TCP port-forwarding test from an outside server (open/closed/filtered) • Run History & Trends : every run is saved on-device with charts of latency, speed, and more over time (free; longer retention with a purchase) LOCAL NETWORK • LAN Scan : fast or deep subnet host discovery • mDNS / Bonjour Browser : AirPlay, HomeKit, Matter, printers, SMB, SSH, and more • UPnP / NAT-PMP Discovery : router gateway port-mapping introspection • Wake-on-LAN Sender : send magic packets to wake compatible devices POWER-USER WORKFLOW • Saved Hosts : store frequently used IPs, hostnames, and MAC addresses with per-host tool defaults • My Automation : chain multiple tools into one-tap workflows with a combined PDF, PNG, or text run report • Export & Import : portable JSON files for automations and saved hosts (iOS share sheet, tvOS QR-code download) • Universal Links & Deeplinks : open any tool from a URL with pre-filled inputs, auto-run, and auto-export, e.g. https://netdebug.developerinsider.co/open/ping?target=1.1.1.1&export=pdf • Copy Deeplink : every tool and saved automation can copy its own shareable Universal Link • Built-in tool docs : quick-reference markdown for every tool APPLE TV / tvOS • Full feature parity : every tool, Saved Hosts, My Automation, and all three in-app purchases ship on Apple TV • LAN-only QR-code export : Apple TV serves run reports and JSON exports over a one-shot HTTP server; scan the QR with your phone to download LOCALIZED IN 21 LANGUAGES English, Arabic, Bengali, Chinese (Simplified), Dutch, French, German, Hindi, Hinglish, Indonesian, Italian, Japanese, Korean, Polish, Portuguese (Brazil), Russian, Spanish, Thai, Turkish, Ukrainian, Vietnamese.
