To use Tolgee with your Next application, use React integration library together with Next i18n support.

Tolgee for React provides simple API to create multi-lingual React application. With Tolgee i18n library for React you can enjoy all Tolgee i18n features.

To see Next with Tolgee in action, check this example app.

npm i @tolgee/react

Get started!

1. Create project in Tolgee platform

Go to Tolgee Cloud app or access your self-hosted instance and create a project. Then obtain your API key.

2. Setup Tolgee integration

Install the npm packages.

npm i @tolgee/react

Prepare your next-config.js.

module.exports = {
reactStrictMode: true,
i18n: {
locales: ['en', 'cs'],
localeDetection: true,
defaultLocale: "en"

Then wrap your code with TolgeeProvider

import enLocale from '../i18n/en.json';
import csLocale from '../i18n/cs.json';
import { useRouter } from 'next/router';
import { TolgeeProvider, DevTools, Tolgee, FormatSimple, useTolgeeSSR } from '@tolgee/react';

const tolgee = Tolgee()
defaultLanguage: 'en',
apiKey: process.env.NEXT_PUBLIC_TOLGEE_API_KEY,
apiUrl: process.env.NEXT_PUBLIC_TOLGEE_API_URL,
staticData: {
en: enLocale,
cs: csLocale,

function MyApp({ Component, pageProps }: AppProps) {
const { locale } = useRouter();

const ssrTolgee = useTolgeeSSR(tolgee, router.locale);

return (
<TolgeeProvider tolgee={ssrTolgee}>
<Component {...pageProps} />

export default MyApp;

3. Use T component to translate your texts

import { T } from "@tolgee/react";

export const Component = () => {
return (
<T keyName="translate_me">Translate me!</T>

Now you are able to Alt + Click & translate your texts!
