Localization platforms manage the end-to-end translation workflow for software products, websites, and mobile apps. The best tools go beyond simple string translation — they handle context-aware translations, plural forms, right-to-left languages, and continuous localization that keeps pace with agile development cycles.
Evaluate based on your dev stack integration first. A tool that hooks into your CI/CD pipeline and auto-detects new strings saves more time than one with a prettier translation editor.
