The cPRO survey platform is released as open source under the BSD ("3-clause") license.  We have the source code available, but have not really packaged it for external release.

However, we do our live development off an internal repo, and so the above repo will be a bit out of date.  Also, some project-specific functionality is not included here. But it will give you a sense of the system, and some skeletal documentation.  Contact us if you're really interested, and that will motivate us towards spending the time to bring the repo up to date, add the later documentation, etc.  Or, just check back in a bit - we'll get to this when we have time!
