Describe your startup to start

A few words is enough — what you're building, who it's for, or the problem you solve. We'll turn it into a wall of available domains.

Nomlen's startup name generator turns a short description of your startup into 100 brandable names, each with its domain already checked and ready to register — across the extensions startups actually use, like .io, .ai and .com.

Why this generator

Startup names you can actually register.

Most startup name generators hand you a list you then have to check by hand. Every name here arrives with its domain already verified against the registry.

Brief in, brand out

Type a plain description of the startup — what you're building, who it's for, the problem you solve — and the engine reads it for meaning instead of just shuffling your keyword.

Startup extensions first

Suggestions are weighted toward the extensions startups actually use — .io, .ai and .co — with .com always in the mix, so every idea fits how your company will be perceived.

Availability baked in

Each suggestion is checked against the registry as it's generated. The green tick means you can register it right now, not that it merely looks free.

Shortlist that survives

Heart the ones worth sleeping on. Your shortlist is stored in the browser and is still there when you come back to decide.

Startup naming, demystified.

A short description of the startup, not a single keyword. "AI fitness coaching app" gives the engine far more to work with than "fitness" — it can pull on the product, the audience and the category to build compounds, blends and affixes around all three.
Yes — unlimited names, no account, no signup. Generating names costs you nothing; you only pay if you decide to register a domain, and that goes to the registrar at their normal price.
It depends on your audience. .com still carries the most mainstream trust and is the cheapest to hold long-term. .io and .ai signal tech and are the default in SaaS and AI circles, but renew at a higher price every year. Every suggestion here shows its extension and availability, so you can compare the real options side by side.
Every suggestion is checked against registry availability data as it is generated, and only names marked available carry the green tick. A handful of extensions sit outside that feed and come back as unknown — those are shown without a tick so nothing is claimed that we can't confirm. Availability can change minute to minute, so the registrar's checkout is always the final word.
100 per brief. Hit "Generate more ideas" and the engine pulls a fresh batch biased toward different extensions — .io and .ai first, then .com, then .app, .dev and the rest — so the second batch explores namespaces the first one didn't reach.
Yes — a domain being available doesn't mean the name is legally clear. Run a quick trademark search (the USPTO's TESS in the US, or your country's trademark office) before you commit, especially if the name will be your company name. This tool checks domain availability, not trademarks.
Tap the heart on any card. Your shortlist is stored in your browser — no account needed — and is still there when you come back. Use the Saved toggle to filter the grid down to just your picks.
This page runs on the registry's own suggestion engine: fast, literal, and tuned for availability across the namespace. The AI domain generator hands your brief to a language model, which is slower but better at metaphor and coined words. Start here for volume, go there when you want a concept.
.com has been open for general registration since the mid-1990s, and speculators, brands, and parked pages have had thirty years to claim the dictionary. Short, pronounceable .coms are essentially exhausted — what's left is either premium-priced on the aftermarket or genuinely obscure. That's not a reason to despair; it's a reason to widen the field. A content site doesn't need .com the way a bank does. Extensions like .blog, .site, .co, and .online still have real, memorable names available at standard registration prices (typically $10–15/year at most registrars). This generator is weighted to surface those instead of showing you 100 taken .coms.
Ideally, yes — but don't contort a good name to force it. If your perfect name is taken in .com but free in .blog, taking ‘name.blog’ is better than settling for ‘get-name-online.com’. What matters is that people can find you from memory: one name, one obvious spelling, no hyphens if you can avoid them. If you must use a modifier (get, try, hq), keep it short and put it where it reads naturally. And whatever you choose, say it out loud five times — the phone test never lies.
Usually not — descriptive names date quickly and are hard to trademark, while coined or evocative names (the Vercel/Supabase pattern) can grow with the company. Let your tagline do the describing.
Aim for one or two syllables and under about ten characters if you can — short names are easier to say on a call, type from memory and fit in a logo.
Yes, but it costs: a new domain, new brand assets and lost recognition. It is far cheaper to spend an extra day naming well now than to rebrand after launch.
Domain availability first, then a trademark search in your category, then the matching social and GitHub/package names if your audience lives there.
For developer and AI audiences, yes — those extensions are well understood. If you sell to non-technical buyers, prioritise getting the .com, even if it means choosing a different name.
