As a Free and Open Source Software project, STINGER receives design input and code development from the original developers, users, and the broader graph analytics community. It has been used and extended under a number of government and industry funded projects. STINGER is available under the BSD license for you to use and hack on as you see fit. We are happy to accept any feedback, requests, and code that you wish to contribute. Read-only access to our Subversion repository is publicly available and frequent contributors and collaborators may request write access. Please see the download page for even more information.
