Matrix.org is a Free, open source, and decentralized messaging system. One of the strong points of this system is its ability to bridge multiple protocols together into one interface.
Bridging to Freenode's IRC server is built into Matrix.org. If you already have a registered Nick on Freenode it is a simple process to associate your Matrix and Freenode accounts.
