About Unlock.domains
What Is Unlock.domains
Unlock.domains is a browser-based AI domain name generator built by LabStack LLC. You describe what you are building in plain language, and a large language model proposes brandable domain names spread across many extensions. As each suggestion arrives, the tool streams back an availability signal, so you see which names are open before you commit to anything.
The tool sits between an idea and a registrar. It works as a domain availability checker and a TLD search at the same time, and it does not sell or register domains itself. Instead, it hands off to a registrar of your choice, so the final purchase happens on a separate site.
Two limits are worth knowing. Availability labels are not guarantees. A name marked available can still turn out taken, or carry a premium price, by the time you reach checkout. The tool also runs only in the browser, so you need a connection, and its output is only as good as the description you give it.
Getting Started
- Open the site. There is no sign-up, account, or payment step.
- Describe what you are building in a sentence, or pick one of the example prompts shown on the page.
- Wait while the model generates names. Availability results stream in as each check finishes.
- Refine the list with a follow-up message if you want shorter names, a different tone, or a specific extension.
- Save the names you like, then pick a registrar from the list to check the final price and register.

Key features
AI name generation from a plain description
The core of the tool is a prompt box. You describe what you are building in ordinary language, such as a sleep therapy journal or a robotics kit subscription, and the model returns brandable names built around that idea. There are no filters or keyword grids to fill in first. The clearer your sentence, the more usable the names tend to be.
Live availability checks across 1,400+ TLDs
Each suggestion comes with an availability signal. The tool routes more than 1,400 public extensions, including .com, .io, .dev, .app, .ai, .co, .shop, and .coffee. Names are labelled available, possibly available, or taken, and the status streams in as each check completes rather than waiting for the whole batch.
Confidence-aware status labels
The tool does not treat every check as equal. It uses RDAP, the registries' own lookup protocol, for authoritative answers, falls back to WHOIS where needed, and keeps a conservative DNS check for the rest. When a result is uncertain or the extension only offers a DNS signal, the name is marked possibly available instead of claiming a firm answer.
Follow-up refinement with context
You can keep the conversation going. Follow-up messages retain context, so you can ask for shorter names, a calmer tone, or a specific extension, and the next set of results adapts. This turns a one-shot list into an iterative naming session.
Saved list and batch actions
Names you like can be saved to a list inside the page. From there you copy the whole set or open registrar links in a batch. Your saved domains, theme, and preferred registrar are stored in your browser, so the list stays with you without an account.
Registrar handoff with affiliate links
The tool connects to Dynadot, Spaceship, Name.com, Namecheap, and NameSilo. When you pick one, the link takes you to that registrar to confirm current availability, premium status, and price. The tool earns a commission on some of those links, which costs you nothing extra.
Pros and cons
Pros
- No sign-up required: you open the page and generate names, with no account, email, or payment step.
- Broad extension coverage: more than 1,400 public TLDs are routed, so a name can be checked beyond the usual .com.
- Honest availability labels: uncertain checks are marked possibly available instead of being presented as confirmed.
- Iterative flow: follow-up prompts keep context, so a weak first list can be shaped into something usable.
- Free to use: generation and availability checks cost nothing, and payment only happens at the registrar.
Cons
- No guarantees: a name marked available can still be taken or carry a premium price at checkout.
- Browser only: there is no mobile app or offline mode, so a working connection is required.
- Results depend on the prompt: a vague description leads to weaker names, and quality varies run to run.
- No registration on site: you cannot buy a domain here, so the last step always moves to a separate registrar.
- Affiliate links: some registrar links earn the company a commission at no extra cost to you.
