Name Checker
Check a brand, startup or project name everywhere at once: domains in the main extensions, the same username on social and developer platforms, and the package name in npm, PyPI and other registries.

Interactive intelligence tool
Run the check, then ship the workflow
Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.
Review decision-ready signals
Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.
Automate the workflow that works
Use the request and response examples to turn a one-off check into an API call or recipe.

What this tool helps you decide
Each page is shaped around a practical operational question, not just a raw lookup.
See the current DNS, registration, security, pricing, or reputation evidence.
Compare the result with related checks so the next move is easier to trust.
Copy examples, open linked tools, or move into API documentation when you need scale.
Trust signals before you integrate
Transparent docs, authenticated requests, and visible reliability details make it easier to evaluate DomScan before you ship.

Key Features
Domains, handles and packages
One search covers domain extensions such as .com, .io and .ai, 20 major platforms and 7 package registries.
A clear verdict
See at a glance whether the name is free everywhere, mostly free or contested, with a score from 0 to 100.
Evidence, not guesses
Every result shows its own status. Anything that could not be confirmed is shown as unknown, never as free.
Example request
GET /v1/name-check?name=acmeflow&tlds=com,io,aiBuilt on the same API
The browser experience previews DomScan's structured endpoints, so teams can validate a use case before writing code.
Frequently asked questions
Which platforms and registries are checked?
Domains in .com, .io, .ai, .co, .app, .dev, .net and .org, 20 social and developer platforms such as Instagram, TikTok, X and GitHub, and the npm, PyPI, crates.io, RubyGems, NuGet, Packagist and Homebrew registries. The API lets you choose your own lists.
Does free mean I can register the name?
Free means nothing currently uses the name. Some platforms and registries also refuse names that are too similar to existing ones or reserved, so a free result is a strong signal, not a guarantee.
Why are some results unknown?
A platform can block or limit automated checks. When that happens the result is shown as unknown rather than guessed, and it does not count towards the score.
