Use it everywhere. @lingui/core provides the essential intl functionality which works in any JavaScript project, while @lingui/react offers components for leveraging React rendering.

Powerful Tooling

Manage the whole intl workflow using Lingui CLI. It extracts messages from source code, validates messages from translators and checks that all messages are translated before shipping to production.

Full Rich-Text Support

Use React components inside localized messages without any limitations. Writing rich-text messages is as easy as writing JSX.

AI Translations Ready

For AI to do great translations for you, context is critical. Translating UI copy is difficult because it's usually a list of short strings without enough context. Lingui's localization formats allow developers to write descriptions of where and how your keys are used.

Headache-Free Professional Localization

Candidate knows 1 language, but Candidate knows 10 languages.

You don't have to know how many plurals the language has. Create a product in one language, and deliver a perfect translation to users. Lingui follows Unicode ICU standards to handle plurals, genders, and selects.
