SubnetSlinger

SubnetSlinger is a network engineer's toolkit for your phone — 32 tools in one app, all free. Nothing is locked, there is nothing to buy, and there are no ads. Ride the wire with the tools you reach for every day: - Ping, Traceroute, and Path ping — check reachability and find where a path breaks - Discovery — sweep your subnet and watch hosts light up on a radar view - Port scan — check which ports are open on a host - Wi-Fi scan — see nearby access points, channels, and congestion (something iOS can't do) - SNMP (v2c and v3) — GET and WALK a switch or router - DNS lookup — query A, AAAA, CNAME, MX, and more, over DNS-over-HTTPS or a resolver you pick - SSL/TLS inspector and TLS profiler — check a certificate and how a server negotiates - HTTP inspector — see headers and responses - WHOIS, NTP check, speed test, and more - Subnet calculator — plan and split networks - MAC / OUI lookup — identify a device's vendor from its MAC address, using the full IEEE table on-device Deputy AI and Posse AI: bring your own API key (Anthropic, OpenAI, Gemini, or a local model) and get plain-language help reading a tool's output or a whole set of findings. You pick the model, and you decide when anything goes to it. Private by design: - No telemetry and no ads — the app doesn't phone home - You decide when data leaves your device. The AI features only run with a key you add, to the provider you choose - Demo mode fills every screen with realistic sample data and makes zero network calls of any kind — great for learning the app or taking screenshots without touching your real network Built by a working network engineer. Free, and no account required. AISMITH PDX LLC - Oregon, USA
