About Internet Speed Test

⚡ Download Speed

Downloads test files from Cloudflare CDN endpoints. Measures throughput in Mbps by timing multiple parallel downloads.

📡 Latency & Jitter

Latency: average round-trip time to CDN. Jitter: variation in latency. Lower = more stable connection for gaming/voip.

🌐 CDN-Based

Uses fetch API against CDN endpoints that are geographically distributed. Tests real-world browsing performance.

🔒 Browser-Only

No upload speed test (requires server). Download-only measurement. All tests run from your browser via standard fetch.
