Our verdict on Domain Hunter
Domain Hunter is a free, open-source browser application for checking domain availability in bulk through RDAP registry lookups. It is aimed at users who need to evaluate large sets of names, generate alternatives, compare registrar pricing, and export results without creating an account. The tool supports up to 3,000 names per bulk check and includes five domain-name generators, making it suited to domain research workflows that begin with either an existing list or new naming ideas.
Pricing is straightforward: Domain Hunter is free and open source. Its feature set includes registrar price comparisons and three-year total-cost calculations, so users can assess availability alongside longer-term registration costs. Results can be exported as CSV, TSV, or Markdown. The five generators add breadth to the naming workflow, while RDAP-based lookups provide the stated method for checking registry availability. These capabilities make it a practical fit for open-source users and teams that want a large search volume without a paid plan structure.
The application runs client-side in a browser and can be built as a standalone HTML file that works from file://. A Node CLI and MCP server extend the same checking logic beyond the browser, while the hosted web application avoids accounts, servers, API keys, and tracking. Its main constraint is scope: coverage is limited to 148 curated TLD zones, and API access is not provided. Users who need broad zone coverage, a conventional API, or AI-assisted naming should choose another tool. Domain Hunter fits buyers prioritizing bulk searches, open-source access, exports, and registrar cost comparisons.
