About WiFi Speed Insight
A fast, honest WiFi toolkit that works on any device, with no app and no account.
What we do
WiFi Speed Insight started from a simple idea: the WiFi tools people install on their phones should also work in a browser. So we built a WiFi speed test and a set of network tools that run on any phone, tablet or computer, plus guides that explain the results in plain English.
How the measurements work
Speed and latency tests run against Cloudflare’s global speed-test servers, so you’re usually measured against a server in or near your own city. Download and upload use several parallel connections and ignore the first quarter of each test (the warm-up), which matches how most modern speed tests work. Ping is timed with small HTTPS requests because browsers can’t send traditional ICMP pings.
If the test server can’t be reached, for example because a firewall blocks it, WiFi Speed Insight shows a clearly labelled demo run instead of inventing a result.
What a website can’t see
Browsers deliberately hide your WiFi network name, signal strength, saved passwords and the devices on your network. We don’t pretend otherwise. Instead, our guides show you where to find those details on iPhone, Android and your router.
Privacy first
The QR code and password tools run entirely on your device. Test history is stored only in your browser. There are no accounts and no tracking cookies. The details are in our privacy policy and terms of use.
