This is the web page of OGUP: the "Observable Gopherspace Universe Project". OGUP features a gopher crawler engine that monitors the gopherspace and maintains an up-to-date list of known servers, as well as a gophermap interface to browse the list with a gopher client.
The public OGUP interface is reachable at gopher://gopher.viste.fr/1/ogup (a gopher client is required to access it).
All OGUP files are released under the open-source MIT license. Source code can be downloaded from the project's SVN repository:
svn co svn://svn.mateusz.fr/ogup
