useContext vs Redux — When Each Is the Right Tool

Context is preferable for frequently-changing granular state because it batches updates automatically, while Redux is better suited for static configuration values.

Context is best suited for infrequently-changing values consumed broadly (e.g. theme or auth), since every consumer re-renders on change, while Redux excels at frequently-changing state where components need to subscribe to only the specific slice they use.

Redux and Context are functionally interchangeable in all cases; the choice is purely a matter of team preference and file organization.

Context should always be preferred over Redux because it requires no boilerplate and provides selector-based subscriptions out of the box.
