Our verdict on Flash Domain Search
Flash Domain Search is a web-based domain research tool for founders, agencies, brand teams, domain investors, and others naming websites or products. It checks availability across 328 domain extensions, combines registry RDAP and DNS signals, and adds domain generation, research, copying, and CSV export. The web interface suits users comparing names manually, while the API provides availability checks and deterministic name ideas for eligible sites.
Its strongest advantage is breadth at no cost. The Free plan includes availability search, domain name generation, domain research, and bulk domain search at $0 per month. Generation offers five idea styles, while research can cover registration data, DNS records, hosting signals, history, and social-handle availability. The bulk tool accepts up to 60 names and can check up to 900 name-extension combinations per run, giving small naming projects a practical way to compare options without checking each extension individually.
The main constraint is scale and ecosystem access. Bulk uploads are not supported, so larger lists must be entered within the stated 60-name limit. Although API access is available, it is private to sites owned by the FlashDomains owner rather than a generally available developer integration. Choose Flash Domain Search when free, wide extension coverage and domain context matter more than enterprise-scale workflows. Teams needing larger imports, broadly accessible API credentials, or a paid support and capacity structure should consider a tool built around those requirements instead.
