Lovalingo is a managed runtime translation layer for Lovable, React, and Next.js apps. It loads centrally managed browser translation bundles, supports locale UX, and removes hand-maintained JSON dictionaries for AI-generated apps built with Lovable, v0, Claude Code, Bolt, Base44, and Mocha.

Is Lovalingo a Weglot alternative?

Yes. Lovalingo is a Weglot alternative for React, Next.js, and Lovable developers. It offers managed browser translation, per-project pricing that starts free, unlimited words under fair use, and a package-based app workflow instead of a generic website-script workflow.

How does Lovalingo compare to next-intl?

next-intl requires you to create and maintain message files for each language. Lovalingo instead loads managed browser translation bundles and reports new rendered text, avoiding hand-maintained translation keys, JSON dictionaries, and extraction workflows.

How does Lovalingo compare to react-i18next?

react-i18next is a powerful open-source library that uses project-owned translation resources. Lovalingo moves that dictionary work into managed browser translation bundles and runtime miss handling, trading code-owned messages for a hosted translation workflow.

What makes Lovalingo different from Weglot?

Lovalingo is tailored to Lovable, React, Next.js, and TanStack Start workflows, while Weglot supports a broader set of website platforms. Compare them on framework setup, locale routing, raw-HTML SEO, translation controls, reliability, and pricing. Lovalingo's current differentiator is centralized runtime translation without hand-maintained JSON dictionaries.

Does Lovalingo work with Lovable, v0, Bolt, Base44, and Mocha?

Yes. Lovalingo can be installed in the React output from Lovable, v0, Claude Code, Bolt, Base44, and Mocha. The browser runtime uses the core provider; framework-owned locale routes and raw SEO output still need to be implemented and verified in the generated app.

How much does Lovalingo cost?

Lovalingo is priced per project: Starter is $0/month forever, Start-up is $9/month, and Global is $29/month. All plans include unlimited words under fair use. Upgrade to unlock more target languages, browser SEO controls, exclusions, and priority support.

What languages does Lovalingo support?

Lovalingo supports 10+ languages including English, French, German, Spanish, Italian, Portuguese, Dutch, Chinese (Simplified), Arabic, Japanese, Hindi. More languages are being added regularly.

Does Lovalingo work with Next.js App Router?

Yes. Lovalingo includes setup paths for Next.js App Router and Lovable projects built on TanStack Start. The browser runtime handles translation and locale UX; raw locale HTML, canonical, hreflang, metadata, sitemap, and translated body output must be implemented and verified through the host framework.

Does Lovalingo affect my site's SEO?

Lovalingo supports locale-prefixed URLs and can inject canonical and hreflang tags in the browser. For reliable international SEO, verify that your framework also returns the correct locale URL, translated content, metadata, canonical, hreflang, and sitemap entries in crawlable output.

How does Lovalingo reduce translation flash?

Lovalingo uses cached translation bundles and a loading overlay to reduce visible source-language transitions. Because the public runtime translates in the browser, test cold caches, hydration, slow networks, and artifact failures on your target framework.

Can I use Lovalingo with an existing i18n setup?

You can, but running two translation systems can create conflicts. Lovalingo handles browser translation and locale UX; your framework must still own any server-rendered locale messages, routes, metadata, hreflang, and sitemap output you require.

Does Lovalingo support TypeScript?

Yes. The @lovalingo/lovalingo package is written in TypeScript and ships with full type definitions. All components and hooks are fully typed.

Can I exclude certain content from translation?

Yes, on the Global plan ($29/month). You can specify content exclusions — elements, selectors, or text patterns that should not be translated. This is useful for brand names, code snippets, and proper nouns.

How does automatic translation work?

Lovalingo scans rendered UI content in the browser, loads cached translations from its CDN, observes later DOM changes, and reports misses. Locale URLs and SEO signals still need a framework-specific integration and raw-HTML verification.

Is there a free trial?

The Starter plan is free forever — not a trial. You get 1 target language and unlimited words at no cost. Paid plans add more languages, remove the badge, and unlock browser hreflang controls; raw SEO remains a host responsibility.

What is hreflang and do I need it?

Hreflang is an HTML attribute that identifies language or regional equivalents. Start-up and Global include browser hreflang controls, but your host framework should render and verify the full reciprocal cluster in raw HTML or the sitemap.

Does Lovalingo work with Supabase or other backends?

Yes. Lovalingo translates the frontend React layer only. It is completely independent of your backend — whether you use Supabase, Firebase, PlanetScale, or a custom API. Your database, auth, and storage remain unchanged.

Can I use custom translations to override AI output?

Yes. You can override AI-generated translations for specific strings through the Lovalingo dashboard. Custom translations are persisted and take priority over automatic AI output.

How do I get support?

The Start-up and Global plans include email and website support. You can also visit our Help Center at lovalingo.com/help or contact us at help@lovalingo.com. The Starter plan has community support only.

Lovable i18n and React Weglot Alternative

Automatic i18n for Lovable, React, and Next.js apps

Lovalingo centralizes runtime translation for Lovable, Next.js, and React apps. Add managed translation bundles, locale UX, hreflang support, and no hand-maintained JSON dictionaries.

Designed for apps built with Lovable, v0, Claude Code, Bolt, Base44, and Mocha. New Lovable projects use TanStack Start, so their locale routes and raw SEO output must be configured in that host framework. Multi-language i18n means making your product work across languages without rebuilding every page by hand. Cached bundles and a loading overlay are designed to reduce source-language flash; cold-load and failure behavior should be verified on your stack.

What is Lovalingo?

Lovalingo is a managed runtime translation layer for Lovable, React, and Next.js apps. It loads browser translation bundles, supports locale UX and hreflang, and avoids hand-maintained JSON dictionaries. Raw locale HTML and SEO output remain framework-specific.

Unlike traditional i18n tools that require developers to maintain JSON translation files, Lovalingo translates content automatically into 10+ languages. It is built for Lovable, v0, Bolt, Base44, Claude Code, Mocha, React, Next.js, and TanStack Start builders who want multilingual UX without a localization rebuild.

Best-fit buyer	Problem	Lovalingo fit
Lovable, React, or Next.js founder	Needs multilingual UX without slowing product shipping	Managed browser translation; host routing and raw SEO remain explicit.
Lovable, v0, Bolt, or Base44 builder	Generated app has no clean localization workflow	Agent-assisted provider setup paired with TanStack-owned locale output.
Growth-minded product team	International SEO needs language URLs and hreflang	Paid plans add hreflang support; raw multilingual SEO still depends on the host integration.

Install Lovalingo for this app. If this is a Lovable project generated with TanStack Start, preserve TanStack routing and server rendering. Configure crawlable locale routes and SEO in the host app, then mount the Lovalingo browser runtime from the core export. If this is a legacy React/Vite project, use the standard React provider path. npm install @lovalingo/lovalingo For standard React apps, wrap your app: import { LovalingoProvider } from '@lovalingo/lovalingo/core'; function App() { return ( <LovalingoProvider publicAnonKey="your_public_anon_key" defaultLocale="en" locales={["de", "es", "fr", "it"]} // defaultLocale auto-included routing="path" > <YourApp /> </LovalingoProvider> ); } For Next.js App Router, do not statically import the package into a server layout. Dynamically import @lovalingo/lovalingo/core after hydration from a client provider, wrap it in an error boundary that preserves the English source app, and use seo={false} when Next.js owns the head. For Lovable TanStack Start apps, implement and verify raw html[lang], canonical, hreflang, translated metadata, sitemap entries, and translated body output through the host framework. Treat the Lovalingo package as the browser translation and language-switching layer.

Why Developers Choose Lovalingo Over Weglot & i18n

AI coding tools like Lovable, v0, Claude Code, Bolt, and Base44 generate features fast. Lovalingo adds managed runtime translation, locale UX, and translation controls without hand-maintained dictionaries.
