Vercel lets anyone check domain availability and pricing without signing in

What changed

Vercel has opened domain discovery to everyone. According to a changelog entry on the Vercel blog dated September 29, 2026, you can now find domain names and check their availability and pricing without signing in to a Vercel account or providing an access token. The capability is exposed through two surfaces: the Vercel CLI and the Domains Registrar API.

Searching from the CLI

On the command line, the domains search command takes a keyword or a domain fragment and returns suggestions. Vercel's own example looks like this:

vercel domains search acmesite --limit 5

That invocation returns up to five suggestions built around the keyword acmesite. It targets the exploratory phase of naming something — you have a rough word in mind and want to see which variants are free before committing to one.

Bulk checks through the API

The API side is built for exact lookups at scale. A POST request to the registrar domains search endpoint on Vercel's API accepts a JSON array of exact domain names, and the changelog says a single request can carry up to 200 of them. The documented example passes three — example.com, example.dev and example.app — but the batch limit suggests the endpoint is intended for larger sets.

For each name in the list, the response reports whether it can be registered. Where a domain is available, the response also includes its registration price and its renewal price, so cost comparisons across many candidates can happen in one round trip instead of one lookup at a time.

What still requires a login

The boundary is drawn clearly in the changelog: authentication is still required to buy or manage domains. What is public now is discovery only — searching, availability and pricing. Registering a name, transferring one or changing its settings still means signing in.

Vercel also points readers to a public web-based domain search for those who prefer a browser over the terminal, and notes that Pro plan customers can claim a free domain.

Why it matters

Domain checks are a routine chore for developers. Naming a side project, standing up a preview environment or scaffolding a new service almost always starts with the question of whether a name is free and what it costs, and that check tends to happen inside scripts and tooling rather than in a browser. With Vercel framing this as newly possible without signing in, the practical effect is that even the simplest lookup no longer forces anyone to create a token, rotate it or risk leaking it into a repository.

Removing authentication from the read path also lowers the barrier for third-party tooling. A project scaffolder, a name generator or an internal dashboard can now surface availability alongside registration and renewal costs in bulk, with a single unauthenticated HTTP call, and without requiring its users to hold a Vercel account just to see results.

For teams already inside the Vercel ecosystem, the change shortens the path from picking a name to buying it, while the transactional part — purchasing and managing domains — stays gated behind an authenticated account, which is where it belongs.
