NetDiag+
Latency Dashboard
Pings the game regions, CDN edges and carriers people in your country actually use, sorted worst first. Your router is checked before any of them, so nothing blames a server when the fault is at home.
Your network, explained
Video calls freezing? VPN refusing to connect? Games dropping packets? NetDiag+ explains what is actually happening and which link is at fault — with the 31 tools a network engineer would reach for, on the phone in your pocket.

Bufferbloat test
Loads the line on purpose and pings your router and the internet at the same time, then grades it A to F and names who is queueing your packets: your Wi-Fi, your router, or your ISP.
MTR & traceroute
See the full path your traffic takes and exactly which hop starts losing packets.
Path MTU discovery
Find the largest packet your connection can carry end-to-end — one clear number to put in your router.
TLS & certificates
Inspect the certificate chain, expiry dates and the negotiated cipher suite.
Encrypted DNS
Test DoH and DoT resolvers, compare them, and see which one answers fastest.
Built for the moment something breaks
Every tool runs on raw BSD sockets — no jailbreak, no root, no waiting for a desktop. Every result can be exported as plain text, which is what turns a diagnosis into evidence when you open a ticket with your provider.
What users are saying
“The interface is clean, smooth, and very intuitive. I was especially impressed by the flawless Arabic and RTL support — it’s rare to see a developer pay such close attention to detail for Arabic users.”
