What It Does
DCSpeed runs the same real speed test engine as dcspeedtest.com, packaged as a Chrome side-panel extension you can open in one click without leaving your current tab. It measures download, upload, ping, jitter, and bufferbloat (latency under load), and includes an active-tab load-time analyzer and a public IP/ISP detector.
Free vs Pro
The extension is free to install and includes one free speed test per day. DCSpeed Pro removes the daily cap and unlocks the full toolkit:
- Unlimited speed tests, no daily cap
- Bufferbloat / gaming latency-under-load test
- Full test history with CSV export
- Active tab load-time analyzer
- Works on every Chrome you sign into with your email

VPN Comparison Hub
The extension also includes a built-in comparison of NordVPN, ExpressVPN, Surfshark, and Proton VPN — useful for bypassing ISP throttling or lowering gaming latency, with the same honest, no-fabricated-numbers approach used throughout this site.
Permissions & Privacy
DCSpeed requests only the browser permissions it actually uses: tabs (for the active-tab analyzer), storage (to save your local test history), alarms, downloads, and side panel display. It connects to Cloudflare's speed test network, a public IP lookup service, and dcspeedtest.com — nothing else.
