LocalePack

LocalePack is a web service that translates Chrome extension messages.json files. A developer uploads the source file, selects target languages, pays through Stripe, and downloads a ZIP containing a _locales folder with a messages.json for each chosen language. The translations are generated by AI after payment, and the site says jobs are queued and completed in minutes. It is built for Chrome extension developers rather than as a general translation tool. It parses the Chrome format, reads the description field as context for the model, and returns placeholders such as $PLACEHOLDER$ and positional $1 tokens unchanged. The site lists 52 locales including regional variants such as Spanish for Latin America and Portuguese for Brazil and Portugal. Uploads are limited to 500KB. Pricing is one time with no subscription. The site states a $9.99 minimum fee plus a per language cost that scales with file size and string length, and the final quote is calculated after the file is uploaded. Optional Priority Processing adds $5 to skip the queue and finish within one hour. A pricing estimator on the home page shows the cost before checkout. The site also publishes developer guides and success cases about extension localization.
