Enter Target Host.
Type any domain name (e.g. github.com) or IP address. Use the quick presets for common targets or test your own server directly.

Send ICMP-style HTTP probes to any domain or IP address and measure real-time round-trip latency — right from your browser.
NOTE: Browser security prevents raw ICMP. This tool uses HTTP HEAD requests to measure round-trip time — functionally equivalent for connectivity testing.

"Every network problem starts with knowing if the host is reachable."
Browsers cannot send raw ICMP packets. This tool fires HTTP HEAD requests to the target — the fastest possible HTTP method — and measures the precise round-trip time using the performance.now() API.
"Precision measurement at the application layer — no plugins, no installs."
Each response is logged with sequence number, bytes, TTL estimate, and latency category — fast (<50ms), moderate (50–150ms), or slow (>150ms). Packet loss, min, max, and average are calculated live.
"Data in real-time. Decisions in seconds."
Traceroute, DNS Lookup, Port Scanner, SSL Checker — and more tools are being added to this suite. Or let's build something specific for your infrastructure.
