mDNSShark vs NetDebug Toolkit

mDNSShark is an open-source iPhone app that shows what is on your local network. It uses Multicast DNS (mDNS), DNS-SD, and SSDP to find printers, media servers, IoT gadgets, and other services on your Wi-Fi, with no setup. WHAT YOU GET - Device discovery: Bonjour/mDNS, SSDP, and optional subnet scans, with manufacturer lookups. - Security assessment: flags risky exposed services and checks device manufacturers against CISA's Known Exploited Vulnerabilities catalog and the NVD. - Packet capture: see which hosts your phone talks to (DNS, SNI, ports) and export to pcap for Wireshark. - TLS Inspection (optional subscription): decrypt and read your own device's HTTPS traffic using a certificate you install and trust. PRIVACY Scans and analysis run on your phone. Your device list and scan results are never uploaded. There is no telemetry, no analytics, and no trackers. Two things leave your device, and both are visible to you: DNS lookups go to the resolver you choose (Google Public DNS by default), and the Refresh CISA Data button you tap yourself downloads CISA's public catalog and asks the NVD about device vendors seen on your network. The only permission the app needs is local network access. SUBSCRIPTION TLS Inspection Monthly is an auto-renewing monthly subscription. The price and any free trial are shown in the app before you subscribe. Payment is charged to your Apple Account at confirmation of purchase, or when a free trial ends. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel any time in Settings > Apple Account > Subscriptions. Discovery, scans, and the Security tab are free. OPEN SOURCE mDNSShark is built by engineers who like transparent, lightweight tools, and it is open to anyone curious about local networks.

NetDebug Toolkit is the all-in-one network diagnostics suite for developers, sysadmins, IT teams, and power users. 20 pro-grade tools on iPhone, iPad, and Apple TV. Fast. Focused. No account. No tracking. Diagnose connectivity, DNS, routing, ports, certificates, throughput, and local-network services from one clean interface: NETWORK CORE • Ping : ICMP or HTTP HEAD reachability with timing and packet-loss stats • Traceroute : hop-by-hop route inspection • HTTP(S) Check : status, redirect chain, headers, TLS summary • Speed/Latency Baseline : download/upload presets from 1 MB to 64 MB • iperf3 Client : TCP throughput against an external iperf3 server (upload or download) • Public IP + Geo / ASN / ISP : current WAN IP with carrier and location detail • Path MTU Discovery : largest packet a route carries, black-hole detection, the constricting hop, and safe inner MTU for VPN DNS & DOMAIN • DNS Lookup : forward (host to A/AAAA) and Reverse DNS (IP to PTR), auto-detected from input • DNS Record Explorer : A, AAAA, CNAME, MX, TXT, NS, SRV via DNS-over-HTTPS (custom resolver supported) • Whois : RDAP or IANA WHOIS mode, with chained referrals SECURITY & TLS • TLS Certificate Inspector : full chain, validity, SANs, signature algorithm, weak-cert signals • Subnet Calculator : IPv4 and IPv6, usable host range, broadcast, gateway hints PORTS & CONNECTIVITY • Port Scan : custom ports or ranges • TCP/UDP Connect : per-port reachability with built-in UDP profiles (DNS, NTP, SNMP, SIP, RADIUS, TFTP, memcached) • NTP Time Check : clock offset vs. any NTP server with delay, stratum, and leap details • External Port Check : "can the internet reach me?" 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.
