i18n Completeness Auditor

Audit a JavaScript or TypeScript frontend for missing translations and hardcoded UI strings before you ship a new locale.

What it flags

How to run

Point it at your source and locale files. Read-only.

Good to know

Heuristic. It recognizes t(), i18n.t(), and Trans as translation calls; custom wrappers may need a manual pass.

Questions

What is the worst bug it catches?

A missing key falling back to a raw dotted string shown to users.

Does it change anything?

No. It is read-only and flags issues for you to act on.

Ship a locale that is actually complete.
