What is tcping?

Tcping is a command-line tool that checks whether a specific service or website is reachable and measures how long it takes to connect. It works like the traditional "ping" utility that network administrators use, but instead of just checking whether a server is turned on, it checks whether a particular port or web endpoint on that server is actually responding. By default, it sends four connection attempts and reports the timing for each, then gives you a summary with the minimum, maximum, and average response times. The tool operates in two modes. In plain TCP mode, you give it a domain name and a port number, and it tries to open a connection to that port, reporting how many milliseconds the connection took. In HTTP mode (triggered with a flag), it actually sends a web request and reports not just the connection time but also the HTTP status code returned and the size of the response in bytes. This gives you a quick picture of whether a website is up and how fast it's responding. This would be useful for anyone who needs to monitor or troubleshoot network services. For example, if you run a web app and want to verify that your server is accepting connections on port 443 (the standard HTTPS port), you can point the tool at your domain and get an immediate answer. It's also handy for checking whether a database or API endpoint is reachable before digging into deeper debugging. System administrators, developers debugging connectivity issues, or anyone managing infrastructure would find it practical. The project is written in Go, which means it compiles to a single standalone file you can run on any operating system without installing additional dependencies. The README doesn't go into much detail beyond the basic usage examples, so if you need more advanced features, you'd need to explore the code itself.
