What is SubnetSlinger?

SubnetSlinger is a network engineer's toolkit that runs on your machine. Your findings — inventory, incidents, logs, runbooks, the Vault — stay on it: there's no cloud sync and no account needed to use the tools.

Licensing: buying Pro is a separate thing — it means signing in with your email so we know what you own. See "Your account, your license, and your data" for exactly what that does and doesn't send.

Each tool does one job: test reachability, look up a record, scan ports, inspect a certificate, and so on.

Finding a tool: press Ctrl+Shift+P for the command palette and type a name ("ping", "wall jack", "syslog"), search the left rail, or use the Tools menu — all three find tools inside hubs too. The rail lists every tool; hubs like Security, Lab Testing, Field Kit and Local servers expand (the ▸ arrow) to show the tools inside them. Hover any tool to see a one-line description. The Home screen shows your network at a glance.

New to networking? Start with Ping (is it reachable?), then Trace and Path ping (where along the path is it breaking?). Read the "Reading results" and "Can these tools cause harm?" articles next.

Teaches or gets out of the way: View ▸ Beginner help (on by default) shows extra explanation on each tool and a first-run welcome. Turn it off for an uncluttered, expert layout — the How it works panel in each tool's header (with a link to the full doc) stays either way.
