How it works

Three simple steps to localize your react-i18next project. Upload namespace JSON, pay once, and download files ready for I18nextProvider.

01

Upload namespace JSON

Drop your locales/ namespace files (e.g. locales/en/common.json). We detect {{placeholders}} and _one/_other plural keys automatically.

02

Select languages

Choose from 52 languages. See transparent pricing based on your file size and complexity before you pay.

03

Download

Pay once via Stripe. Get a locales/ ZIP ready to pass to I18nextProvider—same namespace structure, translated values.

Built for react-i18next developers

Purpose-built for useTranslation(), I18nextProvider, and namespace JSON—not a generic translation tool.

useTranslation() namespace support

Keeps common.json, auth.json, and all namespaces aligned across every locale so useTranslation('ns') works without changes.

{{placeholder}} safety

Preserves interpolation tokens like {{name}} and {{count}} byte-for-byte—no broken strings in your React components.

Plural-key handling (_one/_other)

Handles react-i18next plural splits such as key_one and key_other so grammar stays correct across all target languages.

Ready for I18nextProvider

Download a locales/ ZIP with the same folder structure—drop it into your repo and pass it straight to I18nextProvider.

Parallel translation

All languages are translated simultaneously. Most jobs complete in under 5 minutes.

One-time payment

No subscriptions, no monthly fees. Pay once per job, download forever.

How react-i18next JSON fits together

react-i18next loads locale files via I18nextProvider. LocalePack generates all namespace files in the same structure your app already expects.

locales/ folder structure

locales/
├── en/
│   ├── common.json   ← source namespace
│   └── auth.json
├── de/
│   ├── common.json
│   └── auth.json
├── fr/
│   └── ...
└── ...       (52 locales)

useTranslation() hook usage

// locales/en/common.json
{
  "welcome": "Hello {{name}}",
  "items_one": "{{count}} item",
  "items_other": "{{count}} items"
}

// After i18next.init({ ns: ['common'] })
i18next.t('common:welcome', { name: 'Ada' });
i18next.t('common:items', { count: 5 });

Hook API

Plurals

Why not just use generic tools?

Generic translation tools break useTranslation() namespace JSON, double-brace placeholders, and _one/_other plural conventions.
