Why Install DCSpeed for Chrome?
Traditional browser tests require switching tabs, waiting through heavy ad reloads, and re-testing manually. DCSpeed embeds directly into the Chrome Side Panel API, measuring your true line capacity on Cloudflare edge endpoints with sub-millisecond precision.
Chrome Side Panel
Test live connection speeds without ever closing or leaving your active Zoom call, game queue, or work document.
Bufferbloat & Jitter
Measures latency under heavy upload/download loads to diagnose lag spikes in Valorant, CS2, Fortnite, and Discord voice calls.
Active Tab Load Profiler
Deep-dive into page DOM render times, DNS handshake latency, and TTFB for any website you are currently browsing.
