About Kencang

Kencang provides fast, accurate internet speed testing for everyone. Our mission is to help users understand their internet connection quality through reliable, unbiased testing.

Our Mission

We believe everyone deserves to know their true internet speed. ISPs advertise speeds, but real-world performance often differs. Kencang gives you the tools to verify your connection and make informed decisions about your internet service.

Our speed test is free, requires no registration, and works on any device with a modern web browser. We do not serve ads that interfere with test accuracy, and we do not sell your data.

The Technology

Kencang uses the NDT7 protocol (Network Diagnostic Tool version 7), developed by Measurement Lab (M-Lab). NDT7 is an open-source protocol designed for accurate, reproducible internet performance measurements.

Key advantages of NDT7:

  • Accuracy - Uses WebSocket for efficient, modern measurements
  • Transparency - Open-source protocol with public methodology
  • Research-Grade - Developed by internet researchers for scientific accuracy
  • No Inflation - Measures actual throughput without artificial boosting
