Port Checker
Check if specific network ports are open on a host. Scan common service ports.
Important Notice
This tool attempts WebSocket connections to check port status. Due to browser security restrictions, results may be limited. The target host will see connection attempts from your IP address. Only scan hosts you own or have permission to test.
Port Scanner
Enter a hostname and ports to scan. Use commas or ranges (e.g., 80,443 or 20-25).
Port Status Meanings:
Open: Service is accepting connections • Closed: Port is reachable but no service • Filtered: Blocked by firewall or no response
