A certain type of WordPress plugin is silent. It doesn’t sponsor conferences, purchase advertisements on developer podcasts, or bombard your inbox with onboarding emails as soon as you install it. Among them is Polylang. However, if you walk into practically any WordPress agency in Paris, Madrid, or Buenos Aires, you’ll find someone who has been using it for years and probably has a quiet opinion about why it’s superior to the alternatives.
A portion of the story is revealed by the numbers. There are more than 800,000 active installations, a 4.7 rating, and fifty built-in languages. However, in an ecosystem where most tools come and go in eighteen months, statistics hardly ever explain why a plugin lasts fifteen years. When Polylang first launched in 2011, using WordPress’s own taxonomy system rather than bolting on custom database tables meant either hiring a developer or battling WPML’s more complex architecture. This decision has kept Polylang afloat. Even now, that decision pays off in terms of compatibility, performance, and how little the plugin affects the server.
You’ll hear the same kind of comment from anyone who has managed a multilingual website. It feels like a native interface. The workflow doesn’t feel like you’ve installed anything when you add a language or translate a post. WordPress seems to have always done this. That’s more difficult to engineer than it seems, which may be why agencies continue to select Polylang despite clients requesting more modern, eye-catching options.
More is handled by the free version than most websites will ever require. Posts, pages, media, categories, custom post types, RSS feeds, RTL scripts, traditional menus, and widgets can all be translated. Depending on how serious the SEO goals are, the URL structure can be set by language code, subdomain, or full domain. Language switchers are available as blocks or widgets. This is practically the entire job for a blogger who publishes in two languages. For nothing.

The Pro tier is where things get interesting and the business quietly makes money. Ninety-nine euros a year, or about $114 before taxes. Tighter integration with the block editor, machine translation via DeepL—which is more important than it may seem—translatable template sections in Full Site Editing themes, shared URL slugs across languages, and translation of slugs for categories and author bases are all included. The best compliment in this category is that DeepL tends to produce results that feel less like a machine and more like a weary human, as anyone who has compared automated translation engines will attest.
E-commerce is a conversation unto itself. For 99 € a year, Polylang for WooCommerce manages shop pages, product categories, attributes, and even transactional emails so that a Lisbon customer receives their order confirmation in Portuguese rather than English. Additionally, a free WPML to Polylang migration plugin is available, which is the kind of action that conveys confidence. They wager that once people make a change, they won’t go back.
It’s not flawless. Complex custom field setups can complicate advanced multilingual configurations, and human oversight is still required before anything goes live. When you use heavy content in more than five or six languages, performance may deteriorate. Even though it is less severe than that of competitors, there is still a learning curve. All of this is not concealed. The Polylang team appears to be at ease with the trade-offs, maybe because they are aware of what they created and for whom.
Observing the plugin’s development over time, it seems that Polylang has avoided the pitfall that many WordPress tools experience—the temptation to add features until the initial simplicity vanishes. It continues to accomplish its goals from 2011. These days, it just serves a much larger world.
