CLI tool that pings any TCP port to measure latency and verify connection reliability without raw sockets.

Desktopfreeglobal

tcpie is a free, open-source command-line tool that measures TCP port latency and connection reliability using a handshake-then-terminate approach, running fine without raw socket access. It's for network engineers and developers who need to test whether a specific TCP port is reachable, not just ICMP ping.
