Quick Links: Installation Quick Start Use Cases Output Formats Presets Configuration Automation Library MCP Server FAQ Contributing 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 powe","default_branch":null,"files":null,"tree":[],"storefront":"/r/saidutt46","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/saidutt46/domain-check/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
