Welcome to OpenDIR project. The OpenDIR is a catalog of github projects manually classified by categories. Aside from the basic information about the github project you also get actual information about date of recent commit, number of stars and other things available from Github API.
This catalog is far from to be complete. Your help are welcome. Just choose the topic you know and submit one or more github projects belonging to this topic. If there is no yet the category for the project you want to submit then just specify the desired category in the submit form.
