LocalePack

Building a browser extension or web app? LocalePack translates your messages.json, locale JSON, or YAML files into 52 languages while preserving placeholder syntax ($PLACEHOLDER$, {{var}}, {name}), plural keys, and nested structure. No recurring subscription: pay once, download your ZIP, ship your localized app. Supports Chrome Extension messages.json, Next.js, i18next, and vue-i18n.
