Using third party viewers

You may connect to Second Life using software released by a third-party developer. Linden Lab provides a Policy on Third-Party Viewers to promote a positive and predictable experience for all Second Life Residents. Beware of third-party viewers that are not in the Viewer Directory: they have either declined to self-certify their compliance with Linden Lab policies or been refused for noncompliance with the policies.
