Stikked

Stikked is an Open-Source PHP Pastebin, with the aim of keeping a simple and easy to use user interface as well as providing an example application for the CodeIgniter framework which stikked is based upon. (Stikked also uses the jQuery Javascript Library.) Stikked allows you to easily share code with anyone you wish. Stikked was created for the following reasons: IRC and Private Chats were spammed. Pastebins were ugly. Pastebins were confusing. Pastebins were messy and not thought through. Stikked rethought code collaboration, by making it easy to paste code. We offer a TextMate Bundle meaning you can paste to Stikked right from TextMate.
