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 Anthropic key for the cloud. 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.
The frontier problem
The gear got smarter. The tools got scattered.
The old way
A licensed desktop toolset — one per seat, pricey and dated. But it lived on your own machine and was always there the moment you needed it.
The new way
Powerful centralized platforms and automation. But they live on a server. Can't reach it — or the admin who runs it is busy — and you're stuck without the tool or the help.
The gap
The engineer provisioning new gear, troubleshooting in the field, or building out a lab who needs the tool right now — on the machine in front of them, not behind a server or a support ticket.
SubnetSlinger bridges the gap.
Built by a network engineer who kept hitting that wall. Every tool a working engineer actually reaches for, carried with you on your own machine — no server to reach, no admin to wait on. New protocols get added as the wire changes; and legacy needs stay covered — when you still need to watch raw packets, the built-in Capture tool does exactly that: filter down to just the traffic you care about, and export straight to Wireshark.
AI is opt-in: run it locally with Ollama and nothing leaves, or use your own cloud key — your choice, depending on the model you pick.
The six-shooter, and then some
35+ tools. One toolkit.
Organized the way an engineer thinks — reachability, names, discovery, access, records. And a game.
35 tools + the Subnet Slinger arcade game. New protocols added as the wire changes.
