Source code

Here are the current released versions of OpenSim.

Please see Branches for more information on the repository branches and what they are for.

Please note: As OpenSim is still at an alpha code maturity stage, there is absolutely no guarantee that functionality works or is stable, even in the numbered releases. Certain features may not work either because the code is in rapid evolution, or because functionality expected by the Linden Labs Second Life viewer has simply not been implemented yet. However, constructive feedback is still welcomed.

Also, please be aware that OpenSim requires that you have a fair amount of technical knowledge in order to set it up.

The latest source releases are always hosted at, the current latest releases is 0.6.6 and provided as:

The only difference between the two is the archive format, the source is exactly the same.

Release Code via Git

Instead of using a source archive release, you can pull specific releases from our git repository. For more information on installing and using Git, please see Using_Git.

In each case you'll want to start with a clone:

git clone git:// opensim-0.6.6

Then all other commands are run from inside the checked out directory.

  • 0.6.6 Alpha with post-release fixes (preferred)
git checkout origin/0.6.6-post-fixes
  • 0.6.6 Alpha release tag
git checkout 0.6.6-release

Release notes

These are extracted from the subversion history log and correlated with the tagged releases. It should provide some idea of the changes between each tagged version. How ever, since the tagged releases are moved out of the trunk, the versions aren't an exact correlation. Please read and understand Release Cycle and On revisions, tags and branches before using this information.


The OpenSim project only does source based releases, which you must compile yourself. Many members of our community provide binary installers that you can used based on those source releases. Links below are provided for convenience.


  • 0.6.6 Windows Installer (Post-fixes version r9993)
  • 0.6.6 Mac OS X Installer (Post-fixes version r9993)

Older Versions Archive

All older versions of OpenSim are available from the Git repo (this includes fully converted versions of every change that existed in the subversion repository, including all old tags and branches). Please be aware that even if there is zero official support for the latest version, there's even less support for older ones. They are kept here for historical and technological reference only.

The 'official' release tags and branches are all available from:


The named branches are typically extremely experimental offshoots. Stick with recent numbered versions if you expect anything to work.

There Be Dragons Beyond This Point

If you are truly feeling dangerous, adventurous, or want to help us test the next version of OpenSim you are welcome to grab the latest unstable code out of our git master repository. Any warnings previous expressed about the alpha nature of the code go double or triple if you are running directly off of master. Never, ever, ever, never run this in production environments, it is not suitable for that unless you are very familiar with the source code, and can hot fix any piece of it (that probably means you are an OpenSim core member). Feedback and testing on the unstable tree is appreciated, as that helps us make the next release better. If this scares you from using trunk, that was intended.

If it breaks, you get to keep both pieces.

  • Latest git revision version (bleeding edge)
git clone git://
  • To checkout a specific revision

After creating the clone, chnage into the directory and:

git reset --hard ########

Where ######## is the unique hash of the version you are interested in.

Another option for obtaining the code is via subversion with our svn mirror. This mirrors all git changes since the old 10k1 changeset in subversion. It is synchronized every 15 minutes, so may be 15 minutes behind git master.

  • Latest subversion revision version (bleeding edge)
svn co opensim
