After finally getting frustrated enough with having to juggle multiple different tools needed to diagnose network and IT issues, I (with a little [alot] of help from Claude) put together a desktop app that pulls them all into a single centralised place.
Here's a quick rundown of what tools the app actually includes, from my co-dev, Claude himself:
Path analysis — MTR-style traceroute with real-time per-hop packet loss and latency, not just a one-shot tracert
LAN scanning — subnet sweep, DHCP probing, mDNS/SSDP discovery and WiFi channel analysis
Switch discovery — CDP/LLDP neighbour detection with port logging, so you can see actual topology not just ARP tables
Diagnostics — DNS lookups + propagation checking, port scanning, SSL/TLS cert inspection, WHOIS/RDAP, ping, Wake-on-LAN
IP tools — subnet calculator, VLSM planner, MAC/OUI lookup, BGP/ASN inspection
Devices — SNMP browser, TFTP server, syslog receiver
SSH/serial terminal with an AES-GCM encrypted credential vault
Speed test benchmarked against M-Lab medians
As you can see, its a nice collection of tools I and the guys i've worked with use from time to time, all in one place, completely free to use, no account needed, and runs completely offline on your machine for the most part (obviously excluding the tools that need internet access such as the Speed Test, Ping).
Its backend is built with Tauri and Rust, with TypeScript for the frontend. Works across Windows, MacOS and Linux too.
If you'd like to give it a whirl you can check it out here; https://www.purple.ai/network-multi-tool, if you've got questions or have any feedback on if this is something that is actually useful, saves you a headache, anything missing or what you'd just find cool to see included please let me know! >B^)
