Best Speed Test Websites for Linux

SpeedOf.Me is a free, browser-based internet speed test that measures download, upload, latency and jitter on any device: desktop, mobile, tablet, game console, smart TV or car. No app, no plugin, no download. Launched in 2011 as the first HTML5 speed test, it runs a single stream from your browser to neutral CDN edge servers in 130+ locations, so the result reflects real browsing performance instead of a lab-style peak. We call it Real-World Speed. Developers can embed the same engine with the SpeedOf.Me API: a few lines of JavaScript, white-label, with callbacks for every metric and an analytics dashboard for usage, geography and devices. Ready-to-run examples cover React, Vue, Angular, Electron, Flutter, iOS, Android and more. An MCP server and CLI (@speedofme/mcp) let AI agents and CI pipelines run real speed tests. The Internet Speed Atlas publishes real-world averages for 119 countries.

The website speed test from Dotcom-Tools enables users to test their web pages from for free with up to three worldwide locations, including from behind the Great Firewall of China to ensure your website can be accessed from users within China. Once a test is complete, users can drill into robust performance reports and waterfall chart analysis. Users may also select which browser they'd like to test from. This test supports Chrome, Edge and mobile browsers including Android, iPhone, iPad and more!

Designed to replicate your real-world connection speed! We are using the latest technology available to test your Bandwidth. This application is designed for testing any connection, from 1 Kbps to 1 Gbps+. Our algorithm automatically detects your stable download and upload speed from our servers. We use HTML5! And no flash or Java is used, so you also get a better understanding of your web browser too. The connection speed in between you and the connected server. Final result will be the average value of the fastest download/Upload burst rates during the Bandwidth. Your test results may vary at different times of the day due to network congestion, and the web browser you choose etc. To get a good understanding of your bandwidth run the test at different times of the day. An application for launching a quick speed test server, without using any commands! This application can run offline! So you can use it to test your Local Area Network/WiFi or put it on a server to test your speed.
