## What it is
next-i18next is a thin layer on top of i18next and react-i18next that handles Next.js-specific internationalization wiring, including middleware, server/client splits, and resource hydration. It supports the App Router, Pages Router, and mixed setups with locale-in-path or cookie-based language detection.

## Use cases
- translate a next.js app into multiple languages
- add internationalization to next.js app router project
- serve localized routes like /en/about in next.js
- detect user language via cookie in next.js
- use i18next with server components in next.js
- migrate a pages router next.js app to app router with i18n
- manage translation files for a react next.js site

## When to choose
- you are building a Next.js app (App Router, Pages Router, or mixed) and want i18next-based translations
- you want locale routing or cookie-based language detection handled for you
- you already know i18next/react-i18next and need Next.js wiring

## When to avoid
- you are not using Next.js (use react-i18next directly)
- you need a fully managed translation platform rather than a library (consider locize backend)
- you use a framework other than Next.js with its own i18n solution
