Surfly is neither a screen sharing solution nor a purely Javascript co-browsing tool. What makes us exceptional is our unique combination of Javascript and a smart content rewriting proxy.

With this, we are able to overcome cross-domain policies, while having all elements on the site (including iframes) function correctly within the co-browsing session. This means that audio and video are synced as well. In addition, all visual updates can be efficiently captured. Our proxy approach also allows us to provide all users with a very smooth co-browsing experience that is much faster than other solutions.
