OpenSim Available Viewers

OpenSimulator doesn't have the client program in it. Before you can connect to OpenSim, you'll need to have downloaded one of the any OpenSim compatible clients that can connect to OpenSim.


If you find a viewer, which can connect to OpenSimulator, then please add it to the bottom of the appropriate list.

Compatibility issues

Since OpenSimulator and viewers development is done by different teams with different timing and even goals, compatibility can not be assured. To connect to an older version of OpenSimulator, you may need to use an older version of your favourite viewer, which also could limit Hypergrid capability. In this case you should consult the support of your grid or chosen viewer.

Viewers

  • FireStorm Viewer - C++ based viewer for Linux/Mac/Win. Forked from Linden lab Second Life viewer. Successor to Phoenix viewer. Currently the most widely used viewer on Second Life.
    • Firestorm VR Mod - A modification to the Firestorm Vierwer to allow use of a Virtual Reality Head Mounted Display (VR HMD).
  • Dayturn - C++ based viewer for Win/Mac only. Forked from Kokua. Dayturn source code available on Bitbucket.
  • Cool VL Viewer - C++ based viewer for Linux x86_64/Linux aarch64/Mac/Win. Forked from SL v1 viewer (former name: Cool SL Viewer, first release 2007/11/16).
  • Radegast Metaverse Client - Radegast-ng is Light client, evolution of Radagast from libopenmetaverae project.
  • Scenegate - C++ based viewer with a focus on accessibility and onboarding. With a simplified UI more suitable to just visit worlds, rather than building (but the full UI is still accessible). Forked from Alchemy.
  • Alchemy Viewer - C++ based viewer for Linux/Mac/Win. Forked from Linden lab Second Life viewer.

Beta Viewers

Dayturn for Windows and MacOS https://bitbucket.org/dayturn/

OpenSim PBR Viewers

Phoenix-FirestormOS Phoenix FirestormOS Beta 7.1.4

Cool VL Viewer stable release with PBR, ALM and forward rendering modes.

Text-only Viewers

These are lightweight viewers, which either do not offer a graphical component or where the graphical component is not used by default. The function of these viewers however is to connect to a grid, chat, manage inventory, etc. Useful on systems with low specifications or for bringing an alt (alternate avatar) online without having your main avatar log out, or to quickly take care of messages, inventory, etc.

  • Mobile Grid Client - A Second Life and OpenSimulator messaging client for your Android powered device (mobile phone, cell phone, tablet...).

Other Viewers

Some other viewers that can connect to Second Life can also connect to OpenSim. You can find them in Downloads#Second Life Wiki.

Connecting with the Linden Viewer

***NOTE***: These instructions apply to the Linden Labs viewer ONLY. Most other viewers have a more elegant method, called GridInfo protocol, to choose a grid. See the documentation for those viewers for more information.

Every OpenSim grid or instance will specify a loginuri, which is a uri of the form http://someserver:9000 (standalone mode) or http://someserver:8002 (grid mode). For instance, for osgrid, this is http://login.osgrid.org.

A list of major public grids can be found at Grid_List. OSGrid is just one of many available.

All you have to do is to pass this loginuri command line parameters to the viewer and launch with it. See this wiki page (Viewer parameters#Using Viewer Parameters) how to do that.

On OSX environments, if you have multiple viewers and multiple grids to connect to, you can try the following AppleScript (one could do something similar with a shell script). Feel free to copy and modify for your own use.

--
--  This script selects a viewer and a grid for virtual worlds.
--
--
-- Variables for the two supported viewers.  More may be added here.
--
set lindenViewer to "\"/Applications/SecondLife/Second Life.app/Contents/MacOS/Second Life\""

set emeraldViewer to "\"/Applications/SecondLife/GreenLife Emerald Viewer.app/Contents/MacOS/GreenLife Emerald Viewer\""
--
-- Variables for options to select the specified grid.  Since the viewers
-- are based on the 2nd life viewer, the options are the same for each
-- viewer.  Also, connecting to the Second Life grid is the default option
-- if no other options are provided.
--
-- Currently, four grids are supported.  More may be easily added.
--
set lindenOptions to ""

set localStandalone to " -loginuri http://vw.server.lan:9000 -loginpage http://vw.server.lan/opensim/index.html"

set localGrid to " -loginuri http://vw.server.lan:8000 -loginpage http://vw.server.lan/opensim/index.html"

set osGridOptions to " -loginuri http://osgrid.org:8002 -loginpage http://osgrid.org/loginscreen.php -helperuri http://osgrid.org/"
--
-- Display dialog and select the viewer.
--
set dialogResult to display dialog "Choose viewer:
1) 2nd Life viewer
2) Emerald viewer:" default answer "1" with title "Select Viewer" with icon 1

set option to text returned of dialogResult

if option = "2" then
	set viewer to emeraldViewer
else
	set viewer to lindenViewer
end if
--
-- Display dialog and select the grid.
--
set dialogResult to display dialog "Choose server:
1) 2nd Life grid
2) local standalone
3) local grid
4) OS Grid" default answer "2" with title "Select Grid" with icon 1

set grid to text returned of dialogResult

if grid = "1" then
	set options to lindenOptions
else if grid = "2" then
	set options to localStandalone
else if grid = "3" then
	set options to localGrid
else if grid = "4" then
	set options to osGridOptions
else
	set options to localStandalone
end if
--
-- Combine the grid and viewer and execute the result.
--
set command to viewer & options
do shell script command

Linden Viewer options

The Linden viewer has a number of other options. Some are useful, some are not. See Parameter Reference from Second Life Wiki for detail.

Alternative Connection Approaches

Via a Web Browser

You can also set up a Browser Protocol Handler which will make opensim:// links in your browser do the expected thing, and launch the right OpenSim viewer.
