How I Built a Complete P2P RSS Podcast App in a Single HTML File. The Plan is a single-page app that uses RSS (Really Simple Syndication) and peer-to-peer communication together with decentralized storage to serve as a podcast player, aggregator, and discovery app. It should work in all major browsers including mobile, mobile and desktop browsers. It must be free for the user (and me hopefully) and must be serverless. Your personal feed is stored directly in the regular link from your browser.
