The tldx is a lightweight command-line tool for checking whether domain names are available. It can test one or more domains in a single command and quickly reports whether each name is available. This tutorial explains how to install tldx on Ubuntu 26.04.

First, retrieve the latest release version from the GitHub repository of the project:

TLDX_VERSION=$(curl -s "https://api.github.com/repos/brandonyoungdev/tldx/releases/latest" | grep -Po '"tag_name": "v\K[0-9.]+')

Next, download the corresponding Linux release archive and extract the tldx executable into /usr/local/bin:

After installation, verify that the tldx has been installed successfully by checking its version:
