next-intl is an internationalization (i18n) library for Next.js that provides translations, ICU message formatting, date/number localization, and internationalized routing. It offers a type-safe, hooks-based API that works across App Router, Pages Router, Server Components, and static rendering.

Use cases

• add multiple languages to a next.js app
• translate react components with type-safe message keys
• format dates and numbers per locale in next.js
• localize pathnames for seo in next.js
• handle plurals and rich text with icu message syntax
• set up i18n routing with middleware in next.js app router

When to choose

• you are building a Next.js app (App Router or Pages Router) that needs multilingual support
• you want type-safe translation keys and compile-time typo detection
• you need locale-aware date, time, and number formatting without server/client mismatches
• you want localized routing and per-language pathnames

When to avoid

• your project is not built on Next.js or React
• you need i18n for a plain Node.js backend or non-web application
• you only need simple string replacement without locale formatting or routing
