Ride into the network
like you own it.
SubnetSlinger is the modern network engineer's toolkit — ping, trace, packet capture, DNS, SNMP, discovery, and an AI Deputy and Posse. The toolkit runs fully local — no telemetry, and the free tier needs no account. The AI is optional and off by default: run it locally with Ollama, or bring your own cloud key (Anthropic, OpenAI, or Gemini). No upsell ads in your face.
A modern replacement for the aging enterprise toolkits network engineers have outgrown — buy once, no subscription, every tool included, every desktop OS, no server host.
Why it exists
Get to the fix — not the tool hunt.
Every network engineer knows the drill: a new laptop, and a day gone installing every tool you can remember — plus the inside-company ones. Imagine getting it all done in 10–15 minutes — third-party software installs and all.
And it never fails — you're in the field, and the one tool you need isn't there, or your local machine just can't pull the data you're after. Troubleshooting a live issue is the worst possible time to go hunting for a tool, or for access you don't have.
It should just be baked into your desktop — not a folder of PowerShell commands and scripts to remember and run. You're more than busy: your dev time goes to new builds, team software, the enterprise stack — not to building your own toolkit. You'd build this yourself some night, if you ever had the time.
So we did — every tool a network engineer actually reaches for, already on your machine, plus a modern toolset built alongside the classics. Local-first, no server, no admin to wait on. Buy it once.
What you can do with it
Troubleshoot from anywhere — a downed lab, a client site, the edge — with nothing server-side to lean on.
Server hosts, not just client tools — most toolsets are client-side only. SubnetSlinger runs the server hosts right inside the app, so you can stand up and validate those services with no live, outside-connected network.
The whole kit in one place — ping, trace, pathping, discovery, packet capture, SSH/console, topology, drift, and more, on Windows, macOS, and Linux.
Put an AI Deputy on it — local with Ollama or your own cloud key — to dig through the results with you. Your models, your keys, off by default. Try the Deputy and Posse before you add a key: demo mode plays 15 scripted investigations on a sample network, and no AI provider is called (Windows and Linux 1.3).
Home your way — Original, Start Menu, GNOME grid, Tmux panes — or SPOG, a single pane of glass with boards for the daily check, the help desk, the engineer and the boss. Move, resize and share layouts as a small JSON file (Windows and Linux 1.3).
From finding to ticket — every result has one bar: copy, save, add it to the Case you're working or the Project you're running, ask the Deputy. Jobs walk the usual checks ("Is it the network?"). The End-of-shift report hands the day over in one file, with secrets masked (Windows and Linux 1.3).
Your data stays yours — your findings stay on your machine; the macOS and Linux downloads are GPG-signed and checksummed (macOS also Apple-notarized) and Windows installs from the Microsoft Store, so you can verify it's genuine before you run it.
It keeps growing — new tools land as the wire changes, at no upgrade fee — with a direct line to the engineer who builds it if you need one that isn't there yet.
Try it free — nine tools free forever, no account. Everything unlocks on a 30-day trial; buy once when you're ready.
The 10–15 minutes is the app and its tools. Local AI models (Ollama) download and run on your own hardware, so generation can take longer on some systems.
Bring the host side, too
Not just a client — a rack of servers in your pocket.
Most portable toolkits are client-side only. SubnetSlinger also runs the server hosts right inside the app — so you can test and validate the services themselves, entirely offline, in a segmented or air-gapped lab where the DHCP, DNS, and AAA you'd normally reach on the company or cloud side simply aren't there.
Nine server hosts on Windows, macOS & Linux — including AAA (RADIUS + TACACS+), which almost no portable toolkit ships.
Who it's for — small and mid-size teams, and the consultants and field techs who work across them, who can't justify a six-figure enterprise suite or a platform team to run it, but still need real tools and a way to put AI to work on their network.
The whole toolbelt, and then some
Over 60 tools. One toolkit.
Organized the way an engineer thinks — reachability, names, discovery, access, records.
Over 60 tools on the desktop. The exact set varies by platform — some tools suit one OS better than another. New protocols added as the wire changes.
Ride any horse
Desktop. Laptop. Phone in your pocket.
For the moments you can't reach your usual network or server-side tools — provisioning new gear, troubleshooting in the field, or building out a lab. It's the tool you need, on whatever device you've got. Buy the desktop once and it's yours on Windows, macOS, and Linux — every update included, no subscription. The iPhone, iPad, and Android apps are free companions, free for everyone.
Tool counts vary a little by platform — every desktop carries 60+ tools, and each version includes tools built specifically for that OS (native Wi-Fi scanning, OS connection tables, platform packet capture). The desktop apps carry the full toolkit; the free iPhone, iPad, and Android companions carry a focused set of around 30.
The iPad app is free for everyone, shipped as its own platform version — not a stretched-out phone build. A cellular iPad makes an ideal field-testing rig: a big screen to actually read a capture or a topology map, with its own LTE/5G path for out-of-band checks — so you can probe and diagnose from the edge of the network without tying up your phone.
