Limitations
This tool runs entirely in your browser. It attempts to connect to ports using WebSockets or Image loading tricks. It is not as accurate as a server-side scanner like Nmap, but it works well for checking web servers and common services.
Note: Some firewalls may block these requests or show them as "Closed" even if they are open.
