Duolangue is built for that exact case: **one site, two languages, no bloat.** No custom database tables, no settings maze, no machine-translation upsell baked into checkout. Duolangue gives you a fully working bilingual site for pages, posts and custom post types: * **Directory-based routing** — your default language at the root, the second language under its own directory (e.g. `/fr/`). A `?lang=` parameter mode is available as a fallback. * **Translated URL bases** — translate the URL base of posts and custom post types( e.g. `/projects/` `/fr/projets/`). * **Manual translation linking** — link any page, post or custom post type entry to its translation from the editor (the “Duolangue — Language” panel in Gutenberg, or a metabox in the classic editor), or unlink at any time. Nothing is ever deleted. * **Language switcher** — a `[duolangue_switcher]` shortcode plus `duolangue_language_switcher()`/` duolangue_other_lang_url()` template functions for themes, page builders and code blocks. * **Automatic hreflang** — correct alternate + x-default tags on every page, out of the box. * **Menus follow the visitor’s language** — menu items pointing at a linked page or post are swapped to its translation automatically, and a language link can be appended to the menus you choose. * **ACF-aware** — Post Object, Page Link and Relationship pickers only list content in the language being edited. * **Native admin integration** — a Language column, per-language tabs and bulk “ assign language” actions on every list screen. * **Admin language toggle** — switch the admin between your two site languages ( global setting plus an optional per-user toggle). The plugin’s own strings are translated through translate.wordpress.org. * **Page-builder friendly** — builder template post types (Oxygen, Bricks, Breakdance, Elementor, Divi, Beaver Builder) are left untouched. Every switcher link points to the **linked translation of the current page** when it exists and is published; otherwise it falls back to the **home page of the target language**. #### What Duolangue deliberately does NOT do * No third language: Duolangue is designed around a language pair, where every page has exactly one counterpart in the other language (the same in Duolangue Pro). * No custom SQL tables — everything lives in post meta and a single option. * No automatic / machine translation — you (or your translator) write the words. * No subdomain or multisite-based language setup. #### Duolangue Pro A separate commercial edition, **Duolangue Pro**, adds one-click duplication into the other language, taxonomy term translation and whole-menu translation. Everything described above is in this free plugin, with no limits. Learn more at [duolangue.com](https://duolangue.com/). ### External services This plugin includes the [Freemius](https://freemius.com/) SDK, which on activation shows an optional opt-in screen. * **What is sent, and when:** only if you click “Allow & Continue” on that screen, Freemius receives your site URL, WordPress, PHP and plugin versions, the site language, your admin name and email address, and later plugin activation/deactivation/ uninstall events. If you skip the opt-in, nothing is sent. * **Why:** to understand usage, send optional product updates by email and, if you ever purchase a Pro license, manage that account. * Declining the opt-in does not limit any feature of this plugin. * Freemius [Terms of Service](https://freemius.com/terms/) and [Privacy Policy](https://freemius.com/privacy/). ## Screenshots [⌊Settings: pick your two languages, their WordPress locales and how URLs are structured.⌉⌊ Settings: pick your two languages, their WordPress locales and how URLs are structured .⌉[ Settings: pick your two languages, their WordPress locales and how URLs are structured.

Upload the `duolangue` folder to `/wp-content/plugins/`, or install it from the Plugins screen. 2. Activate the plugin. 3. Go to **Duolangue -> Settings**, pick your two languages and their WordPress locales, choose the URL structure, then save. 4. (Optional) Go to **Duolangue -> Slugs & URLs** to translate your URL bases (this flushes permalinks on save). 5. Open any page, post or custom post type entry: the “Duolangue — Language” panel in the editor sidebar lets you set its language and link its translation. ## FAQ ### Does Duolangue support more than two languages? No. Duolangue is a bilingual plugin: its data model links each page to a single counterpart in the other language, and its URLs, menus and switcher are built on that pair. This is the same in every edition — Duolangue Pro does not add languages. For three or more languages, a multilingual plugin is the right tool. ### Does it work with any pair of languages? Yes. English–French, Spanish–German, any pair. Language codes, names and WordPress locales are fully configurable. ### Where is my data stored? What happens if I uninstall? Everything lives in standard WordPress post meta and one option — no custom SQL tables. Deactivating or uninstalling **preserves** your language assignments and translation links by default, so reinstalling restores everything. A `DUOLANGUE_REMOVE_ALL_DATA` constant is available if you want a full wipe on uninstall. ### Which content types are translatable? Pages, posts and every public custom post type. Page-builder template types are excluded on purpose; developers can adjust the list with the `duolangue_post_types` and `duolangue_excluded_post_types` filters. ### Are there limits? No. There is no cap on the number of items you translate, no time limit and no license key. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Duolangue — Lightweight Bilingual” is open source software.
