state flows

When to use which?

• Use Context API when:

  • You have a small to medium-sized app.
  • You need to share simple state like user authentication, app theme, or language settings.

• Use Redux when:

  • You have a large app with complex state logic.
  • You need features like time-travel debugging, middleware, or advanced performance optimizations.

Final Thought:

Context API is simpler and built into React — ideal for sharing simple, global data.
Redux is powerful — better suited for big apps with complex, structured data flow.
