The GNU Radio Companion is a [[Graphical user interface|graphical UI]] used to develop GNU Radio applications.<ref>{{Cite web |url=http://gnuradio.org/redmine/projects/gnuradio/wiki/GNURadioCompanion |title="GNU Radio Companion Wiki" |access-date=2014-08-08 |archive-url=https://web.archive.org/web/20160304022949/http://gnuradio.org/redmine/projects/gnuradio/wiki/GNURadioCompanion |archive-date=2016-03-04 |url-status=dead}}</ref> This is the front-end to the GNU Radio libraries for [[signal processing]]. GRC was developed by Josh Blum during his studies at [[Johns Hopkins University]] (2006–2007), then distributed as [[free software]] for the ''October 2009 Hackfest''. Starting with the 3.2.0 release, GRC was officially bundled with the GNU Radio software distribution.

GRC is effectively a Python code-generation tool. When a flowgraph is ''[[Compiler|compiled]]'' in GRC, it generates Python code that creates the desired [[graphical user interface]] (GUI) [[Window (computing)|windows]] and [[Graphical widget|widgets]], and creates and connects the blocks in the flowgraph.

GRC currently supports GUI creation using the [[Qt (software)|Qt]] toolkit.

=== Plotting and Displays ===
GNU Radio provides many common plotting and data visualization data sinks, including FFT displays, symbol constellation diagrams, and scope displays. These are commonly used both for debugging radio applications and as the user-interface to a final application.

=== PyBOMBS ===
Many users create "out-of-tree modules" for use with GNU Radio. To manage these, and the dependencies required to run GNU Radio, the organization created the PyBOMBS (Python Build Overlay Managed Bundle System) project.<ref>{{Cite web |url=http://gnuradio.org/redmine/projects/pybombs/wiki |title="GNU Radio Wiki - PyBOMBS" |access-date=2014-08-08 |archive-url=https://web.archive.org/web/20170211235417/http://gnuradio.org/redmine/projects/pybombs/wiki |archive-date=2017-02-11 |url-status=dead}}</ref>
