OpenWebRX is a multi-user software-defined radio (SDR) receiver with a web interface, providing browser-based demodulation (AM/FM/SSB/CW/BPSK31), a waterfall display, and support for RTL-SDR, HackRF, SDRplay, and AirSpy devices. It uses HTML5 features like WebSocket and Web Audio API to stream compressed audio and waterfall data to multiple clients.
Use cases
- share an SDR receiver over the web for multiple users
- listen to AM/FM/SSB/CW radio in a browser
- run a remote RTL-SDR receiver with waterfall display
- host a public web-based SDR receiver
- monitor radio spectrum remotely
When to choose
- you want a browser-accessible multi-user SDR receiver
- you need waterfall display and demodulation over WebSocket
- you use RTL-SDR, HackRF, SDRplay, or AirSpy hardware
When to avoid
- you need actively maintained software - development was discontinued in 2019
- you require Python 3 or security patches - it depends on Python 2.7
- you are building critical infrastructure
- consider the OpenWebRX+ fork instead
