Build and host decentralized blogs and websites on your Mac
Planet is a free and open source tool for publishing and following web content. It doesn't rely on a central server or service, and instead uses IPFS for peer-to-peer content distribution. You can also 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 way.
