The footer counter on dcs4.com read 1,679,614 domains checked on October 24, 2026. That is almost exactly every four-character combination of letters and digits (36 to the fourth power is 1,679,616), so the index covers the whole space rather than a sample. Of those names, 577,409 were listed as available.

Search takes wildcards. n* finds names that start with n, qu?? fills in two unknown characters, and *ak finds names that end in ak. Each result shows whether the name recently dropped, its brand score and when it was last checked. A separate panel follows names close to expiry, 74,311 at the time, with the current registrar and expiry date.

The default view sorts by newest, and the first page was all mixed names like 9z12.com and s41l.com with low brand scores. If you want something pronounceable, the letters-only toggle and the brand score filters do most of the work. For names that aren't free yet, you can watch a pattern and get an alert when a match drops.

Browsing the index is free and needs no card. Buying or sniping needs an account, and the privacy policy says the site collects registrant details such as name, address and phone so Spaceship can register domains for you, with Stripe handling payments. Sniping costs $19 per domain, and $15 comes back if the snipe fails. Pro is $29 a month and adds dropped-domain search, full list exports, email alerts on wins and losses, and an AI chat assistant. The policy says chat messages go through OpenRouter to the model providers it uses.
