About OpenSpeedTest

OpenSpeedTest is an HTML5 internet speed test that runs in a web browser. It measures download speed, upload speed, ping, and jitter between a device and a test server. The homepage says the test needs no app, plugin, Flash, or Java, and it works on phones, tablets, TVs, consoles, and computers. The homepage also describes the test as designed to reflect real-world connection speed and to automatically identify the most stable download and upload speeds during each session.

The site also offers options for hosting the test. Website owners can embed the test as a widget, which uses OpenSpeedTest servers. Network administrators can deploy a self-hosted test server using the source code or a Docker image. The homepage states that results show the average of the fastest download and upload bursts during a test, and that speeds vary with network congestion, WiFi interference, device limitations, and browser differences. The homepage also says the site uses the Cachefly CDN.
