Mobile proxy browsers are coming back. For a long time we had Opera Mini. And these days we have seen the release of Opera Beta for Android and an update to Chrome Beta for Android, both highlighting data compression features. And they are not the only ones. About a year ago Amazon introduced their Silk browser with a similar proxy solution to Google’s.
On desktop, although this feature hasn’t become that popular due to the higher bandwidth that is usually available, Opera also had presence with their Opera Turbo feature.
Opera Beta for Android is a webkit browser with an “Off-Road mode”, which is not more than an Opera Mini embedded. In fact, it states it uses Presto in its User Agent. In practice, this means they use different browser engine for the compressed and not-compressed modes, resulting in different user experiences when browser the same site depending on this mode. You can check it accessing sites like Google or Facebook.
It is tempting to just forget about optimization techniques, leaving the hard work to these proxies. The truth is that we should be the ones that optimize by default our sites to provide the best experience regardless of user’s browsers. These tools are showing us how important good performance is, especially when using mobile devices.
