A browser-based signal-flow diagram tool for AV and broadcast engineers. Drag devices from a library, draw wires between connectors, and export a clean engineering drawing when the show goes live.
Pull a device from the library onto the canvas. Click a connector. Click another. The wire routes itself around everything in between.
SDI, HDMI, MADI, Dante, fiber, GPIO, tally, power. 17 connector types with IN / OUT / BI directions. Mismatches stay flagged, not enforced.
SVG, PNG, or a full engineering drawing with double border and title block, up to ANSI D. Hand it to a tech or roll it into a tech pack.
WireMapper was built because the AV community deserves a purpose-built tool that doesn't cost a rack. The features below are what the workflow asked for, not what a feature spreadsheet asked for.
A library of pro AV stencils ships with the app. Build your own with the drawer-based stencil editor: manufacturer, model, device ID, location, and an arbitrary set of typed connectors.
Right-angle paths only. Auto-stagger keeps parallel runs from overlapping. Routing avoids device bodies on its own. Drag a segment to override.
Group wires sharing endpoints into a single trunk with individual comb stubs. Label the conduit, adjust the stub length, unbundle at any time.
Hover any wire and click + to add a label pill near each end: one at the source, one at the destination. Double-click to edit inline. Drop a wire on empty canvas instead of a device to plant a terminus flag marking where that signal goes off-sheet.
Double border, title block, page sizes from Letter through ANSI D. Opens a print-ready window. Send to PDF from the browser, or export directly as SVG or PNG. Everything renders in true black.
Built because the alternative cost a year's worth of gigs. WireMapper is free to use. If it earns its keep on a job, kick a few bucks toward keeping the lights on.
A two-camera studio with playback, monitoring, and a feed leaving the room. Wired in WireMapper, exported as it would print. Hover over any connector for the type.
WireMapper is free to use. No seat license, no per-project fee, no upsell modal. The alternatives cost hundreds of dollars a year. This one started with a friend's complaint and grew from there. If it helped you out, consider supporting the project.
