What is CI/CD Localization?

CI/CD localization means wiring translation work into the same pipeline that builds and ships your code. Instead of localization living in a spreadsheet updated before releases, the pipeline itself extracts new keys, syncs them with the translation platform, pulls completed translations back, and runs checks that can fail the build.

The checks are the high-value part. A pipeline can verify that every key referenced in code exists in the source locale, that placeholders survive intact in every translation, that no locale has fallen below a coverage threshold, and that lang files parse. Each of those failures is trivial to catch in CI and embarrassing to catch in production.

Sync direction is a design decision: push source keys on merge, pull translations on a schedule or webhook, and decide whether translated content lands as commits or is delivered at runtime. Runtime delivery, the over-the-air model, removes the pull step entirely, since published translations reach the app without a build.
