About About
SpeedTesters is a free, privacy-friendly internet speed test that runs in your browser. We measure download, upload, ping, and jitter using Cloudflare’s global network so you can check WiFi, broadband, fiber, cable, and mobile connections without installing an app.
Our goal is clear, actionable results — not a download wall or account requirement. Read the methodology page for how measurements work, and the Privacy Policy for cookies and advertising disclosures.
