About
This site uses cutting-edge WebRTC technology to check your Internet connection's packet loss, latency, and latency jitter in your browser for free. These problems can all be caused by various similar issues, which hopefully you will be able to find and fix using this easy way to test for them.
This complements a traditional speed test, which only measures the raw speed and latency. Speed is important for general Internet browsing, downloading files, and video streaming, but it is not a very good measure for performance for more communicative activities.
Activities like gaming and voice chat usually do not need much raw bandwidth, but they need prompt and reliable responses. These programs also do not usually resend information if it fails to get there, so if packets get lost in transmission, they are gone for good, which can also have a significant impact.
Up until recently, web browsers have not been able to test this, as they have always retried everything until it works. Recently however, WebRTC has been added to modern browsers, finally enabling this type of test. I could not find another site that has implemented this type of test, so I made one. This makes it very easy for anyone to test their packet loss (also known as "packet drop") without downloading a more complicated tool like iPerf. Now, you can just hit "Start Test" below, and then interpret your results.
Also, you can read a bit more about the site at the dedicated About and Technology pages.

Outside the US and SRRC, the DJI FPV Drone is restricted to 25mw or 14dbm in the 5.8 ghz band and 100mw or 20dbm in the 2.4 band.
Our software sends an unlock code to your DJI FPV Drone which unlocks the full 31.5 dbm 1412mw in 5.8ghz & 2.4ghz bands.
The NASA James Webb Space Telescope, developed in partnership with ESA and CSA, is operated by AURA’s Space Telescope Science Institute.
Webb's Science Mission Begins
We wonder. It’s our nature. How did we get here?
Are we alone in the universe?
How does the universe work?
The James Webb Space Telescope is an ambitious scientific endeavor to answer these questions. Webb builds on the legacy of previous space-based telescopes to push the boundaries of human knowledge even further, to the formation of the first galaxies and the horizons of other worlds.
Explore the universe with Webb.
