The article presents a step‑by‑step guide to building Lingo.app, a production‑ready web application that scrapes any website and instantly localizes its content into more than 83 languages. Leveraging Next.js 15 for the framework, Tailwind CSS v4 for a polished dark‑mode UI, and the AI Website Content Localizer & Scraper Actor on Apify, the solution addresses long‑standing pain points in web localization. Traditional approaches required hiring translators, managing extensive JSON files, and dealing with fragile client‑side rendering.

By contrast, the Apify Actor performs headless browser scraping with Playwright, extracts semantic context from the DOM, and forwards only the relevant text to Lingo.dev, a specialized AI translation service. This preserves UI intent and reduces the risk of awkward translations. The architecture also includes a secure Next.js API route that protects the Apify token, enforces a 500‑character limit to control costs, and scales serverlessly via Apify’s queue system.

The result is a lightweight, responsive Next.js app that can be deployed to Vercel or any serverless platform, enabling developers to ship global applications quickly and cost‑effectively.
