About i18nlint

i18nlint helps teams ship correct translations. It checks your XLIFF files against their source text with 25+ configurable rules — placeholders, brackets, punctuation, duplicates, length ratios and more — and gives you a clear report in seconds, right in your browser or your CI pipeline.

Our goal is simple: catch broken translations before they reach your users. Whether you run a single check in the browser or wire i18nlint into your build, you get fast, actionable feedback so localization issues never make it to production.

Have a question or some feedback? We'd love to hear from you.
