Website Port Checker Tools are often employed, as part of a port scanner software, to check for open and closed ports of a network. Ports are entry and exit points for data requests, which are vulnerable to attack from hackers if left unexamined. Port scanners and port checkers allow us to scrutinize the performance and status of these ports, i.e. are they open or closed, how well are they performing, etc.

How does A Website Port Checker work?

Generally, there are two protocols, TCP and UDP, for checking ports. The process comprises of five simple steps, explained as follows:

  • The first thing you need is an active, for scanning a port. You can explore active hosts via network scanning.
  • Each active host is mapped to its unique IP address.
  • The port checker will now perform a scan by sending packets of data through various ports to test whether they are open or closed.
  • The responses of the ports are analyzed.
  • The data is compiled, the threat level is analyzed, port status is determined, and everything is displayed to the user.

Port scanners can connect to a myriad of different hosts and perform several types of scans including a stealth scan (seek the other party’s consent first). If you are looking for an excellent website port checker tool, hang tight and read on to discover our top picks.

5 Website Port Checker Tools

After much comparing, researching, reviewing, and scrutinizing, we have narrowed down our picks to the 5 tools mentioned below:

  • Its multithreaded scanning option allows you to cut down scan times.
  • You can choose a DNS server of your choice.
  • You can use a command-line system if you please (experienced users only).
  • It scans and reveals the status of ports.

Verdict: SolarWinds Port Scanner is the perfect free option for exploring network security vulnerabilities.

5.      NetCat

NetCat acts as both a network debugging and exploration tool. It is a backend software that can use either IP or TCP connection to scan data across a network. The software is ideal for advanced users as it hosts features like buffered send-mode and hexdump.


NetCat has the following salient features:

  • It is compatible with Linux, FreeBSD, Solaris, macOS, and NetBSD (not Windows).
  • Connections, both inbound and outbound, are accessible via all of the ports.
  • It features both TCP and UDP protocols.
  • It has several unique built-in features like tunneling mode, random port scanner, buffered send-mode, and hexdump.

Verdict: NetCat is a decent option for those seeking a more advanced tool for more high-end operations, however, it is not available on Windows.

Our Recommendations

The port checkers mentioned in this list are versatile and varied options. There are a ton of online port checker software on the market, we selected these few because of their unique features. NMap is a decent simplistic option, suited for most users. However, for more advanced-end users, Angry IP Scanner and NetCat are potent choices.

Port Checker Software Are Essential For Your Network

Port checkers are quintessential for exploring network vulnerabilities, maintaining port security, checking for blocked ports, and exerting administrative control over a network. These are the basic requirements for business networks and in some cases, even domestic networks so that they work optimally and safely.
