TorPaste is an Open Source Pastebin alternative whose code is available on GitHub. It has been created by Antonios A. Chariton and other GitHub Contributors and it is written in Python, using the Flask Microframework. It aims to be simple and elegant and is designed with security in mind. Moreover, the developers are trying to make it as easy as possible to set up in a HA environment.
Some of the options of TorPaste that can be enabled or disabled by the System Administrator are the ability to have a public list of all pastes, the ability to mark some pastes as private, as well as an API. For more information on TorPaste, please open the project on GitHub. Of course, Pull Requests are always welcome and we're looking forward to them.
