How I Built a Platform to Instantly Internationalize React and Next.js Projects

“Internationalization (i18n) shouldn’t feel like punishment for wanting your app to reach the world.”

I’m a full-stack dev who builds tools to simplify complex workflows.

And this is the story of how i18nify.online was born — a platform that takes your existing codebase and makes it multilingual in minutes.

The Problem: i18n is Tedious (and Often Avoided)

You know the drill:

Install react-i18next
Wrap your app in a provider
Search and replace every hardcoded string
Generate translation keys and JSON files
Manually translate, debug, repeat...

It’s boring. It's error-prone.

And worst of all — it slows down the iteration speed devs love.

That's why most projects skip i18n… until the product is already in production and needs to go global.

So I asked myself:

What if we could internationalize React/Next.js apps automatically — without touching the terminal?

The Solution: i18nify.online

i18nify is a web-based platform that scans your project and transforms it into a fully internationalized codebase.

You upload your project, select a target language, and i18nify does the rest:

✅ Detects project type (React, Next.js, or Vite)
✅ Parses your code and identifies hardcoded texts
✅ Injects useTranslation() where needed
✅ Replaces raw strings with t('your.key')
✅ Generates structured translation JSON files

Yes, automatically.

Real-World Example

Let’s say you have a React component like this:

const Welcome = () => (
  <h1>Welcome to our website!</h1>
);

After i18nify:

Copier
Modifier
import { useTranslation } from 'react-i18next';

const Welcome = () => {
  const { t } = useTranslation();

  return (
    <h1>{t('welcome.title')}</h1>
  );
}

And it generates:

Copier
Modifier
// en/translation.json
{
  "welcome": {
    "title": "Welcome to our website!"
  }
}

All that — with one click.

🪄 What Makes i18nify Special?
No CLI or config files
Everything happens online. Just upload your project and go.

Supports modern stacks
React 18, Next.js 13/14, Vite, Server Components — we're ready.

Developer-centric UX
Built by a dev, for devs. Clear feedback, safe file parsing, smart overrides.

Free Plan available
Try it out with up to 2 projects/month, 1 language per project.

Who is it For?
Indie hackers going global

Agencies handling multi-language clients

OSS projects wanting clean i18n structure

Startups preparing for multilingual markets

Developers tired of find + replace all over the codebase

What’s Next?
Here’s what I’m working on:

GitHub integration (to auto-sync repos)

Multi-language export and inline translations

Preview + rollback system for changes

Full i18n testing suite integration

Built with Passion
This project started as a side tool for myself.
It’s now a platform I hope helps thousands of developers.
