Getting started

How do I check if a domain is available for free?

Paste your names into axath, pick the extensions you care about, and the checker answers straight away. No account is needed to start. Every result comes from the registry itself over RDAP, with a live DNS pass in front of it, and each row records which of the two confirmed the answer. Checking is free and stays free, with no cap on how many checks you run.

What is the best bulk domain checker?

The one that tells you the truth at volume. axath checks thousands of names in a single batch against authoritative registry data, streams the results as they arrive rather than making you wait for the slowest lookup, and separates a confirmed answer from an ambiguous one instead of rounding everything up to available. Extensions without a dependable public registry service are marked for review rather than guessed at, which means the available results you get are results you can act on.

What can I do without signing in?

Most of it. You can check up to 500 domains in a session across 5 extensions, generate name ideas, keep a shortlist of 10 names in your browser, and open any result at a registrar. Nothing is watermarked, time limited or held back to force a signup. An account exists to make that work permanent rather than to unlock the basics.

How do I report a bug or ask for a feature?

Support handles anything account, billing or bug related, and every message is read. Feature requests go to the public roadmap, where you can also vote on what other people have asked for, so the next thing built is the thing most people are waiting on rather than the loudest single request.

Checking domains

Can I check multiple domains at once?

That is what it is built for. Paste one name per line, a comma-separated list, or full domains such as example.com, select your extensions, and the whole batch is checked in one pass with controlled concurrency. Up to 5,000 domains in a single session on Pro, 2,000 on a free account, and 500 without signing in at all.

Which TLDs does axath support?

Hundreds of extensions, checked through DNS and registry-operated RDAP services. That includes .com, .net, .org, .io, .dev, .app, .ai, .xyz, .me, .info, .biz, .us, .uk, .ca, .de, .fr, .au, .in, .tech, .online, .shop and .store, along with many more. A small number of extensions, .co and .gg among them, publish no dependable public registration data. Those are marked for review rather than reported as free, so you never register against an answer the registry never gave.

How many extensions can I check at the same time?

5 at once without an account, 10 on a free account, 20 on Pro and 25 on Scale. Many registries answer slowly, so a tighter selection keeps a check fast. Checking one name across every extension in a single pass is how you find out that the .com went in 2004 but the matching .io is still open, which is the kind of thing that changes a naming decision.

Does axath let me register domains?

axath is research rather than a registrar, which is exactly why it can stay neutral about where you buy. Every available result carries the cheapest published price for that extension and a direct link to register, so you go from a name to a registrar in one click without being steered toward whoever pays the most for the placement.

Could searching here cause someone else to buy the domain first?

Not through us. Searched names are never sold, never registered by bots, and never forwarded into registrar marketing feeds. Domain front running is a real problem with tools funded by the registrars they send you to, which is one reason this one is funded by subscriptions instead. A lookup does reach a DNS resolver and the registry, because that is what a lookup is, and those are the only parties that see the name.

Results and accuracy

What is RDAP and how is it better than WHOIS?

RDAP, the Registration Data Access Protocol, is the standardised replacement for WHOIS. WHOIS returns plain text over port 43 in a format that differs from registry to registry, which is why tools built on it disagree with each other. RDAP returns structured JSON over HTTPS with proper error codes, internationalisation and access control, so an answer can be read precisely rather than pattern-matched. It is defined in IETF RFCs 7480 to 7484 and 9224, and it is what axath queries.

How accurate are the results?

Every answer comes from authoritative registry data: the registry's daily zone file, DNS, and the registry record over RDAP or WHOIS, the same sources a registrar checks. Where the registry gives a clear answer, so does axath. Where it does not, the result is marked Likely available or Not verified and linked for you to confirm, rather than being presented as available. That distinction is the product: a shorter list of answers you can trust beats a longer list you have to re-check. Domain availability still changes by the minute, so the registrar remains the final confirmation before you buy.

What do the result states mean?

Available means the registry answered that the name is not registered. Likely available means the name is not in the zone file and has no DNS, but the registry has not confirmed it, for example in a large check or when the registry limits lookups; confirm it at the registrar. Registered means the zone file, DNS or the registry record shows the name, usually with registration and expiry dates. For sale means it is registered and listed on a marketplace with a price. Not verified means no usable answer came back yet. Error means the lookup failed outright and can be retried. More than two states is the whole point, because a two-state tool has to file every ambiguous case under available.

What should I do if a domain shows as "Not verified"?

Not verified means the registry did not return a clear answer, usually because access was denied, the request was rate limited, or the response was malformed. Press retry and it is usually resolved. If it stays unverified, the result links straight to a registrar so you can confirm it in one click. Showing it this way is deliberate: the alternative is calling a domain available when nothing confirmed that it is.

Are results cached, and how fresh are they?

Lookups are cached for up to 24 hours so a repeated check does not hammer a registry that rate limits it, and so a second pass over a long list returns quickly. Errors are never cached as a verdict. With your consent, recent results are also kept in your browser between visits to make repeat searches instant. Every result carries the time it was checked, so you always know how old an answer is.

Why does a registrar sometimes disagree with the result?

Usually one of three reasons. The name is premium, and the registry publishes it as available at a price far above the standard rate. The registrar has reserved it internally. Or it was registered in the minutes since the check ran. The registry record is the source of truth for whether a name is taken, but the registrar decides whether it will sell it to you and at what price, which is why every available result links out for confirmation.

Tools and features

What does Brand Check do?

It answers the questions a domain lookup cannot. One name is checked across social handles and developer platforms, every supported extension, spelling overlaps in eight European languages, public web archive captures and Certificate Transparency records, official trademark registers covering the United States and the European Union, and a visual preview of the name as a wordmark, a favicon and an app icon. It is the difference between a domain being free and a name being usable.

What does Domain Hub do?

It watches domains over time instead of answering once. Add names you own or names you are waiting on, and their registry status, registrar, expiry date, status codes and DNS records are re-checked on a schedule, with every meaningful change recorded alongside the value it replaced. Domains close to expiry or already in a drop phase are checked more often, and each one carries an estimated release date built from the standard registry phase lengths.

How does the name generator work?

Three ways, and they are good at different things. Algorithmic generation expands your keywords through naming patterns, which is fast, repeatable and scored. Dictionary search finds real words matching the shape you want. AI generation reads a full description of the business and returns concept-aware suggestions. All three come back already checked against the extensions you selected, so you are choosing between names that are actually available rather than names that merely sound good.

What is the difference between the shortlist and a project?

The shortlist is a holding pen for names you are still comparing, kept as a snapshot from when you saved them. A project is where the survivors go: named collections with notes attached, share links, and file import on Pro. Domain Hub is the third stage, for names you have committed to and want monitored. Shortlist to decide, project to organise, hub to hold.

Can I share my research with a client or a co-founder?

Yes. Any project can produce a read-only share link that shows the names, descriptions and domain lists without giving access to your account. Free accounts can have 3 active links per project, Pro 10 and Scale 25. Links can be revoked at any time, and revoking one takes effect immediately.

Can I import a list of domains I already own?

Yes, on Pro. Import a file of domains straight into a project, or add them to Domain Hub to have their expiry dates, registrars and DNS records tracked from then on. For a portfolio of any size this is usually the fastest way to find out which names are closer to expiry than you thought.

Plans and billing

Is axath really free?

The checker is free, with no limit on how many checks you run and no account required to use it. A free account adds cloud-synced history, a larger shortlist, projects, bulk copying and CSV export. Pro raises the per-check capacity, unlocks file import, more projects and a year of history, gives more Brand Checks a day and a larger Domain Hub, and starts with 14 days free.

What do I get with Pro?

Checks of up to 5,000 domains across 20 extensions at once, 25 Brand Checks per day, Domain Hub monitoring for up to 100 domains, 25 projects of 500 domains each, a year of history with pinned searches kept for good, file import, a 50-name shortlist, 50 algorithmic generations per day, and 50 AI generations per day. The pricing page carries the current figures for both billing cycles.

What payment methods can I use?

Checkout is handled by Stripe. Credit and debit cards are accepted everywhere, and Stripe additionally presents the wallet and local payment options it supports for your country and currency, which appear automatically on the checkout page. You can pay in euros or US dollars, monthly or yearly, and the currency is chosen before you reach checkout.

Is my card information safe?

Your card never touches our servers. Payments run through Stripe-hosted checkout on PCI-DSS certified infrastructure, and Stripe collects the card number and security code directly. What we receive and store is the payment status, a customer reference, the plan and the transaction timestamps, which is what is needed to give you access and to satisfy tax record-keeping duties.

Do I get an invoice, and can I add a VAT ID?

Yes to both. A billing address is collected at checkout and there is a field for a VAT or tax ID, so a business purchase is documented correctly from the first payment. Invoices and receipts are emailed automatically, and every past invoice stays available in billing management inside your account settings.

Do you offer discount codes?

Your first paid plan starts with 14 days free, and new accounts may see a one-time welcome offer, which is applied at checkout automatically. Occasionally a discount code is shared; enter it in the code field at checkout. The yearly cycle is always cheaper than paying monthly, and the saving is shown on the pricing page.

How do I cancel my subscription?

Open billing management from your account settings and cancel there. Cancelling stops the renewal rather than cutting you off, so Pro stays active until the end of the period you have already paid for, and that date is shown in your settings. If you change your mind before it arrives, reactivating takes one click and does not start a new charge.

Can I get a refund?

Your first plan starts with 14 days free, and nothing is charged during them, so changing your mind then costs nothing. Consumers in the EU also have a 14-day right of withdrawal, which you can use online on the cancellation policy page; anything paid is refunded within 14 days to the same payment method. For a plan paid from the first day, a withdrawal partway through may be settled for the days used. The cancellation policy page sets this out in full, including a model withdrawal form.

What happens to my data if I stop paying?

Nothing is deleted when a subscription ends. Projects, history and shortlist stay where they are, and the free plan limits apply again to what you add from that point. Monitoring in Domain Hub stops running and the domains you added remain listed. Resubscribing picks up exactly where you left off.

Can I export the results?

Yes. Individual results can be copied without an account. Signed-in users can also copy a complete filtered list or export it as CSV with the domain, extension, status, response time and timestamp on every row, so a check can go straight into a spreadsheet, a client report or your own tooling.

Account and privacy

Do I need an account to use axath?

No. The checker works immediately, and your shortlist and recent checks are kept in your browser. Signing in is what makes that research permanent: history, shortlist and projects sync across devices, and nothing is lost when you clear a browser or move to another machine.

How do I sign in?

With Google, with GitHub, or with your email and a password. Signing up by email asks for a 6-digit code once to confirm the address. Forgot password sends a code to set a new one. Passwords are never stored by axath: the sign-in provider keeps only a salted bcrypt hash.

Is my domain research private?

Your searched names are never sold, never registered by bots, and never forwarded into registrar marketing feeds. Anonymous history stays in your browser, and aggregate analytics record batch sizes and timings without the domain names themselves. Project content is excluded from analytics entirely. Signed-in history, shortlists and project domains are protected by account access controls and encrypted at rest.

Who else sees the domains I look up?

A lookup cannot happen without a DNS resolver and the registry receiving the name being queried. When a check runs on our servers, those providers see our server address rather than yours. Some Brand Check lookups are sent straight from your browser to the source, GitHub, the USPTO and the Certificate Transparency logs among them, which is faster and keeps the query out of our infrastructure, and in that case the provider sees your ordinary connection details.

Where is my data stored?

Signed-in history, shortlists and project domains are stored in the EU. Where a processor operates outside the European Economic Area, the transfer is covered by standard contractual clauses and, where applicable, certification under the EU to US Data Privacy Framework. The full list of processors and legal bases is in the privacy policy.

How long do you keep my data?

Accounts and saved research are kept until you delete them. Server access logs are purged after at most 14 days. Pseudonymous interest records are deleted on an 8-day rolling cycle. Consent receipts are kept for 180 days as evidence that a choice was recorded. Financial and tax records are kept for up to 10 years, because German commercial and tax law requires it.

How do I delete my account and everything in it?

From your account settings, in one action. It permanently removes your account, projects, project domains, notes, share links, history, shortlist, feedback, votes, usage counters and profile from the production database. Encrypted system backups are overwritten on a rolling 30-day schedule. Invoices are the one exception, because tax law requires them to be kept.

What cookies does the site use?

The essential ones only, unless you say otherwise. Those keep you signed in, remember your interface preferences, enforce usage limits and record your cookie choice itself. Two optional ones exist and stay off until you accept them: caching recent lookups in your browser to make repeat searches instant, and remembering interface state on the community pages. Cookie settings in the footer reopens the choice at any time, and rejecting is exactly as easy as accepting.

Still stuck?

Support reads every message. If you are looking for the longer explanations instead, each tool has a guide underneath it covering how it reaches an answer and where that answer stops being certain.
