Finding a good domain is half the battle. tldx is a blazing-fast, concurrent CLI tool that generates and checks domain availability in bulk via RDAP. Mix keywords, prefixes/suffixes, or regex, and stream results to stdout, JSON, or CSV. Plus, tldx includes an MCP server, empowering AI agents (like Claude) to brainstorm and verify domains for you automatically! Install via Homebrew (brew install tldx). Say goodbye to rate-limits and legacy whois parsing. 100% Free & Open Source in Go.
tldx is great for bulk RDAP domain checks. If you’re still exploring names, try Namefinder.ai, Namify, or StickyBrand for AI ideas. Need deeper vetting? Brandsnap.ai adds trademark, domain, and social handle checks.
