# Overview

> Explore drop-in and headless options to add an inbox feed to your React app using the @suprsend/react SDK with JWT-based user authentication.

<Warning>
  **End of support for `@suprsend/react-inbox`. The current React SDK is [`@suprsend/react`](https://www.npmjs.com/package/@suprsend/react).**

  Inbox authentication has been upgraded from HMAC `subscriber_id` to signed JWT user tokens for better security. If you are starting fresh, install `@suprsend/react` and follow this page. If you are on the older `@suprsend/react-inbox` package, follow the [migration guide](/docs/react-migration-guide).
</Warning>

There are 2 ways in which you can implement inbox/feed functionality:

* **Drop-in components:** Pre-built UI with many customizable options which require minimal effort to build. For setup please refer [docs](/docs/react-in-app-feed).
* **Headless implementation:** For more advanced use cases where you want to build UI/UX from scratch. For setup please refer [docs](/docs/react-sdk-headless-feed).
