translate-kit is an open-source CLI that automates internationalization for Next.js apps. Run `npx translate-kit init` and it will: - Scan your JSX/TSX and extract every translatable string - Generate semantic keys with AI (not random hashes) - Transform your code to use next-intl's t("key") calls - Translate everything to your target locales Build-time, Zero lock-in, not runtime = No client-side SDK, no loading spinners. The output is static JSON files and standard next-intl code.
