LocaleProof
Catch text overflow before localization breaks your layouts
Hi Product Hunt! I'm a frontend dev from Ukraine building on the side ~1h/day around a full-time job.
At work the same bug kept shipping: the UI looks perfect in English, then the German translation overflows the button in production. Nobody had a tool to see it *before* handoff — so I built one.
**LocaleProof** simulates worst-case translations right in Figma (pseudo-locale + real expansion ratios for the languages you pick) and flags exactly which layers overflow, with a clickable report and one-click restore. 100% free, 100% client-side — nothing leaves Figma.
There's a sister plugin too — **CopyProof** (copy QA: empty layers, lorem ipsum leftovers, double spaces).
I'm validating a Pro tier (whole-file checks, RTL preview, report export) through a waitlist: https://localeproof-pro.vercel.app
Would love your feedback: what localization bugs bite your team the most?
how does it handle languages with really long text like german or finnish when the original strings are already tight in a fixed-width container?
