Why Choose Lingui for Your Localization Projects?

Universal

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, including React Server Components (RSC) support.

Powerful Tooling

Manage your intl workflow with the Lingui CLI, Vite plugin, and ESLint plugin.

The CLI extracts, compiles and validates messages, while the Vite plugin compiles catalogs on the fly, and the ESLint plugin helps catch common usage errors.

Full Rich-Text Support

Seamlessly use React components within localized messages, without any restrictions. Creating rich-text messages feels just like 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 their keys are used.

Headache-Free Professional Localization

Candidate knows 1 language, but Candidate knows 10 languages.

No need 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.

Battle-Proven & Future Proof

Over the past few years, we have seen a lot of localization projects and developed a tool to handle them all.

If your team needs to edit source texts without developer involvement, or you want the ability to deliver the most recent translations directly to your customers – we've got you covered.

Suitable for All Localization Platforms

Integrate Lingui with your existing workflow. It supports both explicit and auto-generated message keys.

Translations are stored in JSON or a standard PO file, which is supported by almost all translation tools.

Verified by Thousands of People

Lingui has been used and tested by thousands of satisfied users and has been proven to provide accurate and efficient i18n and l10n results. Join the community.

Fully Fledged

Lingui is a general-purpose framework with bindings for React (including RSC). It can be used on a server with Node.js or in Vanilla JavaScript.

Extend its functionality with optional modules for features like lazy loading of language packs, automatic user locale detection, and more.
