Search domains across their lifecycle, from newly registered to deleted.

DomainKits is a domain search and lifecycle intelligence suite powered by ABTdomain. It covers over 370M domains (250M+ gTLD domains and 128M+ ccTLD domains across 1,200+ extensions), tracking names from registration through active use, expiration, deletion, and aftermarket resale.

DomainKits works with domain-level data, such as registration dates, EPP statuses, DNS records, and aftermarket listings. In line with GDPR, we do not collect or share registrant data.

DomainKits covers each stage of a domain's lifecycle with six specialized search engines and a set of lookup tools:

• Newly Registered Domains (NRDs): refreshed every 15 minutes across a rolling 60-day window to catch market trends early.
• Active Domains: the inventory of currently registered domains across gTLDs and ccTLDs.
• Aged Domains: a filtered view of active names with 5 to 20+ years of continuous registration history.
• Expired and Deleted Domains: follow names through grace period, redemption, and pending delete, and find previously registered names released after deletion.
• Marketplace Search: for-sale listings aggregated across 10 aftermarket marketplaces.
• Tools Kit: WHOIS, DNS, subdomain, backlink, safety, and typosquatting checks, plus TLD Search and bulk checks to compare extensions and screen domain lists.

Yes. Core search engines and lookup tools are free for everyday domain research within basic usage limits.

• Free account: a free account adds higher daily limits and a personal key for the MCP Server, and the open-source Agent Skills are free to install.
• Paid plans: Lite, Advanced, and Premium add more ccTLD coverage, bulk exports, and change alerts, plus Developer API, SDK, and CLI access on eligible plans. See membership tiers for details.

Abuse and attempts to bypass usage limits are not allowed. Please follow our Terms of Service.

DomainKits is built for AI workflows:

• MCP Server: connect Claude Desktop, Cursor, Gemini CLI, ChatGPT, or other MCP-compatible clients to our remote MCP endpoint (https://api.domainkits.com/v1/mcp) so your AI can query live WHOIS, DNS, and NRD data in plain English instead of guessing.
• Agent Skills: load the open-source SKILL.md playbooks in Claude Code, Cursor, or your project instructions to run multi-step tasks such as startup naming, acquisition due diligence, and brand protection.
• DomainKits GPTs: search for available domains and run reverse NS lookups inside ChatGPT.

Developers and data teams can plug DomainKits into backend scripts, internal dashboards, and automated workflows:

• REST API and SDKs: Bearer-key authentication, an OpenAPI spec, and official SDKs for Python, TypeScript, and Go.
• DomainKits CLI (dk): an open-source single binary for macOS, Linux, and Windows to run searches, WHOIS, and DNS lookups from your terminal.
• n8n community node (n8n-nodes-domainkits): add domain search and intelligence nodes to visual n8n automation workflows.
• Daily NRD files: download the daily NRD lists as gzip-compressed .txt.gz and .csv.gz files.

API and CLI access require an API key and an eligible paid plan. See the API documentation for endpoints and rate limits.
