tldx is a fast Go CLI tool for brainstorming and checking domain name availability in bulk using RDAP, DNS, and WHOIS. It generates keyword permutations with prefixes, suffixes, and TLDs, supports regex patterns, multiple output formats, and includes an MCP server for AI agents.
Use cases
- check if a domain name is available
- bulk check domain availability
- brainstorm domain names for a startup
- find available 3-letter domains
- generate domain name permutations with prefixes and suffixes
- find domains for sale
- check domain availability from the command line
When to choose
- you need fast, concurrent bulk domain availability checks locally
- you want to generate many domain name permutations quickly
- you want an MCP server so AI agents can check domains
- you need machine-readable output like JSON or CSV for pipelines
When to avoid
- you need a full domain registrar or purchase flow
- you need a GUI-based domain search experience
- you need guaranteed accurate WHOIS data for legal purposes, since RDAP coverage varies by TLD
