litellm - 💡(How to fix) Fix [Feature Request] Add i18n / Chinese language support for LiteLLM Dashboard

Feature Request

Please add i18n / language switching support for the LiteLLM Dashboard, especially Chinese (zh-CN).

Problem

LiteLLM has Chinese documentation mirrors, but the Admin Dashboard UI appears to be English-only. I could not find:

• A language switcher in the Dashboard
• An official Chinese language pack/plugin
• i18n configuration for the Dashboard
• Related merged PRs for Dashboard localization

For Chinese-speaking users and internal enterprise users, browser translation is usable but not ideal for daily operations.

Expected Solution

Add official i18n support to the Dashboard, for example:

• Add a language selector in the Dashboard
• Support en and zh-CN initially
• Extract UI strings into translation files
• Document how self-hosted users can configure the default language

Alternatives Considered

• Browser auto-translation
• Forking and manually translating the Dashboard frontend

These workarounds are inconvenient to maintain and can produce inconsistent translations.

Additional Context

Dashboard source appears to be under:

ui/litellm-dashboard

I checked the Dashboard frontend dependencies and did not see common i18n libraries such as react-i18next, i18next, or next-intl.

Thanks!
