Network Latency Intelligence

Every millisecond,
accounted for.

PINGCHECK streams continuous round-trips between your device and the server and dissects each one - DNS lookup, TCP handshake, TLS negotiation, time-to-first-byte and payload transfer - with transport detection for TCP and UDP/QUIC. Stop it whenever you like and get a forensic-grade report.
