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.

Viewer list

The viewers in this first section participate in reporting crash statistics to Linden Lab, and are ordered from best to worst disconnect rate (% of sessions that end without the simulator seeing a logout).

The rate used for each viewer is that of the most used version for that viewer in the sample period (a one week sample from Monday to Sunday). Viewer must have at least 200,000 minutes of use in the sample period to be included (in order to get a reliable measure; even at that minimum there can be significant variation from week to week).

The official Linden Lab viewers are shown where they would be in this ranking using the same selection criteria.
