Opera Software has released builds of their desktop browser with support for SPDY for all three platforms.

This special edition Opera Browser feature support for both SPDY 2 and SPDY 3.

The company said:

The good news is that we’ve been hard at work implementing SPDY support in Opera, so the big red O can also take advantage of these performance increases! Other advantages include better compatibility with all Google services (and other sites and applications that employ SPDY), and allowing developers to test their own SPDY based services with Opera. We are proud to present an experimental labs release that includes our SPDY support. Please try it out, and let us know what you think.

Opera admitted that the implementation is not yet complete and there is still much work to be done before it can be added to a stable build.

Google Chrome and Mozilla Firefox already support this tech which was originally developed by Google to fasten the loading time of secure webpages.
