What qpwgraph is
qpwgraph is a free, open-source Linux graph manager for PipeWire, built with the Qt C++ framework and modeled after QjackCtl. Its canvas displays PipeWire nodes and their available ports, letting you connect ports of the same type and opposite directions by dragging. The graph can include audio, video, PipeWire/JACK MIDI, and optionally ALSA MIDI ports. Patchbay configurations save connections for later restoration, while exclusive mode removes connections not stored in the active configuration. qpwgraph also remembers node positions and custom names in its configuration file. A case-insensitive filter hides nodes by name or title and supports regular expressions. A merger option can match name or title prefixes when scanning the patchbay, also with regular-expression support. The 1.0.1 changelog adds command-line selection of a named remote PipeWire daemon, with PIPEWIRE_REMOTE taking precedence. It is licensed under GPL version 2 or later and has a free plan at no cost.
