Signalyzr — Why is my internet slow? Find out in 30 seconds.

Signalyzr (pronounced "signal-eye-zer", short for "signal analyzer") is a free network diagnostic tool made in India. We tell you exactly why your internet is slow — whether the problem is your Wi-Fi, your router, your phone, or your ISP (Jio, Airtel, Vi, BSNL, ACT Fibernet, Hathway, Excitel, Tata Play) — and what to actually fix.

Signalyzr is a consumer network diagnostics tool — not the same as Microsoft SignalR (an ASP.NET framework) or the Python "signalyzer" package (a signal-processing library). We just have unfortunately similar names.

What Signalyzr measures, free, with no signup:

• Real download & upload speed (sustained, not just peak)
• Latency and jitter — the actual numbers that decide video-call quality
• Packet loss — the main reason calls freeze and games lag
• DNS lookup time — often the real cause of "slow" browsing
• Carrier and ISP identification — Jio, Airtel, Vi, BSNL, ACT, Hathway, etc.
• Root-cause diagnosis in plain language
• Step-by-step fix recommendations specific to your problem
