A free internet speed testing and network diagnostic tool.
WiFiSpeedTest is a free, browser-based tool for measuring HTTP download throughput, upload throughput, round-trip time, and jitter between a browser and this site's Cloudflare endpoints. It requires JavaScript and the web APIs used by the selected feature.
Measure how fast you can receive data from the internet.
Measure how fast you can send data to the internet.
Measure HTTP round-trip time and variation between consecutive successful samples.
Public-IP context, egress consistency, browser network diagnostics, public-host port checks, route overview, and saved-test comparisons.
WiFiSpeedTest transfers generated data between your browser and Cloudflare-hosted endpoints. The current implementation:
Saved history stays in that browser's local storage. Infrastructure, analytics, and advertising data flows are described in the Privacy Policy.
The current tools do not require payment or an account. Adsterra advertisements support site operation.
Results describe the tested browser, device, route, and Cloudflare edge during that run. Other traffic, device load, radio conditions, request scheduling, and route changes can change the result. Repeat measurements under documented conditions and compare like with like. See the measurement method and limitations.
The front end uses HTML, CSS, and JavaScript. Static pages are hosted on Cloudflare Pages and measurement endpoints run as Cloudflare Pages Functions.
