About this tool

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.

Common questions
Are the ports guaranteed to be available?

No. Availability changes between machines and over time. This generator does not scan or bind ports, so verify with your application or operating system.

Why does the range start at 1024?

Ports below 1024 are well-known and commonly require elevated privileges. This tool focuses on unprivileged port candidates up to 65535.
