Network Diagnostics
The network test that shows what Speedtest hides
Network Diagnostics launched on March 17, 2026.
What it does
NetworkTests.com goes beyond traditional speed tests. Tools like Speedtest rely on TCP, which retransmits lost packets and can hide network issues. NetworkTests.com uses WebRTC UDP to measure real packet loss, latency, and jitter experienced by video calls, gaming, and VoIP. It also performs hop-by-hop path diagnostics from server to your connection edge. Includes tools like IP lookup, DNS lookup/trace, traceroute, ping, MTR, VPN detection, DNS leak test, and SSL proxy check.
Free browser-based network diagnostics: ping, traceroute, MTR, DNS lookup, VPN check, ASN lookup, MAC lookup and more. No install required.
NetworkTests measures the things a speed test cannot see. A bandwidth number tells you how much data your line can move; it says nothing about whether packets arrive intact, arrive on time, or arrive at all. Packet loss, latency spikes and jitter are what actually break video calls, voice chat and online games — and they are invisible to a throughput test. The test runs entirely in your browser. Nothing to install, no account required, and it works on Windows, macOS, Linux, Android and iOS. Most online tools test one thing. Running all three in a single pass is what makes a result diagnostic rather than merely descriptive. UDP measurement exposes raw loss and jitter without TCP's…from networktests.com
