Description

GrandSpeed surpasses conventional speed testing tools that typically assess only upload and download speeds. In addition to these metrics, it evaluates idle and loaded latency (while simultaneous activities occur), jitter, packet loss, and bufferbloat. Remarkably, GrandSpeed also identifies the highest video resolution achievable for streaming services like Netflix and the optimal resolution for live streaming through your internet connection. Furthermore, it automatically assesses the fitness of your connection for gaming and audio/video calls or conferences, taking into account upload speeds, latencies, and packet loss. The tool also calculates the amount of data you can download within an hour and over a full day, which is beneficial for planning large file downloads. Additionally, it features a Speed Budget calculator that assists in determining the minimum internet service level you should consider, based on the number of devices connected to your network. This comprehensive evaluation makes GrandSpeed an invaluable resource for optimizing your internet experience.

Description

SpeedOf.Me has measured internet speed in the browser since December 2011, when it shipped as the first HTML5 speed test. It reports download, upload, latency and jitter and plots them live as the test runs, with no app, plugin or download, on desktops, phones, tablets, game consoles, smart TVs and cars. The method is deliberate: one stream, from the browser, to neutral third-party CDN edge servers in more than 130 locations, over the same open-internet path your browsing and video already take. Tests that hit a server inside your own provider's network with many parallel streams report a best-case peak instead. That number is called Real-World Speed, and because the method has not changed since 2011 the figures stay comparable year over year. Developers can run the same engine themselves. Drop in api.js, set an account key and domain, call SomApi.startTest(), and results return through callbacks, white-labelled, with nothing to host. Examples ship for vanilla JavaScript, React, Vue, Angular, React Native, Electron, Flutter, iOS, macOS, Android and Windows, and the portal reports calls, geography, device mix and speed trends. AI agents get the same access through @speedofme/mcp, one npm package that is a Model Context Protocol server, a CLI and a Node SDK, working with Claude, Cursor, Windsurf, Zed, VS Code, Cline, Continue, JetBrains and Goose. The Internet Speed Atlas aggregates millions of anonymised tests into real-world figures for 119 countries.
