FernSDR is a free, self-hosted WebSDR server that turns a software-defined radio and antenna into a browser-based receiver anyone with the link can listen to, complete with a live spectrum waterfall and an admin panel. It installs in one line on Linux, including a Raspberry Pi, and is built for amateur radio and SDR hobbyists who want to share a receiver with many listeners efficiently.
