![OpenWebRX](http://blog.sdr.hu/images/openwebrx/screenshot.png)
It has the following features:
- <a href="https://github.com/simonyiszk/csdr">libcsdr</a> based demodulators (AM/FM/SSB),
- <a href="https://github.com/simonyiszk/csdr">csdr</a> based demodulators (AM/FM/SSB/CW/BPSK31),
- filter passband can be set from GUI,
- waterfall display can be shifted back in time,
- it extensively uses HTML5 features like WebSocket, Web Audio API, and &lt;canvas&gt;.
- it extensively uses HTML5 features like WebSocket, Web Audio API, and &lt;canvas&gt;,
- it works in Google Chrome, Chromium (above version 37) and Mozilla Firefox (above version 28),
- currently supports RTL-SDR, HackRF, SDRplay, AirSpy and many other devices, see the <a href="https://github.com/simonyiszk/openwebrx/wiki/">OpenWebRX Wiki</a>.
- it has a 3D waterfall display:

- *ncat* has been replaced with a custom implementation called *nmux* due to a bug that caused regular crashes on some machines. The *nmux* tool is part of the *csdr* package.
- Most consumer SDR devices are supported via <a href="https://github.com/rxseger/rx_tools">rx_tools</a>, see the <a href="https://github.com/simonyiszk/openwebrx/wiki/Using-rx_tools-with-OpenWebRX">OpenWebRX Wiki</a> on that.

## OpenWebRX servers on SDR.hu
[SDR.hu](http://sdr.hu) is a site which lists the active, public OpenWebRX servers. Your receiver [can also be part of it](http://sdr.hu/openwebrx), if you want.
