It’s GNU Radio Companion, But In The Browser

GNU Radio Companion, the popular software-defined radio flowgraph tool, now runs directly in the browser via a project called GNU Radio World, built by Marc Lichtman (creator of pysdr.org). It preserves the familiar GNU Radio Companion interface, ships with example flowgraphs, supports common SDRs like the RTL-SDR as well as a computer's sound card as an input source, and includes recorded off-air captures for experimentation. The only noted limitation compared to the desktop version is lack of support for networked SDRs.
