From blank page to a documented network in 2 minutes

Add devices

The palette on the left has every device: network gear (routers, switches, firewalls, wireless APs, controllers and bridges, load balancers, SD-WAN edges, VPN gateways, LTE/cellular routers, modems/ONTs), WAN & cloud (Internet, ISP circuits, MPLS/WAN clouds, cloud providers), servers & services, endpoints, and voice gear. Four ways to add one:

Connect & edit links

Links are cables, not arrows. Drag from a device's connection dot onto another device to link them. Links are drawn as right-angle connectors by default; switch any link to straight in its settings.

Click a link and the side panel lets you set:

• Media type: Copper, Single-mode fiber OS1/OS2, Multi-mode fiber OM1/OM2, Multi-mode fiber OM3/OM4, Wireless link, WAN circuit, VPN tunnel, SIP trunk or Logical. Each uses its industry-standard color or style.
• Speed and the VLANs it carries.
• The interface at each end (e.g. Gi1/0/1 ↔ Gi0/1). Port labels are drawn at each end of the cable.

A Media type key appears on the canvas automatically, listing only the media types you've used. Del removes a selected link.

Device details

Click a device and the panel on the right shows its fields:

• Hostname, management IP, vendor/model, OS version, serial, location and notes.
• Type-specific fields: VLANs on switches, SSIDs on APs, circuit ID and public IPs on ISP circuits, DIDs on SIP trunks, and so on.

Hostname, model and serial number print beside each device icon, so the diagram documents itself.

Buildings, zones, VLANs & racks

Containers group devices the way the real network is laid out:

• Site / building, e.g. “Main Building MDF” or “IDF 2nd Floor”.
• Zone / segment, e.g. a DMZ.
• VLAN / subnet, with its VLAN ID, CIDR and gateway.
• Cloud VPC / VNet and Rack.

Drop a device into a container to put it inside; drag it out to remove it. Drag the corners to resize. Moving a container moves everything in it.

Network check

Click Check to review the whole document. It flags:

• Duplicate IP addresses, and IPs outside their VLAN/subnet's CIDR.
• The same interface used by two links.
• Devices with no links, and duplicate hostnames.
• Invalid IP addresses or CIDRs, and page links pointing nowhere.

Click any issue to jump straight to the device.

Auto-arrange

Don't bother lining things up. Click Auto-arrange and the page is laid out top-down in layers, keeping devices inside their buildings, zones and VLANs. Undo works if you liked it better before.

Document info & title block

Open Document Settings to fill in the details that print in the engineering title block at the bottom of every PDF page:

• Page title and document title.
• Site street address.
• Author, plus engineering approval: approver name and approval date.
• Last editor and last changed date.
• Page X of Y, filled in automatically.

Save & autosave

Your diagrams never leave your computer. That matters here: a network diagram holds your topology, IP plan and public addresses. Save (Ctrl+S) writes a file wherever you choose: your laptop, an encrypted share, your documentation system. Open loads a file.

The open diagram is also autosaved in your browser, on your device only, so closing the tab by accident doesn't lose work. You can turn that off or clear it from the account menu (top right). How we handle your data →

Export

Click Export and choose:

• PDF: paper sizes from Letter to Tabloid/A3. Each page carries the title block, followed by a device inventory table and a link/cabling schedule. Great for build sheets, change tickets and sign-off.
• PNG of the current page, for an email or ticket.
• CSV of devices and links, for spreadsheets.

Voice networks

The voice gear in the palette (PBX / call manager, SBC, SIP trunk provider, voice gateway, contact center platform) covers the network side of a phone system. For how calls are routed through menus, hours and queues, draw the call flow in our sister product CallSketch. The two pair well in one handover pack.
