i18next is a very popular internationalization framework for browser or any other javascript environment (eg. Node.js, Deno).
i18next provides:
- Flexible connection to [backend](https://www.i18next.com/overview/plugins-and-utils#backends) (loading translations via xhr, ...)
- Optional [caching](https://www.i18next.com/how-to/caching), user [language detection](https://www.i18next.com/overview/plugins-and-utils#language-detector), ...
- Proper [pluralizations](https://www.i18next.com/translation-function/plurals)
- Translation [context](https://www.i18next.com/translation-function/context)
- [Nesting](https://www.i18next.com/translation-function/nesting), [Variable replacement](https://www.i18next.com/translation-function/interpolation)
- Flexibility: [Use it everywhere](https://www.i18next.com/overview/supported-frameworks)
- Extensibility: eg. [sprintf](https://www.i18next.com/overview/plugins-and-utils#post-processors)

> **Pro Tip:** Looking for a way to manage your translations? [Locize](https://www.locize.com?utm_source=i18next_readme&utm_medium=github&utm_campaign=readme) is the official service by i18next's creators — drop in [`i18next-locize-backend`](https://github.com/locize/i18next-locize-backend) for CDN delivery, AI translation, and no redeploys for copy changes. **[Free plan](https://www.locize.com/pricing?utm_source=i18next_readme&utm_medium=github&utm_campaign=readme)** available for small projects.

> **Starting from zero?** `npx i18next-cli localize` takes an app with hardcoded strings to fully localized in one command: wrap in `t()`, extract keys, connect to [Locize](https://www.locize.com?from=i18next_readme__localize) and AI-translate. [Read the launch post](https://www.locize.com/blog/i18next-cli-localize?from=i18next_readme__localize).
