Agent Lab Domains

Domains your AI agent can buy,
and wire up for you.

Built an app with AI? Find it a name: search, buy and connect it, with DNS and HTTPS handled for you and privacy included.

Or just tell your AI tool: "Point acme.com at this app." Connect MCP →

Bought means live

Buy a domain, and it's already pointing at your app

Domains bought on Agent Lab use our DNS, so the verification record, the pointing record and the HTTPS certificate are set the moment you buy.

  1. Search

    Type a name and see every ending's availability and price at once.

  2. Buy

    Check out with your workspace's payment method, with privacy on by default.

  3. Auto-configure

    The TXT verification record and the CNAME or A record to your app are written for you.

  4. Live

    HTTPS is issued automatically and the domain follows your main version through go-lives and rollbacks.

Endings and prices

Pick an ending, see the price

Each ending is run by a different registry with its own rules. Prices are shown again before checkout, with no add-ons.

EndingPriceRegistry ruleGood for
.comUS$14 / yearRun by Verisign; the most common endingA company's or product's main domain
.aiUS$175 / 2 yearsAnguilla's country domain; at least 2 years per registrationAI products
.devUS$15 / yearGoogle Registry; HTTPS-only for the whole endingDeveloper tools and docs
.appUS$17 / yearGoogle Registry; HTTPS-only for the whole endingApps and product pages
.twUS$38 / yearTaiwan's country domain, run by TWNICBrands serving people in Taiwan
.com.twUS$25 / yearTWNIC's commercial domain; needs a Taiwan company numberTaiwan companies

Prices exclude applicable taxes. WHOIS privacy, DNS hosting and HTTPS certificates are included at no extra cost. The whole .dev and .app endings are on browsers' HSTS preload list, so they open only over HTTPS.

Three ways in

Buy and connect wherever you already work

One account and one wallet: every domain you buy, wherever you bought it, shows up in the workspace's domain list.

On the web

Search and register right on this page. Grab a good name now and decide which project it points at later.

In the Deploy console

A project's Add custom domain dialog gets a Buy a new domain tab: search, buy and connect, in one dialog.

From your AI tool (MCP)

Say the word in Claude Code or Codex and the Agent Lab MCP server connects the domain to your project, checks the verification record and confirms HTTPS is issued.

Already have a domain?

A domain bought elsewhere connects too

A domain from Cloudflare, GoDaddy or any registrar connects to a Deploy project with two DNS records, no transfer needed. Custom domains start on the Pro plan.

  1. Verify the domain

    Add the domain to your workspace and one TXT record (_agentlab-verify) at your DNS. One verification covers the whole workspace and its subdomains.

  2. Point it at the project

    A subdomain gets a CNAME to cname.agentlab.run; the root domain gets an A record to the IPv4 shown. On Cloudflare, set it to DNS only (grey cloud) first.

  3. HTTPS, automatically

    Check DNS once it has spread and the certificate is requested for you; the domain follows your live version through releases and rollbacks.

Included

Everything a domain should come with

No add-on list, and no fees that appear at checkout.

HTTPS, automatically

A certificate is issued the moment the domain connects to your app and renews itself; nothing to install.

WHOIS privacy

Public lookups see proxy details only, so your name, email and phone stay out of scrapers' hands.

DNS hosting

Edit any record in the console; the records that connect Deploy are maintained for you.

Email records in one click

Sending from this domain? Add SPF, DKIM and DMARC in one click, ready for MAAC Go Email.

FAQ

Before you buy

What is Agent Lab Domains?
Agent Lab Domains is the domain service of Agent Lab Deploy. This page checks for free whether a name can be registered in .com, .ai, .dev, .app, .tw and .com.tw, straight from each registry; once a domain is connected to an app on Deploy, its HTTPS certificate is issued automatically.
How accurate is "available" here?
Each result is a live lookup against the ending's official registry over RDAP, not a cached list. Reserved and premium names are priced differently; the price at checkout is the one that counts.
Why do .dev and .app need HTTPS?
Both endings are on browsers' HSTS preload list, so browsers only connect over HTTPS. A domain connected to Deploy gets its HTTPS certificate automatically, so there is nothing extra to do.
What's the difference between .tw and .com.tw?
Both are Taiwan domains run by TWNIC. .com.tw is the commercial domain and needs a Taiwan company registration number; .tw is the shorter country domain.
Does a domain renew automatically?
By default, yes. We email you 30 and 7 days before it expires and charge the workspace's payment method at renewal; switch auto-renew off for any domain in the console.
Why is .ai more expensive, and sold for 2 years?
.ai is Anguilla's country domain. Its registry charges a high wholesale price and requires at least 2 years per registration, so we show the 2-year price as it is.
Can I get a refund if I buy the wrong one?
A registration is written to the registry immediately and can't be undone, so domains are generally non-refundable. Checkout shows the full domain and price once more, and nothing is charged until you confirm.
