Which tool should I use?
| What's happening | Start with |
|---|---|
| Nothing loads, or one site or app won't open | Is My Internet Down? |
| Games lag or pages feel slow to start | Ping Test |
| Video calls freeze or audio goes robotic | Jitter Test |
| WiFi keeps disconnecting | WiFi Drop Test |
| Problems come and go, or you need proof for your ISP | 24/7 Monitor |
How these tools measure your connection
Browsers can't send the raw "ping" packets a command line uses, so every tool here measures the same way our 24/7 monitor does: it sends tiny DNS-over-HTTPS requests to Google's public DNS service (8.8.8.8), with Cloudflare's 1.1.1.1 as a fallback, and times how long each round trip takes. That's a real request over your real connection, so it reflects what your apps and browser actually experience. Results are typically a few milliseconds higher than a command-line ping to the same server.
Nothing is installed and nothing about you is sent to us. The requests go straight from your browser to Google or Cloudflare, and results stay on your device unless you choose to share them. Each tool explains its own limits on its page: for example, why browser tests report failed requests instead of true packet loss, and why some websites can't be checked from a browser.
Snapshots vs monitoring
The quick tests answer "what is my connection doing right now?" That's often enough: you find out it's your WiFi, or that one website is down, and you fix it. But many connection problems are intermittent. Drops every evening, a router that stalls once an hour, or congestion at peak times will pass a 10-second test and still ruin your next call.
For those, the 24/7 monitor is the right tool. Leave it open in a browser tab and it checks your connection every second, records every outage and slowdown with the time and length, and builds a shareable report. That's the evidence that gets an ISP to take a complaint seriously. Our guide on how to prove your ISP is unreliable shows how to use it.
