A SaaS name has to be free in four places at once
A SaaS name is not one namespace, it is four. The domain your customers type, the GitHub organisation your code and docs live under, the package namespace your SDK or CLI ships to, and the product directories where people go looking for alternatives to you. A name that is free in three of them and gone in the fourth is the one that costs you a rename six months in.
This tool queries all of them live when you press check. Nothing is pre-computed, and nothing you type is stored.
What this SaaS name checker actually checks
Most "is this name taken" searches are a domain lookup with a nicer form on top. The domain is the loudest signal, not the only one — and for a SaaS, it is usually not the one that forces the rename.
- Domains — .com, .io and .ai, the three a SaaS team actually decides between
- GitHub — whether the organisation handle exists, and separately whether a user already holds it
- npm and PyPI — the package namespace your SDK, CLI or client library would publish to
- Product Hunt — whether a product has already launched under that slug
- Crunchbase — whether a funded company is already operating under that name
The .com is not the whole domain question
For a SaaS the three extensions worth weighing are .com, .io and .ai, and they do not carry the same weight. The .com is still what a customer types from memory and what an enterprise buyer expects to see on an invoice. The .io reads as native to developer tools and is widely accepted there, but it is a second choice everywhere else. The .ai is now the default for AI products and is priced accordingly.
Losing the .com is survivable if your buyers are developers and you can hold the .io or .ai cleanly. Losing all three to an active company is a different result — that is not a domain problem, it is a signal that the name is occupied.
A taken GitHub org or npm package is a real problem, not a nitpick
These two get skipped because they feel like edge cases at naming time. They are not. The npm and PyPI namespaces are globally unique and permanent — if your package name is taken you ship under a scope or a mangled variant forever, and every install command and import line in your docs carries the compromise.
The GitHub organisation matters for the same reason but in public: it is the URL on your docs, your examples, your issue tracker and every Stack Overflow answer about you. Note that this tool distinguishes the two cases — an existing organisation is a hard conflict, while a dormant personal account holding the handle is worth knowing about but is sometimes negotiable.
Available is not cleared
Everything here answers one question: has somebody already claimed this? That is not the same question as whether you are allowed to use it. Trademark rights attach to a mark within a class of goods and services, held on registers this tool does not search — so a name can be free on every platform above and still belong to somebody else in your category.
The order that saves money is: screen for occupancy first, because it is fast and free and eliminates most candidates; then run a trademark search on the two or three that survive; then register the domain and reserve the org and package handles the same day. Renaming a shipped SaaS means new URLs, new package names, broken inbound links and lost search ranking.
Frequently asked questions
Yes, entirely. There is no account, no email and no credit card, and results are not stored. The full NameSpyAI report — which adds trademark and web-presence checks — is the paid product.
They can and they do, particularly across different categories and countries. Nothing stops you shipping a name someone else already uses. What it costs you is compound: you split search results with them, you compete for the same branded queries, and if they hold a registered trademark in your class they can force the rename at the point where it is most expensive.
Because they are different problems. An existing organisation usually means an active project or company is already using the name publicly, which is a genuine conflict. A personal user account holding the handle is a weaker signal — plenty are dormant, and handles are occasionally released or transferred. The tool reports them separately so you can tell which one you are looking at.
Because you will probably want one, and the namespace is claimed on a first-come basis and effectively never released. Finding out at naming time costs nothing. Finding out on the day you publish your client library means shipping under a scope or a variant spelling that then appears in every install command and code sample you ever write.
Those are the three a SaaS team genuinely weighs against each other: .com for reach and credibility, .io as the accepted developer-tool alternative, .ai for AI products. A longer list mostly adds extensions nobody would actually launch on, and a wall of chips is harder to read than three real answers. The full NameSpyAI report sweeps sixteen.
The source did not answer clearly — usually a timeout or a rate limit on their side. It never means available. Product Hunt and Crunchbase are the likeliest to do this, since both are checked by requesting the public page. Re-run the check in a minute, or verify that one source by hand.
Available is not the same as cleared
This tool covers three domains, GitHub, the package registries and two product directories. The full NameSpyAI check adds US (USPTO) and EU (EUIPO) trademark search, Google web results, Instagram, Reddit, LinkedIn, YouTube and the social handles — across sixteen extensions — then scores every signal into one verdict you can act on.
