builds full-stack infrastructure for localizing apps, docs, and websites.
Trusted by the world’s best companies
General Translation is deployed in production apps that reach millions of global users.
Your account’s activity this week.
What translation does to a layout, the libraries you write against, the platform that holds your context, and the edge that serves the result — one system.
One button in four languages, measured by the browser rather than estimated. German runs long, Japanese runs short, and Arabic re-anchors the whole line.

widths measured at render — measureText, not typed
A layout that only fits the source string breaks somewhere near the top of this list.
Developer-first libraries for React, Next.js, and more, battle-tested in production apps with millions of users.

One term, six locales, decided once. Per-locale style rules keep the wording identical everywhere it appears.

Locales in, output path out. The CLI and every SDK read the same file.

Latin, Cyrillic, Greek, Arabic, Devanagari, Han, Hangul, Thai — joined, stacked and bidi-resolved by the browser, with per-script fallbacks in the SDK.
A global, low-latency translation CDN. Push over-the-air updates without redeploying your app.
English has two plural forms, Polish four, Japanese one. GT ships ICU plurals, so the number picks the form instead of the string.

Every once in awhile, I see a snippet of code that makes me a bit emotional.
Now is one of those moments. Internationalization went from “$%!# this” to “trivial”.
