OpenLang – AI Translation for Multilingual Websites

OpenLang is a free WordPress translation plugin for creating multilingual websites with manual translation control and optional hosted AI translation. It discovers visible frontend text at runtime, lets administrators manage translations in WordPress, and serves language-specific URLs without requiring a separate WordPress page for every language. Visitors can switch languages from the frontend while OpenLang uses locally stored translation data and caching for efficient repeat delivery. Use OpenLang when you need a multilingual WordPress plugin with translation management, a language switcher, RTL support, per-language typography, language-specific logos, CSV tools, and optional automatic translation. All features included in this package are available without a license key. WordPress Translation and Multilingual Features

Manual Translation or Optional AI Translation OpenLang works locally for manual translation management. Administrators can discover frontend strings, review them, and edit translations without enabling an external translation service. Hosted AI translation is optional. When enabled under OpenLang > Settings, OpenLang can send missing source strings to the managed translation service, receive translated text, and store translations for use on the website. Multilingual URLs, Language Switcher, and RTL OpenLang serves language-specific URLs for enabled languages and includes frontend language switching. It supports both RTL and LTR layouts and remembers locally cached translation data for repeated delivery. Per-Language Design Controls Each language can use its own typography, system or Google Fonts, uploaded webfonts, website logo, Custom CSS, and Custom JavaScript. Generated code files are stored under wp-content/uploads/vynlang/assets/. The WordPress plugin folder/slug, text domain, option keys, database tables, REST namespace, JavaScript compatibility names, and other internal identifiers remain vynlang to preserve upgrade compatibility with existing installations.
