BRev Ping / latency test
Latency & jitter test — in your browser
Measure the round-trip time from your device to the nearest Cloudflare edge, a real API, Google DNS, or a server of your own — with live sparklines, median, jitter and loss. Browsers can't send real ICMP ping, so this times small HTTPS requests instead and says so: the first request (connection setup) is shown separately, and each target is labeled with what its number actually means.

This is HTTPS round-trip time, not ICMP ping. Browsers cannot send real ping packets, so each sample times a tiny HTTPS request with
performance.now(). The first request also pays DNS + TCP + TLS connection setup — it is shown separately as a warm-up and excluded from the stats; later samples ride the warm connection, which is close to (but never below) true network latency.Targets

What this latency test actually measures
Ping vs HTTPS round-tripA classic ping sends ICMP packets, which web pages are not allowed to do. This test times small HTTPS requests instead: slightly higher than ICMP (HTTP adds a little work per request), but measured on a warm connection it tracks real latency closely — and it reflects what web apps actually experience.
Bandwidth ≠ latencyA speed test measures how much data per second; this measures how long one round trip takes. A 1 Gbps line with 200 ms latency still feels sluggish for calls, gaming and typing — you cannot buy your way out of distance and queueing with more bandwidth.
What jitter meansJitter is how much latency varies sample to sample. Video calls and games buffer for the worstrecent sample, so 40 ms with 2 ms jitter feels better than 25 ms with 30 ms jitter. High jitter usually means a congested link or busy Wi-Fi, and it is what makes voices robotic.
Your first hop often dominatesOn many home networks most of the latency (and nearly all the jitter) is the Wi-Fi hop to your router — interference, distance, a microwave running. If numbers look bad, re-test next to the router or on a cable before blaming your provider.
CGNAT and VPNsA VPN adds a detour through its server, so every round trip pays that path twice a leg. Carrier-grade NAT (common on mobile and some fibre ISPs) adds translation hops that can raise latency and jitter. Compare with the VPN off to see what it costs you.
Each target is a different questionThe Cloudflare edge number is "you → the nearest Cloudflare data centre" — close to your best case, not "your internet". The ipify and Google numbers cross more of the internet. Your custom target answers the only question that matters for your own server: how far is it from this chair?
Requests go straight from your browser to the targets you pick (Cloudflare / ipify / Google / your own URL) — BRev has no server in the flow and never sees your results.
