Fast CLI to bulk-check domains via RDAP & MCP
77 followers
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.

@brandonyoungdev this is great; do you hit DNS directly, or what are you querying to pull your results?

@chrismessina tldx uses RDAP primarily to check. RDAP is the modern replacement for WHOIS, but not every tld has adopted it yet.
Then if that fails, we fallback to DNS and WHOIS. DNS is fast and we just do a lookup host. If that fails, we do a WHOIS lookup for TLDs that still support WHOIS.
Between all 3, we get a good picture of if a domain is available or taken. Plus, since it's not hitting a registrar's server, you don't have to worry about a good domain being sniped and then re-sold as a premium domain.
