Lovable Supported Languages: Complete 2026 Reference

Quick answer: Lovable.dev can generate UI in the language you prompt, and new Lovable projects use TanStack Start with SSR. But Lovable still does not replace a full i18n layer for runtime language switching. Lovalingo adds managed browser translation without JSON dictionaries; configure and verify locale routes and raw SEO in the generated app.

Does Lovable support multiple languages?

Yes, in two different senses, and the distinction matters.

  1. Generation language: Lovable's chat interface and AI prompts accept and produce any language. You can ask Lovable in French, Spanish, German, Italian, Portuguese, Japanese, Chinese, Arabic, Hindi, Persian, Korean, Vietnamese, Turkish, Polish, Dutch, Swedish, and dozens more — Lovable will generate the React UI in whatever language you describe.

  2. Runtime multilingual app: This is the question most people are actually asking. New Lovable projects use TanStack Start with SSR, while older projects may still use React/Vite patterns. The generated code does not include a full i18n layer, a language switcher, translated metadata, or locale-prefixed URLs. To support runtime language switching for end users, you need to add an i18n layer after generation.

What languages can my Lovable app support in production?

With Lovalingo added to a Lovable app, the following languages are supported out of the box:

  • English
  • French
  • German
  • Spanish
  • Italian
  • Portuguese
  • Dutch
  • Chinese (Simplified)
  • Arabic (with RTL support)
  • Japanese
  • Hindi

More languages can be enabled via the Lovalingo dashboard. Right-to-left scripts (Arabic, Hebrew, Persian/Farsi, Urdu) are handled correctly.

How to add 10+ languages to a Lovable app

Paste this prompt into your Lovable chat:

Install @lovalingo/lovalingo and add multilingual support.

1. npm install @lovalingo/lovalingo
2. Detect whether this Lovable project uses TanStack Start or legacy React/Vite.

For TanStack Start:
- preserve TanStack Start routing and server rendering
- mount the Lovalingo browser runtime from @lovalingo/lovalingo/core in client code
- make /en, /fr, /de, /es and /:locale/* routes return HTTP 200
- server-render html[lang], canonical, hreflang, title, meta description, OG, and Twitter tags
- add the Lovalingo language switcher using TanStack navigation

For legacy React/Vite:
- wrap the root app with LovalingoProvider
- set routing="path"
- add the LanguageSwitcher component

import { LovalingoProvider } from '@lovalingo/lovalingo/core';

<LovalingoProvider
  publicAnonKey="YOUR_PUBLIC_KEY"
  defaultLocale="en"
  locales={["fr", "de", "es", "it", "pt", "zh", "ar", "ja", "hi"]}
  routing="path"
>
  <App />
</LovalingoProvider>

3. Add a <LanguageSwitcher /> in the navbar.
4. Add the Lovalingo public anon key from lovalingo.com.
5. Verify /fr, /de, /es return 200 and the initial HTML includes html[lang] and hreflang.

Ask Lovable's chat to apply the matching host integration and add the switcher, then verify the raw HTML and hydrated UI yourself. Get the free Lovalingo key at lovalingo.com (Starter plan is free forever for 1 target language).

Lovable.dev Persian language support specifically

A common search question: does Lovable support Persian (Farsi)? Lovable can generate Persian UI when prompted, but that does not by itself create runtime language switching or locale routing. If Persian is enabled in your localization setup, verify RTL behavior in the browser and implement the /fa/ route and its SEO output in the host app.

Lovable language switcher: where to put it

The recommended pattern is a <LanguageSwitcher /> component in the top-right of the navbar. With Lovalingo:

import { LanguageSwitcher } from "@lovalingo/lovalingo/core";
 
function Navbar() {
  return (
    <nav>
      {/* your navbar */}
      <LanguageSwitcher />
    </nav>
  );
}

The component is keyboard-accessible, mobile-friendly, and displays flag emojis or full language names depending on screen width.

Lovable localization vs translation: what is the difference?

  • Translation = converting text from one language to another ("Sign up""S'inscrire").
  • Localization = translation plus cultural adaptation (currency symbols, date formats, address formats, RTL layout, plural rules).

Lovalingo handles rendered-text translation and can support locale direction UX. Full localization still requires application code for dates, numbers, currencies, plural rules, images, and cultural adaptation—for example with the browser Intl APIs.

Frequently asked questions

Does Lovable have built-in i18n?

No. Lovable can generate UI in many languages and new projects use TanStack Start with SSR, but it does not replace a full i18n layer. Lovalingo can handle browser translation and language switching; the generated app must implement and verify crawlable locale routes and SEO.

Can I translate a Lovable app for free?

Yes. Lovalingo's Starter plan is free forever with 1 target language and unlimited words under fair use. The Start-up plan is $9/month per project for up to 3 languages and browser hreflang controls; raw SEO remains host-owned.

Does Lovable export the app code so I can add i18n manually?

Yes. Lovable supports code export to your own GitHub repository or local development environment. You can then add an i18n package (Lovalingo, react-i18next, next-intl, Lingui) as a normal npm package.

Will adding multilingual support break my Lovable app?

It should not if the integration preserves the generated stack and is tested. Lovalingo avoids rewriting component strings into keys, but its browser runtime still scans and updates rendered DOM, so test hydration, exclusions, slow loads, and failure fallback.

What about SEO for multilingual Lovable apps?

Lovalingo can supply browser SEO data on supported plans. For dependable indexing, configure TanStack Start to return locale-prefixed URLs, target-language content, metadata, canonical tags, hreflang, and sitemap entries in the initial response.
