How Big Tech Localizes Global Products Without Speaking Every Language

International Product Localization Strategy

Large consumer‑tech companies (e.g., DiDi Food, Meituan Keeta, TikTok) release a single product in dozens of countries. Rather than building a separate binary for each language, they maintain one codebase and vary only the displayed text at runtime.

Single Codebase Approach

The application contains placeholders for all user‑visible strings. At launch, the app determines the user’s locale (e.g., by country code or language setting) and fetches the appropriate text resources from a remote translation service.

Translation Request Workflow

Design in source language – UI/UX designers create the feature and write all copy in the native language (typically Chinese).

Submit translation request – Using the company’s global translation platform, the designer submits a ticket that includes:

Feature description

Usage scenarios

All UI copy (labels, hints, error messages, etc.)

Typical turnaround time is about two weeks.

Headquarters review – The central translation team reviews the submission. If clarification is needed, the ticket is returned to the requester for amendment.

Approval and distribution – Once approved, the request is forwarded to language‑specific translation teams (e.g., English, French, Spanish, etc.).

Translation delivery – Each team returns a translation bundle and a unique translation_key (often a URL or identifier) that references the localized strings.

Developer integration – Developers embed the translation_key into the product’s configuration (e.g., in a JSON manifest or feature flag). At runtime the app queries the translation service with this key to retrieve the correct language pack for the current locale.

Integration of Translation Keys

The translation key is a stable identifier; it does not require code changes for each language. When a new locale is added, only the translation bundle and its key need to be uploaded, and the existing binary can display the new language automatically.

Key Takeaways

Product designers do not need to perform translation themselves; clear, structured requirement documentation is sufficient.

Professional translation teams handle multiple target languages, ensuring linguistic quality and cultural appropriateness.

Separating design, translation, and development responsibilities enables rapid international rollout without maintaining separate apps per market.
