Hyperyarn is an Open Source experimental Multi-Protocol Realtime Communication Client Server Application and Live Coding Environment. Hyperyarn facilitates realtime communication leveraging P2P (Peer-To-Peer) technology, i.e. through DHT (Distributed Hash Table) lookups in order to decentralize discourse and enable exchange of shared files inside the Hyperyarn UI (User Interface) with a built-in file browser and DCC (Direct Client-to-Client) protocol support. As a Live Coding Environment, Hyperyarn includes a self-modifying source code editor, compiler, virtual machine and debugger with network support for collaborative and performative programming projects. Hyperyarn provides cross platform support for computational systems and mobile devices and is released under the GNU GPL.
