Website translation for React and Next.js applications
LingoJs can translate visible React and Next.js interfaces through a browser snippet that detects initial and dynamically added text. It is a practical option for fast deployment and non-developer review; code-first i18n remains better for compile-time control, server-only content and offline applications.

Built for your workflow
Who it is for
React and Next.js teams deciding between a managed website layer and repository-owned locale files.
Fast implementation
How it works
Load the LingoJs snippet once in the application shell, initialize it with a project key, and configure languages in the dashboard. Exercise client-side routes and conditional screens so visible text can enter the review workflow.
The challenge
One workflow.
Every language.
A full i18n refactor requires extracting strings, choosing message keys, adding locale routing and keeping translation files synchronized. That control is valuable, but it may be excessive for a marketing site or a quick market test.
Why LingoJs
Everything your team needs to go global.
No string extraction is required for the initial integration.
A MutationObserver detects text added during client-side updates.
Translations are editable outside the codebase.
Language preference can be remembered in the browser.
The integration can add language alternate links based on project settings.
A great fit if…
- You need a multilingual proof of concept quickly.
- Content owners should work without pull requests.
- Most target content is visible in the browser DOM.
- Your team can run browser tests across client-side routes.
Check this first
- Server-only metadata and content not rendered in the DOM require explicit handling.
- Hydration, streaming and route transitions should be tested on the actual application.
- Use a code-first library when locale messages must be available before JavaScript or enforced by TypeScript.
Clear answers
Frequently asked questions.
Does LingoJs replace next-intl or react-intl?
It can replace string extraction for some browser-rendered sites, but it does not provide the same compile-time and server-rendering model as a code-first library.
Does it detect content after a React state change?
The snippet observes DOM mutations and processes newly added or changed text.
What should be tested before launch?
Test initial load, client navigation, modals, forms, validation errors, metadata, language URLs and behavior with an empty browser cache.
