Bright Canopy http://www.brightcanopy.com/ Bright Canopy
We render SecondLife and OpenSim on powerful machines and stream it straight to your device
Because we run your viewer on a powerful cloud machine, you can view SL and OpenSim at the highest settings even from a low-end PC, phone , tablet, or Chromebook.
For Pre Launch we will be support only Chrome Browser and will not support mobile platforms. This is to allow us to focus on core features with a solid resident experience before we add mobile. Other viewers and mobile devices actually already work in our testing, but mobile will require viewer UI tweaks. We also plan to take advantage of Frame’s new native clients to get even more awesome performance.

Third party viewers that support mesh http://bit.ly/HVHXSI Third party viewers that support mesh
This is update 2 on viewers that now support mesh for Second Life.
Mesh has already changed the look of Second Life drastically and the rate seems to be speeding up. I have been impressed with mesh builds so far on the grid and it’s definitely worth creating mesh objects.

Third-party Viewers listed on the Second Life Wiki http://wiki.secondlife.com/wiki/Alternate_viewers Third-party Viewers listed on the Second Life Wiki
Third-party Viewers are those which have been created by developers not working for Linden Lab. These Viewers offer altered or additional functionality compared to the official Second Life Viewer.
BleedingEdge viewer. http://nicholaz-beresford.blogspot.com/ BleedingEdge viewer.
The BleedingEdge viewer is the one of my viewers which despite the long time makes most sense if you have a performance challenged machine, because it comes without the Windlight rendering.
My SL viewers are vintage versions. They are still operational (in line with latest essential security and protocol changes), but based on 2007/2008 Linden viewers and they are probably only of interest to folks who run SL on underpowered computers or who dislike changes which LL made since mid 2008.
PyOGP http://wiki.secondlife.com/wiki/PyOGP PyOGP
Pyogp is an open source project between Linden Lab and the Architecture Working Group (AWG) to support testing the Open Grid Protocol (OGP).
Written in Python, Pyogp will consist initially of a client library and test functionality to enable testing OGP-enabled virtual worlds such as Second Life and compatible OpenSim implementations. These components will expand as the effort matures.
WindLight (Second Life) http://wiki.secondlife.com/wiki/WindLight WindLight
WindLight is the code name for Second Life "physically-accurate atmospheric rendering & lighting" project, which graduated from a "First Look" technology preview to a Release Candidate viewer, then eventually was included in the 1.19.1 main SL viewer.
