The test runs in your browser against Cloudflare’s measurement service. Cloudflare receives the measurement data; we do not store your result.
A browser test measures the path from this browser to Cloudflare’s nearest measurement edge, not the speed of any operator or plan.
How this works and its limits
The live test runs in your browser and measures download, upload and latency against Cloudflare’s nearest measurement edge. It starts only when you press the button.
The result appears here and is not stored by us. Cloudflare receives the measurement data as the test runs; the disclosure sits next to the button.
Data sources and licences
Operator names, brands and codes shown here are public reference data compiled from national regulators and other public sources.

The browser speed test uses Cloudflare's open-source measurement engine, Copyright (c) 2023 Cloudflare, licensed under the MIT License (opens in a new tab).

What a browser speed test measures, and what it does not
A browser speed test sends and receives data between this browser and a nearby measurement service. The download figure is how fast data arrived, the upload figure how fast it left, and latency is the round-trip time of a small request. The test also reports latency while the connection is busy, which is often closer to what video calls and games feel.
The test measures the path from this browser to Cloudflare’s nearest edge. That path includes your access network, your device, Wi-Fi and the route to the edge. It is not the speed of any operator or plan, and a result on one device or network says nothing about another.
