LangBridge

LangBridge
Translate every plugin message on your server into your language with a single click, without editing files by hand.

Installed a plugin and all its messages are in English? LangBridge finds each plugin's message files, translates them automatically, and keeps colors, placeholders and the original format intact. Your players can also chat across languages with automatic translation.

✨ Main Features
Plugin Translation

• In-game menu (/lb) listing all your plugins and their status.
  
  
• Translates .yml files, plus .properties and .json language files.
  
  
• Protects what matters: colors (&a, &#ff0000, MiniMessage), placeholders (%player%, {0}), URLs, comments and file structure.
  
  
• Separates messages from settings: never touches materials, sounds, permissions, commands or worlds.
  
  
• Checks that the file is still valid before saving it.

️ Full Control

• Preview: review and fix translations before they are saved.
  
  
• In-game editor to fix any line.
  
  
• Glossary: fixed terms (e.g. Shop → Tienda) and words that are never translated (spawn, kit, PvP...).
  
  
• Quality check: flags suspicious lines (untranslated, much longer, different placeholders...).
  
  
• Undo and restore original, with automatic backups.
  
  
• Language packs to share reviewed translations with other servers.
  
  
• Real-time progress bar, visible to admins only.

For Players

• Chat translator: each player reads chat in their own language. Hovering shows the original message and which language it was written in (Italian, Chinese, Japanese...).
  
  
• Multi-language announcements (/lb broadcast): every player gets the announcement in their language.
  
  
• Automatic welcome message in the new player's language.
  
  
• Players can pick their language or turn chat translation off for themselves.

For Admins

• Language statistics (/lb stats): which languages your players speak, with recommendations.
  
  
• Discord notifications via webhook (finished translations, errors, announcements...).
  
  
• Commands in English, Spanish or Portuguese (configurable and editable).
  
  
• Developer API with events.

⚙️ Translation Engines

• Google Translate (default): free, no key needed.
  
  
• DeepL: higher quality. Requires an API key (DeepL offers a free plan).

⚠️ Important

• Machine translation is not perfect. That's why there is a preview, an editor, a glossary and a quality check.
  
  
• Privacy: to translate, texts (plugin messages, chat messages and announcements) are sent to the service you choose (Google or DeepL). No other server or player data is sent. If you don't want chat translated, you can turn it off in the config.
  
  
• Only messages stored in config files can be translated. Text hardcoded inside a plugin's .jar cannot be translated.
  
  
• After translating, reload the translated plugin or restart the server to see the changes.
  
  
• A copy of the original is always kept, so you can go back at any time.
