About Lang Forge
From the official readme · v1.0.41Description
Lang Forge is a modern multilingual plugin that handles multilingual URL routing (4 URL formats), manual post and string translation, a language switcher, hreflang SEO, RTL layouts, a glossary, WooCommerce, unlimited languages, and one-click migration from WPML / Polylang / TranslatePress. It ships a REST API and WP-CLI commands and is a drop-in WPML compatibility layer. AI translation is available as the Lang Forge Pro add-on.
Switching from WPML, Polylang or TranslatePress?
Lang Forge imports your existing setup instead of making you start over. The migration tool reads your current plugin’s data and recreates it: translated posts and their language links, string translations, taxonomy translations, and your language URL structure.
The migration is non-destructive. Your current plugin stays installed and untouched until you confirm the result, so you can compare both side by side and roll back if anything looks wrong.
If you are coming from WPML, you can also keep your existing theme and plugin code working unchanged. Lang Forge ships a WPML compatibility layer that implements the functions third-party code expects — icl_object_id(), icl_get_languages(), icl_get_current_language() and icl_get_default_language() — so integrations built against WPML keep working without edits.

External services
Every outbound request this plugin makes is listed below. Activating it, and opening its screens, contacts nobody.
This plugin contacts no external service. Translation, the language switcher, string translation, hreflang and migration run on your own site, and the plugin has no analytics, no telemetry and no licensing calls of its own. AI translation and quality checks belong to the separate Lang Forge Pro add-on, which describes the services it uses in its own documentation.
Installation
- Upload
langforgeto/wp-content/plugins/, or install via Plugins → Add New. - Activate the plugin.
- Go to Lang Forge → Settings and enable your target languages.
- (Optional) AI translation comes with the separate Lang Forge Pro add-on; the add-on adds its own Connect screen.
Frequently asked questions
How do I make my WordPress site multilingual?
Install Lang Forge, go to Lang Forge → Settings and add the languages you need. Pick how language URLs should look — subdirectories like /fr/, a query parameter, subdomains, or a separate domain per language. From there every post, page and custom post type gets a Language panel where you link or create its translations.
How do I translate WooCommerce products and categories?
Lang Forge translates WooCommerce product content, product categories and tags, and store strings such as cart and checkout labels. Open any product in the editor and use the Language panel the same way you would for a post.
How do I add hreflang tags to WordPress?
Lang Forge outputs hreflang tags automatically in wp_head for every translated URL, including the x-default entry, and generates an hreflang sitemap. No manual markup and no separate SEO plugin configuration needed.
Can I use a separate domain for each language?
Yes. Domain mapping is one of the four supported URL formats, alongside subdirectories, subdomains and query parameters. You can point example.fr and example.de at the same WordPress install and Lang Forge will serve the correct language on each.
How do I migrate from Polylang without losing translations?
Run the built-in migration tool. It imports your translated posts, the links between them, your string translations and your language URL structure. Polylang stays installed and untouched until you confirm the migration, so nothing is lost if you change your mind.
Can I migrate from WPML?
Yes, and your existing code keeps working. Beyond importing your content, Lang Forge provides a WPML compatibility layer implementing icl_object_id(), icl_get_languages() and related functions, so themes and plugins written against WPML continue to work without modification.
Will my URLs change if I switch from TranslatePress?
Only if you want them to. The migration tool reads your current language URL format and reproduces it, so existing links and search rankings stay intact. You can change the format later from Settings if you decide to.
Does it support right-to-left languages like Arabic and Hebrew?
Yes. Lang Forge includes RTL support for Arabic, Hebrew, Persian, Urdu and Kurdish, switching text direction and adjusting the admin and switcher layout automatically.
How do I add a language switcher to my menu?
The switcher is available three ways: as a widget, as a shortcode you can drop anywhere, and in the admin bar. It can display flags, native language names, or both.
How do I translate strings from my theme or another plugin?
Any string passed through WordPress translation functions is registered automatically via gettext and appears in the String Translation screen, where you can translate it per language. No .po file editing required.
Can I translate my site from the command line?
Yes. Lang Forge ships WP-CLI commands for listing languages, linking and unlinking translations, importing and exporting translation data, and running bulk operations — useful for staging deployments and scripted workflows.
Is there a way to export translations to XLIFF or CSV?
Import and export of XLIFF and CSV files is available in Lang Forge Pro, for sending content to external translators or translation agencies.
How many languages can I use on the free version?
Unlimited. There is no plan-based cap on the number of languages in the free version.
Does Lang Forge work with my theme?
Yes. Lang Forge uses standard WordPress hooks — the_content, get_the_title, hreflang via wp_head — so no theme-specific integration is needed.
Does it work with Elementor and ACF?
Elementor and ACF field translation is available in Lang Forge Pro. The free version handles standard post content, custom post types and taxonomies.
Does it slow down my site?
Basic translation, the language switcher, string translation and hreflang all run locally with no external requests. This plugin sends nothing anywhere. The separate Pro add-on, if you add it, lists its own requests in its readme.
Is AI translation included in the free version?
No. The free version covers manual translation of posts, strings, taxonomies and WooCommerce content. AI translation, translation memory and bulk AI translation are part of the Lang Forge Pro add-on.
How much does AI translation cost?
AI translations consume Forge Credits (separate from the subscription). One credit ≈ one short paragraph. Credits don’t expire.
Is my content sent to OpenAI?
Not by this plugin; AI translation is a feature of the separate Pro add-on, which lists its own requests in its readme.
What is a glossary and when do I need one?
A glossary locks specific terms to a fixed translation — brand names, product names, industry terminology — so they stay consistent across every translated page instead of varying between passes.
Changelog
Deleting the plugin leaves the job queue shared by the Forge plugins alone while another one is still installed. If you run Lang Forge Pro, it must be 1.1.4 or newer.
1.0.41
- Deleting the plugin leaves the job queue the Forge plugins share in place while another Forge plugin or add-on is still on the site. The check used to miss add-ons, and Rank Forge installed from wordpress.org, so the queue could be dropped while a neighbour still had jobs in it.
- Settings no longer shows the Translation Model card: this package has no AI translation, so the card had nothing to describe.
1.0.40
- This release needs Lang Forge Pro 1.1.4 or newer if you run the add-on. The licence screen, the upgrade prompt and the upgrade banner moved into the separate Lang Forge Pro add-on; this plugin only notes which features the add-on provides, with a link to its product page. An older add-on stays switched off until it is updated, and an admin notice names both versions and where to download the add-on. Translations already saved are untouched.
- String Translation shows no AI Translate button unless the add-on runs AI translation — no locked button. One line says where AI translation comes from.
- Settings and Tools no longer link to an upgrade: AI translation, Translation Memory and one-click site duplication say that they come with the add-on.
- The screens the add-on provides (Visual Editor, Analytics, Translation Memory, Import / Export) name it, with a link, instead of showing a locked page.
1.0.39
- Glossary opens with no licence check. It has always been part of this plugin, and the menu no longer puts it behind a gate that could only answer yes.
- The PRO badge in the menu and in the section tabs marks a screen the Lang Forge Pro add-on provides and this site does not have. It follows whether the add-on is installed, not the licence.
- The String Translation help shows the [langforge_string] shortcode. The old [lf_string] form keeps working in existing content.
1.0.38
- Fixed: on a site without WPML or Polylang, the first activation made Russian the default language and added English under /en/, whatever language the site was written in. A fresh install now starts with the site’s own language (Settings → General → Site Language) as its only language, so an English site stays English; add more languages under Lang Forge → Languages.
1.0.37
- This release needs Lang Forge Pro 1.1.0 or newer. An older add-on is switched off whole rather than left running, because beside this core it would be present and wrong rather than absent. Until you update it AI translation, bulk AI translation, translation memory, translation QA and the frontend editor are unavailable. Translations already saved are untouched, an admin notice names both versions and what stopped, and installing the current add-on brings all of it back.
- Deleting the last Forge product on a site now clears the job queue the Forge plugins share — its table, its two scheduled events and its version marker. While any other Forge product is still installed, deleting this one leaves the queue exactly as it is, because the pending jobs in those rows are that product’s too.
- Fixed: Lang Forge → Tools stopped with a fatal error on a site whose licence includes bulk duplication while the Pro add-on is not loaded. The card shows the Pro teaser instead.
1.0.36
- No change in this package: the release updated parts that ship only in the edition distributed through avakode.com.
