Unity Localization

What Unity Localization does

Unity's official Localization package for string and asset localization, with Smart Strings for plurals and placeholders, pseudo-localization, and import or export to XLIFF, CSV and Google Sheets. It is listed in our Localization category.

Pricing and free tier

Unity Localization is listed as free. Plans change often, so confirm on the official site before you pay.

Best use for beginner game devs

We rate Unity Localization 3/5 for beginners, which makes it usable by beginners with a little patience. Official and free, but the tables and settings take a tutorial or two to learn.

Best for: Unity games that need more than one language. The package is free to add from the Package Manager (checked Oct 23, 2026); your Unity Editor plan terms still apply.
