Troubleshoot Wi-Fi issues, inspect DNS records, scan ports, and diagnose connectivity problems, all from your pocket.
Whether you're a network engineer responding to an outage, a developer debugging API connections, or a home-lab enthusiast checking on your NAS, NetDebug Toolkit puts 16 professional-grade networking tools in a single, clean app for iOS and tvOS.
16 Network Tools in One App
Connectivity Tools
- Ping: Test host reachability with ICMP or HTTP HEAD. See per-packet latency, packet loss, and round-trip statistics. When ICMP is blocked by a firewall, switch to HTTP HEAD with one tap.
- HTTP(S) Check: Verify URL reachability, view status codes, response timing, redirect chains, and a quick TLS summary.
- Traceroute: Visualize the hop-by-hop path your traffic takes to any destination. Identify where latency spikes or packet loss occurs.
- Speed & Latency Baseline: Get a quick snapshot of latency, jitter, and download/upload throughput on your current connection.
- TCP/UDP Connect: Test whether a specific host and port combination is reachable, with connection timing and clear error reasons.
- Wake-on-LAN Sender: Send magic packets to power on compatible devices across your local network.
Lookup Tools
- WHOIS: Look up domain registration details, registrar info, nameservers, and lifecycle events using RDAP (with automatic WHOIS fallback).
- DNS Lookup: Resolve hostnames using system or custom DNS servers.
- DNS Record Explorer: Query A, AAAA, CNAME, MX, TXT, NS, and SRV records with full TTL display.
- TLS Certificate Inspector: Examine certificate expiry dates, Subject Alternative Names (SANs), the full issuer chain, and weak-certificate signals.
- Public IP + Geo/ASN: Instantly see your public IP address, ISP, ASN, and approximate geolocation.
Scanning Tools
- Port Scan: Check TCP port reachability across custom port ranges.
- LAN Scan: Sweep your local subnet to discover active hosts.
- Subnet Calculator: Compute CIDR details, usable host ranges, broadcast addresses, and gateway suggestions for both IPv4 and IPv6.
- Bonjour Browser: Discover .local network services like AirPlay, HomeKit, printers, and more using mDNS.
- UPnP / NAT-PMP Discovery: Detect local gateway mapping support and external IP hints.
Save Hosts and Work Faster
NetDebug Toolkit isn't just a collection of one-off tools. Its Saved Hosts feature lets you store domains, IP addresses, and MAC addresses that you frequently diagnose. Select a saved host, and every relevant tool is pre-filled and ready to run.
- Save hosts by domain/IP or MAC address
- Add optional display names for quick identification
- Automatic duplicate prevention
- Host-scoped tool lists that filter based on host type (MAC address hosts automatically surface Wake-on-LAN)
