0–1% loss
Ideal to acceptable
Real-time apps should generally feel stable when latency and jitter are also low.
Free Packet Loss Test Online
A packet loss test checks whether network requests reach their destination reliably. Run this free browser test to measure application-layer loss, round-trip latency, and jitter, then see what the results mean for gaming, video calls, and streaming.

What this measures: small same-origin HTTP round trips. Browser security prevents raw ICMP or UDP testing, so use this result as a practical application-layer signal, not a replacement for router or ISP diagnostics.

Live metrics update after every probe.

Calls or games may stutter. Compare Wi-Fi with Ethernet and repeat the test.

Expect interruptions in real-time traffic. Check your local network and contact your ISP if it persists.
Packet loss test FAQ
What is packet loss?
Packet loss happens when some data sent across a network never reaches its destination. It can cause lag, frozen video, robotic audio, buffering, and disconnected sessions.
How does this browser packet loss test work?
It sends small, uncached HTTP requests to NitroClaw and measures which requests return before the timeout. Browsers cannot send raw ICMP packets, so this is an application-layer approximation rather than an ICMP ping test.
What is a good packet loss percentage?
Zero percent is ideal. Up to 1% may be acceptable for many uses, while sustained loss above 3% often causes noticeable problems in games and real-time calls.
What is network jitter?
Jitter is the variation between consecutive response times. Lower jitter means data arrives consistently, which matters for calls, streaming, and online games.
How can I reduce packet loss?
Try Ethernet, move closer to the router, pause large uploads, restart network equipment, update router firmware, and compare another device. Persistent loss may require help from your ISP.
