Katnet vs NetScope

katnet is a network discovery and connectivity toolkit for IT Professionals. See which hosts are online, which ports respond, and what each device advertises-then jump straight into SSH or VNC when you need a terminal or remote desktop. Discover devices Run a TCP sweep across your subnet (with a sensible default port set, or your own list). Results merge with Bonjour browsing and SSDP/UPnP-style hints so cameras, printers, NAS boxes, and servers show up with clearer context. Enrichment includes lightweight probes where appropriate (for example HTTP, TLS certificate summaries, SSH banners, and SNMP where reachable) to build a richer fingerprint-without sending your scan results to us. Built-in clients Use SSH for shell access and VNC for remote screen sharing to machines you are authorized to manage. A URL test tab helps verify HTTP/HTTPS reachability and status. A Status view summarizes local addressing and network context. Privacy katnet is built for on-network, on-device use. Discovery talks to your routers, printers, and servers over local Wi-Fi or Ethernet. You control when scanning runs. Grant Local Network access when iOS asks so multicast, Bonjour, and LAN probes can work. Important Only scan networks and systems you own or have explicit permission to test. Unauthorized scanning or access may violate law or policy.

"The internet is bad today" is almost never about your internet. It is usually one of four things, and NetScope tells you which one. ONE SCORE, WITH REASONS Tap once and NetScope runs the full check, then gives you a number out of 100 and a plain-English list of what it found. Not graphs you have to interpret — sentences like "the delay keeps changing, which is what makes calls break up". IT SEPARATES YOUR WI-FI FROM YOUR LINE NetScope times your router separately from the internet beyond it. If the router answers slowly, the weak part is the Wi-Fi hop in your own home — moving closer or changing channel will help. If the router is fast and the internet is slow, the problem is upstream and no amount of rearranging furniture will fix it. WHAT IT MEASURES • Latency, sampled repeatedly, plus the jitter between samples — jitter is what actually breaks up a call • Packet loss • Your router's own response time • DNS lookup times, the most common fixable cause of a fast line that feels slow • Download and upload throughput SEE WHAT ELSE IS ON YOUR NETWORK NetScope knocks on every address in your subnet and listens for anything announcing itself over Bonjour, then names what it finds: routers, printers, speakers, TVs, computers, other phones. INDIVIDUAL TOOLS Latency, DNS and speed are all runnable on their own, against any host you type in. PRIVACY Latency, DNS and device scanning all run from your iPhone and nothing is stored or transmitted. The one exception is the speed test, which uses Cloudflare's public speed endpoint — and only when you ask for it. NetScope only ever scans the network your iPhone is already on.
