Discovering the perfect domain name is a crucial step for any project. tldx is a blazing-fast, concurrent command-line interface (CLI) tool that streamlines this process by generating and checking domain availability in bulk using the modern RDAP protocol. You can effortlessly mix keywords, prefixes, suffixes, or even regular expressions to generate a wide array of potential domains, and then stream the results directly to stdout, JSON, or CSV format. Additionally, tldx incorporates an MCP server, giving AI agents, such as Claude, the power to automatically brainstorm and verify domain names on your behalf. Installation is simple via Homebrew (brew install tldx). Bid farewell to frustrating rate-limits and outdated whois parsing. tldx is 100 percent Free and Open Source, built with efficiency in Go.
