[edit] Source Code Repository Access

OpenSimulator uses git as its source code repository. 

git clone git://opensimulator.org/git/opensim


See Source Code Repository for more details.

See Using Git for more Details on installing and using GIT with OpenSimulator.org

You can also browse the source code for OpenSimulator using a web browser.

opensim-libs git repository contains the source code to some of the 3rd party libraries built and included in OpenSimulator.

libOpenMetaverse contains the source code of libOpenMetaverse for versions >= 0.9.1.0 ( the code for dotnet 6 needed for OpenSimulator 0.9.3.0 is on its branch dotnet6 )
