Guide

Random Port Generator

Table of Contents

This tool is a simple, browser-based utility that generates a random, available port number for your applications, servers, and scripts. It’s designed to give you a quick and reliable port to use for development and testing without the risk of conflicting with a well-known port.

How It Works

The tool generates a random integer between 1024 and 65535. This range is chosen specifically to avoid the “well-known ports” (0-1023), which are reserved for common services like HTTP, FTP, and SSH. By using a port outside this range, you can avoid conflicts when you’re running local servers or applications.

Simply click the Refresh button to get a new port number. The generated number is displayed prominently and can be copied to your clipboard with a single click.

Use Cases

  • Local Development: Quickly get a port for running a new web server, API, or database without needing to manually check for open ports.
  • Testing: Use a random port to ensure your application can dynamically bind to any available port, rather than relying on a hardcoded value.
  • Configuration: Generate a new port for a service in a configuration file to prevent conflicts with other applications.
  • Scripting: Integrate the tool into a script to get a random port for a temporary process.
