Why domain-check

  • 1,200+ TLDs out of the box — IANA bootstrap loads the full registry automatically. No config needed. 32 hardcoded TLDs work offline as fallback.
  • Dual-protocol engine — RDAP-first with automatic WHOIS fallback. IANA server discovery covers ~189 ccTLDs that lack RDAP (.es, .co, .eu, .jp).
  • Fast — up to 100 concurrent checks, streaming results as they complete. 2.7 MB release binary.
  • Domain generation — pattern expansion (\w=letter, \d=digit, ?=either), prefix/suffix permutations, and --dry-run to preview before checking.
  • 11 curated presets — startup, tech, creative, finance, ecommerce, and more. Or define your own in config.
  • Rich output — grouped pretty display, JSON, CSV. Registrar info, creation/expiration dates, and status codes with --info.
  • CI and automation friendly — --json/--csv to stdout, --yes to skip prompts, --force for large runs, automatic non-TTY detection.
  • Configurable — TOML config files, DC_* environment variables, custom presets, and clear precedence rules.
  • Agent-native — MCP server exposes all tools to AI coding agents (Claude, Codex, Gemini, Cursor, VS Code Copilot, and any MCP client).
  • CLI + library + MCP — same engine powers the CLI, domain-check-lib (Rust library), and domain-check-mcp (MCP server).
