I built a zero-dependency CLI that catches i18n drift (and knows your plural rules)

Short summary

The author built localediff, a zero-dependency CLI that catches missing translations and plural rule mismatches across locale JSON files. Unlike existing i18n tools, it's framework-agnostic, respects CLDR plural rules for 150+ languages instead of assuming English's shape, and requires no external account. Available on npm and PyPI, it integrates into CI/CD with simple exit codes and is MIT licensed.
