<p><strong>Instant website translation and SEO to grow your global traffic. Get lang prefixes, hreflang tags, and automated sitemaps for Google. No complex DNS setup needed. Launch your multilingual store or site in 60 seconds.</strong></p>
<h4>Why Proxylang</h4>
<p>WordPress translation generally takes one of three approaches:</p>
<ul>
<li><strong>Database plugins</strong>: store duplicated translated content in your database and often involve manual translation work.</li>
<li><strong>DNS proxies</strong>: require CNAME or nameserver changes that some managed hosts don’t allow.</li>
<li><strong>Browser translate widgets</strong>: translate in the visitor’s browser but aren’t indexed by search engines.</li>
</ul>
<p>Proxylang gives you real indexed per-language URLs, server-rendered SEO for search crawlers, and instant in-browser translation for visitors — with no DNS changes:</p>
<ul>
<li>Real per-language URLs (<code>yoursite.com/es-MX/about</code>) indexed by Google</li>
<li>AI translation in 68 languages with context-aware quality</li>
<li>Server-rendered translated HTML for search-engine bots (Googlebot, Bingbot, ChatGPT, Claude, Perplexity)</li>
<li>Instant client-side translation for human visitors. No page re-render</li>
<li>Auto-generated hreflang tags, per-language XML sitemaps, robots.txt</li>
<li>WooCommerce Product JSON-LD localized for Google Shopping rich results</li>
<li>Translation glossary so brand terms always render the way you want</li>
<li>Full analytics dashboard with anonymous visitor tracking, languages, countries, top pages</li>
<li>Zero DNS setup. Install plugin, paste keys, you’re live</li>
</ul>
<h4>Account required</h4>
<p>This plugin connects WordPress to the Proxylang translation network. <strong>You’ll need a free Proxylang account at <a href="https://proxylang.dev" rel="nofollow ugc">proxylang.dev</a> to use the plugin.</strong> Sign-up takes 30 seconds. The free tier translates 2,000 words/month at no cost. Enough for most small business sites. Higher tiers scale with traffic. See <a href="https://proxylang.dev/pricing" rel="nofollow ugc">proxylang.dev/pricing</a>.</p>
<h4>Who is this for?</h4>
<ul>
<li><strong>WordPress sites going international</strong>: blogs, agencies, SaaS marketing sites, portfolios.</li>
<li><strong>WooCommerce stores selling cross-border</strong>: products, variations, cart, checkout, and Product schema all translate automatically.</li>
<li><strong>Sites on managed hosts</strong> that don’t allow DNS changes: Kinsta, WP Engine, WordPress.com Business+, Pressable, and similar.</li>
<li><strong>Agencies managing multilingual clients</strong>: install once, manage translations from one dashboard.</li>
</ul>
<h4>How it works under the hood</h4>
<p>When a visitor lands on <code>/es-MX/about</code>, the plugin inspects the request:</p>
<ul>
<li><strong>Search-engine bot</strong> (Googlebot, ChatGPT, Claude, etc.): plugin fetches a fully translated HTML page from Proxylang’s edge network and serves it directly. Indexable, hreflang-annotated, no JavaScript required.</li>
<li><strong>Human visitor</strong>: plugin redirects to your source URL (<code>/about</code>) and sets a language cookie. Your page then loads with a tiny script that translates visible content client-side. No full re-render, no flicker, and your address bar stays clean.</li>
</ul>
<p>Translations are cached at 300+ edge locations and inside your WordPress install, so repeat visitors see instant translated pages.</p>
<h3>Features</h3>
<ul>
<li>AI translation in 68 languages with brand-context awareness</li>
<li>Translates both search engines and visitors. Bots see pre-rendered translated HTML, real visitors see live in-browser translation</li>
<li>Per-language <code>sitemap.xml</code>, <code>robots.txt</code>, hreflang, og:locale, content-language headers</li>
<li><strong>Translation glossary</strong>: override AI translations for brand terms or any specific phrase</li>
<li><strong>Full analytics dashboard</strong>: visitors, languages, countries, top pages, growth over time. All anonymous and aggregated</li>
<li>WooCommerce Product JSON-LD localization for Google Shopping</li>
<li>Compatible with W3 Total Cache, WP Super Cache, LiteSpeed Cache, and other page caches</li>
<li>Translation cache invalidation via signed HMAC webhooks. No manual purge</li>
<li>GDPR-friendly. No visitor PII, cookies, or form submissions sent to Proxylang</li>
<li>Works with any theme, page builder, or block editor (Elementor, Divi, Gutenberg, Bricks, etc.)</li>
<li>WordPress 6.5+ and PHP 7.4+ supported</li>
</ul>
<h3>External services</h3>
<p>This plugin connects to the Proxylang translation service. <strong>The plugin will not function without contacting these services.</strong> Translation cannot happen entirely on your server. Proxylang runs the AI translation pipeline, edge cache, and dashboard.</p>

<ol>
<li>
<p><strong>proxylang.dev</strong>: configuration, plugin registration, daily heartbeat.</p>
<ul>
<li><code>POST https://proxylang.dev/api/proxylang/plugin/register</code>: sent on plugin activation. Transmits: your public key (Authorization header), plugin version, your site’s home URL, REST webhook URL, requested mode.</li>
<li><code>POST https://proxylang.dev/api/proxylang/plugin/heartbeat</code>: sent once per day. Transmits: your public key, plugin version, mode, home URL.</li>

</ul>
</li>
<li>

<ul>
<li><code>GET https://proxy.proxylang.dev/v1/render?domain=…&path=…&lang=…</code>: sent when a search-engine bot requests a <code>/{lang}/*</code> URL. Transmits: your public key (X-Proxylang-Key header), the requesting visitor’s User-Agent (X-Proxylang-Visitor-UA header), requested path, language.</li>

<li><code>GET https://proxy.proxylang.dev/v1/script-bundle?key=…&lang=…&path=…</code>: fetched (and <code><link rel="preload"></code>-hinted) by that script to retrieve cached translations for the current page and language.

<h3>Privacy</h3>
<p>This plugin does NOT send visitor personal data, cookies, form submissions, IP addresses, or session content to Proxylang. Only the request URL path and the visitor’s User-Agent string are transmitted (the User-Agent is required so that bot translations can be metered per crawler). Logged-in administrator previews skip Proxylang entirely and serve the origin page directly.</p>
<p>Translation caches live entirely on your WordPress install (in object cache or transients) and on Proxylang’s edge network. No per-visitor records are stored. Analytics are collected anonymously and aggregated (country, language, page path) for the dashboard.</p>
<p>For European customers: Proxylang is GDPR-compliant. See the privacy policy linked above for the full data-processing agreement.</p>

Polylang

Works great for the translations of a WordPress website

Great plugin for i18n


If i need multilingual solution, only polylang


Good plugin


Faster and lighter than WPML, easy to configure and manage.


Fast, easy to use, reliable

works fine!


A few quirks here and there, but handles this complicated task very, very well, and with a good interface. 🫶


Simply marvelous


If you are using FSE then you cant translate templates and this makes the polylang useless


Not working with basic tool - native wordpress editor


The only issue is you cannot pair existing translations - or if there this feature already exists, I haven't found it. Otherwise it works well.


I am very happy with free version


Thanks to developers of this excellent work.Many filter hooks and functions to use for developers.Using built-in core tables on database is smart.


Great Work


It works very well, even with block themes, as long as it's used together with Site Editor Classic Features.



Thank you!


Works great, thank you!


Plugin cumpri com tudo que promete, simples de ser instalado e tudo que tiver duvida o forum resolve os problemas.



Vale muito a pena a versão free dele da para desenvolver muito projeto com ele.


Excelente


It does what it needs to do and is free!


Works great

Nice and easy!


This plugin works great for creating multilingual websites. I have been using it on a couple of my websites and it does its work perfectly.


Works like a charm!


Indispensable if you want to create a multilingual website. It integrates well with other plugins, eliminating unnecessary stress.


A true standard

Great plugin

Go multilingual in a simple and efficient way. Keep writing posts and taxonomy terms as usual while defining their languages all at once.
