“Who drew this diagram — in 2021?”
Manual diagrams drift the moment the first cable moves. Six months later nobody trusts them, so nobody uses them.
Automatic network documentation
Your network
Your network
documents itself.
Cabley collects configurations every hour, discovers who is plugged into whom, and keeps your inventory, topology maps and IP address records true — without a single manually updated spreadsheet.

The problem Your network changed at 03:12.
Your network changed at 03:12.
Your documentation didn’t.
Network documentation is the only asset that silently rots while the network itself keeps evolving. The three ways teams keep records all fail the same way — humans forget, machines don’t.
“Which IP is actually assigned here?”
Address sheets disagree with reality. Two gateways, one DHCP pool, and a vendor with a laptop — and the spreadsheet says nothing.
“Can you show me when that changed?”
Compliance asks for evidence: current inventory, topology and who-changed-what. Reconstructing it the night before an audit never ends well.
How it works
Three steps. Zero typing.
Cabley’s robot does the paperwork. Watch it work as you scroll.

Point Cabley at your network
Deploy the collector — a small VM or container — and give it read-only credentials. It reaches out to your devices over SSH/HTTPS, never the other way around. Add your sites, you are done setting up.

Cabley collects & discovers
Every hour the document_network workflow runs: pull configs and interface states, learn who is cabled to whom from CDP/LLDP, parse VLANs, VRFs and IP addresses straight from what is configured.

Documentation stays current
Inventory, topology maps and IPAM are updated in place. Every added or removed neighbour lands in the change feed with before/after values — documentation you can hand straight to an auditor.

Features Everything a network source
Everything a network source
of truth should have.
The same data model behind NetBox, filled in by robots.
Device inventory
Every switch, router and firewall with vendor, model, software version, serial and role — collected from the devices themselves, grouped by site, location and tenant.
Topology that draws itself
Neighbour maps built from CDP/LLDP, per site, in the layout you choose. Unknown neighbours show up dimmed, so gaps surface instead of hiding.
IPAM from real config
Prefixes derived from actual interface addresses — records of what is configured, not of an allocation plan someone abandoned in 2022.
Duplicate-IP radar
The same address in one VRF on more than one interface? Cabley flags it as needs attention before it becomes 03:12 ticket folklore.
Change feed
Every discovered difference with before/after values: neighbours added and removed, interfaces flapping, addresses appearing or vanishing.
Runs & job history
Every hourly run is recorded with its steps, per-device results and timings. Documentation you can hold accountable — and replay.
Tenants & subnet rules
Service-provider style: assign prefixes to tenants automatically with subnet rules, so each customer sees only their own slice.
API & tokens
A NetBox-style data model with token-authenticated API access. Pipe your always-current documentation into dashboards, ticketing and CI.

Needs attention
10.6.0.2 appears on two interfaces in the same VRF — a conflict, unless it is a shared gateway.
15 prefixes without a tenant → apply a subnet rule
Outbound-only collector
The collector initiates every connection — to your devices and to Cabley. Nothing ever needs a hole punched into your firewall, and device credentials never leave the collector.
Read-only by design
Cabley documents your network; it never configures it. Give it the lowest-privilege read-only account your platform offers.
Hosted in the EU
Your documentation lives on European infrastructure, operated by Onsync IT ApS in Denmark. No third-party training data, no data resale — your network is yours.
Audit & NIS2 ready
NIS2 and ISO 27001 want current topology, inventory and change history. Cabley keeps the evidence warm so audit prep becomes an export, not a weekend.

FAQ
Questions, answered.
What is the difference between the plans?
Only the number of devices. Every plan — including
Free (up to 3 devices) — gets the full product: the self-hosted collector, hourly collection, topology maps, IPAM, the change feed and token-based API access. Paid plans simply raise the device ceiling, and Enterprise (minimum 300 devices at 5.50 DKK/device/month) adds SSO (SAML / OIDC) when it ships.Which vendors does Cabley support?
Any device reachable over SSH or HTTPS that speaks a CLI Cabley can parse — Cisco IOS/IOS-XE/NX-OS, Juniper Junos, Arista EOS, Aruba, Mikrotik and more are being rolled out continuously. Ask us about your specific gear — just ask.
Is it NetBox?
Cabley uses the same well-known data model — devices, sites, rack models, prefixes, VLANs, VRFs and tenants — but fills it in automatically. Think of it as NetBox with a robot intern that never forgets, never fat-fingers and never leaves.
What does the collector need to reach my devices?
The collector runs inside your network (small VM or container) and connects outbound to Cabley, plus device-by-device over SSH/HTTPS with read-only credentials. No inbound ports, no agents on your production devices.
How often is documentation updated?
The default is hourly
document_network runs — collect, discover, render. Each run records per-device results, so you always know when a device was last seen and what changed.Where is my data hosted?
On European cloud infrastructure, operated by Onsync IT ApS in Horsens, Denmark. We never use your network data for anything but your documentation.
Can I get my data out?
Yes — the full inventory, IPAM and topology are available through the token-authenticated API at any time. Your documentation should never be held hostage.
How do I try it?
Open the live demo with
demo / DemoUser123! and click around a real running instance, or write to info@onsyncit.dk and we will set up a trial with your own network.
Your next documentation update is in one run.
Point Cabley at your network tonight and open the dashboard tomorrow morning. The topology is already drawn.
