Bulk website status checker: live, redirecting or parked, for up to 500 domains
A bulk website status checker loads the home page of many domains at once and reports what answers. Paste up to 100 domains, or 500 after a Google sign-in, and each shows its HTTP status, where it redirects, its page title, and whether it looks parked or for sale, with the signal behind that label. Download the results as CSV.
Sample result
acme.example is live. old-acme.example looks for sale: it redirects to a domain marketplace.
- Domain
- old-acme.example
- Status
- 302, then 200
- Lands on
- marketplace.example
What this means for you
Drop leads on parked or dead domains before you verify and send to the rest.
- HTTP status and every redirect hop
- Parked and for-sale signals, each one named
- 100 domains a run, 500 when signed in
- No cookies; private addresses never fetched

How do I check the status of many websites at once?
- Paste up to 100 domains, one per line (500 when signed in with Google), or email addresses or website URLs; the domain is taken from each. You can also upload a CSV.
- Press Check websites. Each home page is requested once over HTTPS, then HTTP if HTTPS doesn't answer, ten domains at a time.
- Read each row: Live, Redirects (with the target), HTTP error, No answer or Doesn't resolve, plus a Looks parked or Looks for sale label where we saw a signal.
- Filter to parked or redirecting domains, and download the CSV with status, final URL, title and the parking signals.
Example
- You enter
- Two domains pasted one per line:
acme.exampleandold-acme.example. - You get
acme.exampleis Live.old-acme.exampleRedirects: a 302 tomarketplace.example, which answers 200 with a title saying the name is for sale, so it is labelled Looks for sale and the signal is quoted. It has no MX record.- Limits
- Up to 100 domains a run without an account and 500 when signed in with Google. Only the home page is requested, once, and private or reserved addresses are never fetched.
How do I check if many websites are live at once?
Paste the domains and press Check websites. For each one the checker looks up its DNS records, then requests the home page once, following up to five redirects, and records every status code on the way. RFC 9110 defines the codes: 2xx means the page loaded, 3xx a redirect, 4xx a client error such as 404, and 5xx a server error.
It checks 100 domains a run without an account and 500 when you sign in with Google. The request identifies itself honestly as SimpleVerifier, sends no cookies, and reads at most 128 KB of each page.
How does it tell a domain is parked or for sale?
From three kinds of signal, and each row names the one it saw. Nameservers run by parking services such as Sedo, Bodis and ParkingCrew mean the domain is set up to show a parking page. A redirect to a domain marketplace such as Dan.com, Afternic, Sedo or HugeDomains usually means it's listed for sale. And phrases on the page, such as "this domain may be for sale" or "parked free", or scripts loaded from a parking service, point the same way.
These are heuristics, so the label is "looks parked" or "looks for sale", never a certainty. A parked page can sit on a domain that isn't for sale, a for-sale domain can show a normal site, and a page can mention those phrases for other reasons. The registrar or marketplace is the only source of truth on whether a name can be bought.
Why does a site show an error but load in my browser?
Some sites refuse requests that don't come from a browser, and answer 403 Forbidden or 429 Too Many Requests to anything automated, which includes this checker. Others block requests from cloud servers, or only answer visitors from certain countries.
A timeout can be a slow server or a firewall that drops unknown traffic. If a domain matters, open it in a browser to confirm. Domains that resolve only to private or reserved addresses are never fetched, by design.
What can I use a bulk website status check for?
Cleaning a lead list: a company whose domain is parked, for sale or doesn't resolve has probably closed or moved, and email to it is likely to bounce. Auditing a domain portfolio: see which domains redirect where they should and which have lapsed into parking. Checking a migration: confirm old domains redirect to the new site.
For lead lists, the next step after removing dead domains is the addresses themselves. Our bulk DNS lookup shows which domains have MX records, and verification checks each mailbox before you send.
How is this different from opening each site in a browser?
| This checker | A browser | |
|---|---|---|
| Domains per run | 100, or 500 signed in | One tab at a time |
| Status codes and redirect hops | Every hop listed | Hidden unless you open developer tools |
| Parked and for-sale signals | Named per domain | You judge the page yourself |
| JavaScript-only sites | Not rendered | Rendered |
Who uses this tool, and for what?
- Cold emailers
- Drop leads whose company domain is parked, for sale or doesn't resolve before verifying and sending.
- Domain investors
- See which names in a list are parked, listed on a marketplace or running a real site.
- Agencies
- Check that every client domain loads and redirects where it should after a site migration.
- Sales operations
- Flag accounts in a CRM export whose website has gone dark or now redirects to another company.
What can’t this tool tell you?
- "Looks parked" and "looks for sale" are heuristics. They name the signal seen and can be wrong either way.
- Sites that block automated or cloud traffic can show 403, 429 or a timeout while loading fine in a browser.
- Only the home page is requested, once. It doesn't render JavaScript, so a site built entirely in JavaScript can show a near-empty title.
- Domains that resolve only to private or reserved addresses aren't fetched.
- Up to 100 domains a run without an account, 500 signed in.
Common questions
- How do I check if a list of websites is up?
- Paste the domains into a bulk website status checker like this one. It requests each home page and shows the HTTP status, where it redirects and whether it answered at all, with a CSV of the results.
- Is this bulk website checker free?
- Yes. It's a free tool: up to 100 domains a run with no account, and up to 500 a run when you sign in with Google, with no card.
- How can I tell if a domain is parked?
- Look at its nameservers, where it redirects and what the page says. Parking services use their own nameservers, for-sale domains often redirect to a marketplace, and parking pages say things like "this domain may be for sale". This checker reads all three and names the signal it found.
- Does looks for sale mean I can buy the domain?
- Not necessarily. It means we saw a for-sale signal, such as a redirect to a marketplace. The marketplace or registrar confirms whether it's for sale and at what price.
- Why does a website show 403 here?
- Many sites refuse automated requests. A 403 or 429 here doesn't mean the site is down; open it in a browser to check.
- Does it follow redirects?
- Yes, up to five, and it lists every hop. Redirects to other ports, other protocols or private addresses are not followed.
Sources
A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
- Upload the cleaned file as it is: CSVs up to 100,000 rows
- A real SMTP mailbox check on every row, with catch-all detection
- Small list? $9 one-time covers 2,500 emails, no subscription
One plan, cancel anytime, no contract. Sign in with Google and your first 100 email checks are free, no card. The free tools stay free either way.
