Why it exists
Headline speed is only part of the experience.
Broadband packages are normally promoted using download speeds, but day-to-day performance also depends on upload capacity, latency, jitter, Wi-Fi coverage, device capability and how many people are sharing the connection.
Speedly was created to put those measurements in one clean interface and explain them in plain English. The aim is not to promise laboratory-grade results from a web browser; it is to provide a useful, repeatable indication of how a connection performs from the device being tested.
What Speedly measures
The speed test measures download throughput, upload throughput, round-trip latency and latency variation. Results can change according to your device, browser, connection type, Wi-Fi conditions, server route, congestion and other network activity.
A practical approach
We encourage users to compare several tests rather than relying on a single number. A wired baseline can help identify whether a problem is with the broadband connection itself or the local Wi-Fi network.
