๐Ÿ”Œ Plan the whole rig before you buy anything

Wire up your gear on screen
before you touch a cable

Diagrav is a visual planning tool for anyone wiring together audio/video gear or a DAWless synth setup. Drag devices onto a canvas, connect their ports, and let the app catch incompatible connections and total up your shopping list โ€” before you've spent a dollar.

Everything you need to plan a rig, nothing you don't

Built for the moment before a purchase โ€” when you're still figuring out what actually connects to what.

๐Ÿ–ฑ๏ธ

Drag-and-drop canvas

Place devices from a library of ports and connectors, then draw cables between them exactly like you would on a whiteboard โ€” except it remembers everything.

โœ…

Real compatibility checking

Every connector type knows what it physically mates with. Try to wire an XLR into a 1/4" jack and the app tells you why not, instead of finding out at the store.

๐Ÿงพ

Automatic shopping list

Every cable and device on the canvas rolls up into a bill of materials โ€” grouped by cable type and length, with running costs, so you know exactly what to order.

๐ŸŽš๏ธ

Multi-cable bundles

A stereo pair or an 8-channel snake is really one purchase, not several. Bundle the individual runs together so the shopping list counts it the way you'd actually buy it.

๐Ÿ“š

A growing shared library

Connector types, cable types, and device templates are shared across everyone using the app โ€” with your own private additions for anything niche or proprietary.

๐Ÿค

Share & collaborate

Share a diagram with view or edit access, keep a version history as it evolves, and pick up right where you left off.

The canvas

See your whole signal path at a glance

Drop a device onto the canvas, expand it to see its individual ports, and drag a connection from one port to another. Every wire is a real object โ€” it knows which two ports it joins, what cable type it needs, and how long a run it is.

  • Devices collapse to a compact view when you don't need the detail
  • MIDI, audio, video, network, and power connectors, side by side
  • Bundle related runs (like a stereo pair) into one visually distinct cable

The shopping list

A bill of materials that updates itself

As you wire things up, Diagrav keeps a running bill of materials in the side panel โ€” every cable type you'll need, grouped by length, with a running cost total. Bundled cables count as the single item you'll actually order.

  • Cables grouped by type, then by length, so you know exactly what to buy and how many
  • Device and cable costs roll up into one grand total
  • Anything missing a cost is flagged, never silently treated as free

The library

A device catalog that grows with you

Browse built-in devices and connectors by category or manufacturer, search across everything at once, and drop in your own custom gear when something isn't in the catalog yet โ€” synths, mixers, adapters, whatever your rack actually has.

  • Organize by category or by manufacturer, whichever matches how you think
  • Add your own devices and connector types in minutes
  • Submit your additions back to the shared catalog for everyone else to use
