npmjs.com
npmjs.com blocks automated analysis, answering with Cloudflare interstitial instead of its homepage. Its certificate, DNS and registration records are still readable and are reported below.
This site blocks automated analysis. It answered our request with Cloudflare interstitial rather than its homepage, so nothing below is derived from its actual content — doing so would describe the bot wall, not the site. The certificate and robots.txt data are still accurate, because those are served to everyone.

When was npmjs.com registered?

The registrar of record is MarkMonitor Inc..
Registration runs until 19 March 2031.
The domain carries 3 registry locks, which blocks unauthorised transfer or deletion.
| Registered | 19 March 2010 |
|---|---|
| Expires | 19 March 2031 |
| Registrar | MarkMonitor Inc. |
| Registry status | client delete prohibited, client transfer prohibited, client update prohibited |
Where is npmjs.com hosted?
The first address resolves to infrastructure in Toronto, Canada.
The network is operated by Cloudflare, Inc. (AS13335 Cloudflare, Inc.).
Hosting location describes where the responding server sits, not where the business is. A CDN will report its nearest edge rather than the origin.
What is npmjs.com running on?
No platform, framework or analytics fingerprints were found in the homepage markup of npmjs.com. That usually means hand-written HTML, an uncommon stack, or a page assembled entirely at the edge.
No recognisable platform, framework or analytics fingerprints were found in the homepage markup.
How does the homepage respond?
The server answered with HTTP 403 over HTTPS.
At 108ms to first byte this response is fast for a homepage measured from a single European location.
At 6KB the HTML is unusually small, which typically means the page builds itself client-side after load.
The HTML is compressed with gzip.
| Server header | cloudflare |
|---|---|
| Compression | gzip |
| Page size | 5,639 bytes |
| Declared language | not declared |
| Mobile viewport | not declared |
What does the homepage say about itself?
The homepage has no title element at all, which leaves search engines to invent one from the page content.
There is no meta description, so the snippet shown in search results is assembled by the search engine from whatever text it considers relevant.
No H1 heading was found, so the page offers no single top-level statement of what it is.
No viewport meta tag is declared, so mobile browsers will render the page at desktop width and scale it down.
The html element declares no lang attribute, which removes a signal both screen readers and translation tools rely on.
| Title | — none — (0 chars) |
|---|---|
| Meta description | — none — (0 chars) |
| H1 | — none — (0 on the page) |
| Canonical | not set |
| Open Graph title | not set |
| Headings / images | 0 H2s, 0 images (0 without alt text) |
Is npmjs.com served over a valid certificate?
The HTTPS certificate is issued by Google Trust Services and is valid until 2026-12-10, which is 66 days from the date of this check. It covers 3 hostnames.
- npmjs.com
- *.internal.npmjs.com
- *.npmjs.com
The certificate has 66 days left to run.
Which security headers does it set?
None of the 6 headers checked are set. That is the default state of most servers rather than evidence of a problem, but it means the browser is given no instructions it could otherwise act on.
| Header | Set | Value |
|---|
How is DNS configured for npmjs.com?

| TXT records | 8 |
npmjs.com resolves to 4 addresses, which indicates load balancing or a CDN rather than a single origin server.
Mail is handled by 5 exchangers.
An SPF record is published, giving receiving servers a rule for which hosts may send as this domain.
Reverse DNS resolves to 104.17.135.117, 104.17.134.117, which usually names the hosting provider.
Can npmjs.com be spoofed in email?
DMARC is set to quarantine, so mail failing authentication is sent to spam rather than the inbox.
CAA records restrict certificate issuance to 6 named authorities (issuewild ssl.com, issue comodoca.com, issue digicert.com; cansignhttpexchanges=yes, issue letsencrypt.org), so no other CA should be able to issue for this domain.
The zone is not DNSSEC-signed. That is still the norm for most domains, but it means DNS answers cannot be cryptographically verified.
What does robots.txt allow?
No robots.txt was served. Crawlers treat a missing file as permission to crawl everything, so this is an open crawl policy by default rather than a blocked one.
What structured data does the homepage publish?
No JSON-LD or microdata was found on the homepage.
Frequently asked questions
Does npmjs.com allow AI crawlers?
No robots.txt is served, so nothing is disallowed and AI crawlers are free to read the site.
Where does this data come from?
Every figure was measured by our own server on 4 October 2026: DNS lookups, one HTTPS request to the homepage, a TLS handshake and a request for robots.txt. No third-party SEO API is involved.
Is any of this traffic or authority data?
No. Traffic, authority and ranking figures cannot be measured by inspecting a domain, only modelled. Everything here is a direct observation.
I own npmjs.com and want this page removed.
Email hello@quikconsolecom.net from an address at the domain and the report will be taken down. It only ever shows what the domain already serves publicly.
