Our verdict on Tiny Startups Bulk Domain Checker

Tiny Startups Bulk Domain Checker is a free, browser-based tool for checking domain availability in bulk. It lets users enter a base name, expand it across .com, .io, .co, .ai, .app, .dev, .xyz and .net, then check up to 50 domains in one request. The tool is suited to founders, marketers and anyone making quick naming checks without wanting to create an account or obtain an API key. It runs on the web and links available domains to Namecheap for registration.

The Free plan includes bulk domain availability checking and RDAP registry lookups. The tool queries official RDAP registries directly and performs parallel availability lookups, which keeps the workflow centered on checking many options in one request. Results can include Unknown when registry responses are ambiguous, giving users a distinct status instead of treating every unclear response as available or unavailable. For straightforward checks across the supported extensions, the combination of bulk entry, direct registry queries and no signup keeps the process focused.

Its scope is deliberately narrow. The extension set contains eight options, and the category specification describes domain variations as basic. The tool also does not provide domain generation or export features, so it is better for validating a short list than for developing a broad naming pipeline or moving results into another workflow. Choose it for fast, no-cost availability checks across common extensions; choose a broader domain search tool if you need more extensions, richer name generation or export support.
