Linden Lab Official:Alternate Viewers
From Second Life Wiki
What is an alternate viewer?
The primary viewer for Second Life is the official Second Life Viewer, available on the main Second Life Downloads page. That page also links to the latest beta, the version next in line to become the next released Viewer.
The viewers below provide alternate means of accessing Second Life.
|Note: If you experience problems using any of the viewers below, you may be asked to try to replicate the problem using the officially supported SL Viewer release.|

Second Life Project FittedMesh Channel
Many Second Life developers, outside of Linden Lab, offer customized Second Life viewers. Please note that Linden Lab does not support third-party viewers.
Detailed information about many viewers in the Third Party Viewer Directory may be found in the Resident-maintained Downloads article.
