SpeedOf.Me is an internet speed test service which uses browser capabilities such as HTML5 and JavaScript to measure a user's internet connection speed. SpeedOf.Me utilizes multiple servers around the world, with the server used being chosen automatically based on location. It is financed through its paid API as well as advertising.
Features SpeedOf.Me reports download and upload throughput, latency (ping) and jitter, and runs in the web browser without a plug-in or app. Rather than transferring data all at once, it downloads and uploads a series of progressively larger sample files in sequence, an approach the service says approximates real-world web browsing. Results can be saved to a local history and shared as an image link.
API and integrations The service provides a JavaScript-based API that lets third-party websites and applications embed its speed test without operating their own test servers, with example integrations for frameworks including React, Vue, Angular, Electron, Flutter, iOS and Android. In January 2026 it published , a Node.js package that bundles a command-line tool, a programmatic SDK and a Model Context Protocol (MCP) server, the last of which lets AI agents run speed tests on a user's behalf.
