Best Speed Test Websites for Chromebook

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!
