The Difference Between Proxy and Snippet Based Localization

Proxy vs Snippet Based Localization

Over the past month or so, we’ve been getting the same question on several occasions which can only mean it’s time to address it on the official Bablic blog.

Let’s first define proxy-based localization and snippet-based localization so we can then differentiate between them as well as list the pros and cons of each.

Proxy-based Localization

Proxy-based localization is when all website communication between the end user’s browser and the website’s original server goes through the localization solution’s server (i.e. the proxy). For example, if localization company PRXLOCAL123 provides website translation/localization services for website then it means that the translation of content is completely done on PRXLOCAL123’s servers. So when an end user asks for a different language on, PRXLOCAL123 retrieves all of the page’s content from the server of, changes it with the localized content, and serves the content to the end user. This whole process simply means the end user is in fact not connected with but actually with PRXLOCAL123.

Snippet-based Localization (Bablic)

Snippet-based localization is when only the localized content (translated text, replaced images, videos etc.) is stored in the localization company’s server (PRXLOCAL123’s server for example) and only a simple javascript line is used on the original website ( in order to serve the localized content to the end-user.

When the end-user visiting requests a different language, his browser loads the original page directly from The browser then starts by reading the javascript snippet which contains the localization instructions. It continues by opening a separate communication channel with the localization company’s server (PRXLOCAL123’s server for example) in order to retrieve and serve the localized content, as fast as possible, to the end-user.

This means the localization is “done” by the end-user’s browser, which only combines the localized elements, meaning just text, rich media and some CSS changes, instead of having to redirect ALL of the content like on proxy-based localization.

Advantages of Proxy Localization

Requires no coding in integration – Proxy-based localization requires no change in the original website’s code.
Easier SEO solution – There’s no real difference to the search engine when Proxy-based translation is being used.

Advantages of Snippet Localization

Performance – Since only the translated elements (text, rich media, CSS) are being served by the localization company’s server, there is less data being communicated back and forth which explains faster load times and better performance.

Complete Localization – Content via Javascript (Popups, validation forms, tooltips & more) and content from Ajax (mostly DB content – offer of the day, announcement, listings & so on) usually aren’t translated when using a Proxy-based solution. Snippet-based solutions handle all of that and more.

– Doesn’t require DNS Integration – Unlike proxy-based solutions, snippet-based solutions do not require a DNS integration.

– Works on sub-domains & sub-directories – Unlike proxy-based solutions, snippet-based solutions work on sub-domains as well as sub-directories which are widely referred to as a better SEO strategy.

– No advanced SSL integration – No need for any special treatment for sites that are secured through SSL.

Clearly, snippet-based localization is the future of website translation. Its performance in terms of speed is unmatched, as well as its unique ability to achieve complete localization (including popups, validation forms, tooltips & more).
