SpeedPulse

SpeedPulse is a free internet speed test that measures more than raw Mbps. Alongside download and upload speed, it measures idle latency, jitter, and bufferbloat — how much your latency grows when the line is busy, the #1 hidden cause of stuttering calls and laggy games. After every test it probes 8 independent CDN edges to show whether your ISP treats speed-test traffic specially, and translates your numbers into plain-English verdicts for streaming, gaming, video calls and browsing. Includes connection info, unit switching, CSV export, shareable result cards and a local history trend chart. No signup, no cookies.
