Random Port Generator

Made for the task at hand.

Choose candidate ports for local services and test configuration without predictable sequences. Set an inclusive range and generate unique values with Web Crypto. A generated number is only a suggestion; the tool does not bind sockets or claim that a port is currently unused.

How to use

1. Set an inclusive range inside 1024–65535.
2. Choose how many unique ports to generate.
3. Copy the list and check actual availability in your environment.
