Lobby Domains

Lobby Domains is a free domain name generator and RDAP checker that runs on-device AI in Chrome.

Lobby Domains is a free domain name generator and RDAP checker designed to help users find names for businesses, side projects, or products. It uses Chrome's built-in on-device AI to generate ideas locally while checking domain registrations in real time using the Registration Data Access Protocol. Users can describe their project, filter extensions, set naming constraints, and explore variations such as shorter or easier-to-spell options. The tool allows users to star favorites, compare up to four names, export shortlists as CSV or JSON, and save sessions locally in the browser. It operates without accounts, cloud sync, or remote tracking, while supporting WebMCP for compatible agent integrations.
