**multifeed** is a lightweight Node.js library that bundles several Hypercore feeds into a single “multi‑writer” instance: feeds you create locally are writable, while feeds received from peers are read‑only. It lets developers create, manage, and replicate any number of Hypercore logs with a simple API, making it useful for peer‑to‑peer applications that need synchronized, append‑only data across multiple writers (e.g., collaborative tools, distributed databases, or any app built on the Hypercore protocol).
