Sixuniform has released YOUSDR v0.1 Alpha, an RTL-SDR webinterface for Raspian / Raspberry Pi. This is a web-wrapper for the rtl-sdr softwares. Currently it commands rtl_fm, rtl_tcp and dump1090.
The software can be downloaded from its GitHub. The instructions on the GitHub page show how to set it up on a Raspberry Pi running Raspbian, but the instructions should also be valid for other Linux distributions. As the software is new the authors are welcoming any improvements and feedback.
