DrawNet.ai vs Microsoft Visio for network documentation
Visio is the incumbent and costs a subscription. DrawNet.ai is free for personal use, browser-based, and knows what a port is.
What Microsoft Visio is
Visio is the diagram tool most IT departments already own, and the format most clients expect to receive. Its stencil libraries are enormous, it integrates with the rest of Microsoft 365, and for anything that is not a network it remains a reasonable default.
Where the two differ
Visio requires a Microsoft 365 subscription from $13/month, it runs on the desktop, and — like every general-purpose tool — it treats a switch as an icon rather than as a device with 24 ports. Its connector snapping is also its most complained-about feature when you are trying to keep a bundle of links straight and anchored to the right point.
DrawNet.ai costs nothing, opens in a browser tab with no account, and draws the ports. When you need to hand the result to someone who lives in Visio, it exports .vsdx — so the deliverable stays compatible without the licence.

When Microsoft Visio is the better choice
- Your organisation standardises on Visio files as the editable source, not just as a deliverable.
- You need the breadth: floor plans, process flows, org charts, engineering schematics.
- You are already paying for Microsoft 365 and the network diagram is a small part of what you draw.
When DrawNet.ai is
When the question you need the diagram to answer is “which physical port is that on?”. Documenting a rack, a patch panel, a floor of a building, a ship or a factory line — anywhere the ports themselves are the information, and the diagram has to replace the spreadsheet rather than sit next to it.
