What services use port 3001?

Port 3001 is commonly used by various applications and services, particularly in development environments. Some typical uses include:

1. Node.js Applications: Many developers use port 3001 for local development of Node.js applications, especially when running web servers or APIs.
2. React Development Server: The default port for the development server when using Create React App can be 3000 or 3001, depending on the configuration.
3. WebSocket Services: Some WebSocket applications may use port 3001 for real-time communication.

While these are common uses, it's essential to verify what specific service is running on your system on that port. You can use tools like Nmap or netstat to check which service is listening on port 3001.
