From the website: "Beaker is a Peer-to-Peer Web Browser, made for users to run applications independently of hosts. Using P2P Hypermedia, Beaker separates frontend apps from backend services, so that users are completely in control of their software and data."
I have not tried it yet, but the concepts of Beaker look quite similar to those of ZeroNet. Usability (as can be seen in the video) is a little higher than that of ZeroNet. I have not yet tested it, but it looks quite promising. It features the Dat Protocol which is built in and the IPFS protocol which has to have the IPFS demon running externally.
I'd really like to know the differences and similarities between this approach and ZeroNet. Feel free to discuss in the comments!
