## What it is
ShinySDR is a software-defined radio receiver application built on GNU Radio with a web-based user interface and a plugin system. Combined with hardware like RTL-SDR, HackRF, or USRP, it lets users listen to and decode radio transmissions remotely from a browser.

## Use cases
- listen to AM/FM/SSB/CW radio transmissions with an RTL-SDR dongle
- decode ADS-B aircraft positions and display them on a map
- monitor APRS and WSPR telemetry from a browser
- remotely control an SDR receiver over a LAN or the internet
- view a persistent zoomable waterfall display of the radio spectrum
- monitor multiple frequencies simultaneously from a tablet or phone

## When to choose
- you want a browser-based SDR receiver controllable from any device
- you need remote operation of an SDR over a network
- you want built-in decoding of ADS-B, APRS, or WSPR with map display
- you value a persistent waterfall that keeps history while zooming and panning

## When to avoid
- you need a polished, feature-complete SDR suite with active development
- you don't use GNU Radio-compatible hardware
- you need Windows-native support without setup effort
- you require guaranteed ongoing maintenance — the latest release is from 2020
