Planet is a free and open-source native macOS application for publishing and following web content. It doesn't rely on a central server or service; instead, it uses a local IPFS node for peer-to-peer content publishing and discovery. You can link your content to an Ethereum Name (e.g., yourname.eth) so that others can follow you on Planet using your .eth name. Since both IPFS and ENS are decentralized, you can use Planet to build and follow websites in a decentralized manner.
