Chupacabra enables users to archive and discuss web content free of surveilance and commercial influence. It can be used for personal research, micro-blogging, or discussing dank memes. Chupa posts are standalone archives of web content (a single HTML file with images embedded and scripts removed) and a corresponding Matrix message pointing to the mxc:// URI where the archive can be fetched. Posts can be discussed in real-time in the channel that they were shared. Behind the scenes, all post discussion is composed of replies to the post's Matrix message.
