Internet Speed Test
Measure download speed, upload speed, latency and jitter from your browser using Cloudflare edge network measurements.
Speed measurements run against Cloudflare edge infrastructure instead of the 0bps shared-hosting server. Wi-Fi, VPNs, browser load, device limits and route conditions can still affect the result.
How this test works
0bps uses Cloudflare's open-source browser speed-test engine and Cloudflare edge measurement endpoints. The engine ramps through progressively larger transfers so fast connections are measured over enough data instead of a tiny fixed payload. Packet-loss testing is not enabled in this version.
Privacy note: Running this test sends measurement traffic to Cloudflare. Cloudflare states that completed measurement results are collected for aggregated internet-quality insights. See our Privacy Policy.
What is a good result?
Higher download and upload speeds are generally better. Lower latency and lower jitter are better for gaming, video calls and other real-time applications.
