Scan ports on your local machine to detect running services, Docker containers, and development servers. This tool uses browser-based HTTP requests (with CORS and no-cors modes) and WebSocket connections to detect open ports and gather information about running services. Due to browser security restrictions, some services may show limited details (CORS blocked), and only HTTP/HTTPS/WebSocket protocols can be reliably detected.
Scan commonly used development and service ports
Scan a custom range of ports (maximum 10000 ports per scan)
Scan specific ports (comma-separated, e.g., 80,443,3000,8080)
