Wire the whole rig.
Validate every path.

SigPath is a native, local-first diagramming app for audio-visual systems. Place devices, patch their ports, and watch cables color by connector while the signal path validates live — then derive pack & patch lists in a click.

        A live slice of the real app — drag a device to move it, click a glowing port then a matching one to patch.

        THE LEGEND

        Seven signals, one shared language.

        Every cable is colored by what it actually carries. The palette is the legend — so a diagram reads the same to you, your crew, and the next engineer.

        BUILT FOR THE RACK ROOM

        Instrument-grade, end to end.

        Connector-aware canvas

        Devices carry typed ports. Drag port to port and SigPath colors the cable by connector, then validates the mate live — flagging adapters, signal converters, and incompatible runs before they bite you on load-in.

        ⌘K to anything

        A command palette, a full equipment-database browser, and a guided create-device wizard. Build a gadget once and it lives in your personal library, ready to drop into the next show.

        Reports that build themselves

        Pack lists and patch lists derive straight from the diagram. Export the canvas to PNG, JPG, or PDF and the lists to CSV — your prep doc and your truck pack from one source of truth.

        Native macOS shell

        A real menu bar, multi-window documents, and light/dark themes that follow the system. Local-first and offline — your designs never leave the machine unless you send them.

        THE WORKFLOW

        Place. Patch. Ship.

        01

        Place devices

        Pull from the equipment database or roll your own with the create wizard. Each arrives with its real ports.

        02

        Patch the ports

        Drag port to port. The cable colors by connector and the path validates as you wire — green means good.

        03

        Ship the show

        Derive pack & patch lists, export the diagram and CSVs, and hand off a doc anyone on the crew can read.
