Advanced Port Scanner vs Port Authority

Advanced Port Scanner is a free Windows desktop utility for finding open network ports and identifying software versions reachable through them. It scans TCP and UDP ports across an IP address range and lets you specify which ports to check. Multi-threaded scanning is available, while a high-accuracy mode checks each computer repeatedly at a slower pace. For LAN administration, the program provides Wake-On-LAN, remote shutdown, and commands that can run on remote computers. Discovered systems can be opened through HTTP, HTTPS, FTP, Telnet, SSH, RDP, or Radmin, with configurable clients for some protocols. Computer lists can be exported to XML, HTML, or CSV, and favorites can be loaded from XML. Radmin connections require Radmin Viewer. Famatech describes the tool for LAN and networking work, and says shutdown actions require authorization. It is distributed as a Windows executable installer and costs nothing.

Port Authority is a free Android port scanner for discovering network hosts and viewing network information. It discovers LAN hosts and public IP addresses, then scans TCP ports on LAN and WAN hosts with custom ranges. Network tools include MAC-address vendor detection, DNS record lookups, and Wake-on-LAN for local hosts. Lightweight SSH and HTTP(S) fingerprinting identifies server type and version. The maker describes host discovery as typically taking less than five seconds and scans as heavily threaded. The app says it has no ads or analytics trackers and does not track, collect, or share data. It requires limited permissions for network interaction. Public IP detection uses the maker’s open-source stateless service. The free app is GPL-3.0 licensed; a 4.99 USD once donation plan has the same features.
