Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources.

Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above.

About core-js
Almost nobody decides to install core-js. As a modular polyfill library it arrives inside a JavaScript bundle, pulled in as a transitive dependency of a transpiler preset or a framework starter, and the person responsible for the website will often never have heard of it. Anyone scanning the web for core-js is therefore not measuring adoption in the usual sense of a preference or a purchase. What the scan measures is the residue of build pipelines, and once you accept that framing the data becomes more useful rather than less.
A polyfill exists so that newer language features keep working in older engines. A site shipping core-js is a site whose toolchain was configured, at some point, to support browsers its visitors may long since have abandoned, and such configuration is rarely revisited. Front end weight, page speed budgets and the slow decay of unmaintained sites all follow from the same fact. First published in 2014 and MIT licensed, the library has outlasted several generations of browser support policy, which is why a bundle served today can still carry compatibility shims for engines almost nobody runs.
Scale gives the pattern its shape. As of September 2026 we detect core-js on 18,580,259 sites, with 8,024,930 of those in United States and the set skewing heavily toward .com. Geography here says little about where the library is written and a lot about where commercial, framework heavy web development is concentrated, because the code travels with the tooling that agencies and product teams standardise on.
Detection is inferential and it undercounts. Fingerprints survive minification unevenly, bundlers rename and tree shake, and a build that inlines only a handful of polyfills may leave nothing recognisable behind at all. Our record for this entry also carries no usable version breakdown, so the dataset can tell you where the library is present but not which release is shipping. Anyone planning work that depends on a specific release needs to treat the list as a candidate set and confirm on the sites that matter.
The people who ask us for this list fall into a few groups. Security and supply chain teams want the reach of a widely trusted package with a small maintainer base, because reach is what makes a dependency worth attacking. Performance vendors want sites that ship legacy compatibility code they no longer need. Framework and browser maintainers want evidence before dropping support for something old. Checking a single domain answers none of those questions, and checking a single domain is easy anyway, since a browser developer panel will do it in moments.
What a downloadable list adds is the inverse query. Instead of asking what a known site runs, you ask which sites in a country, under a suffix, on a given ecommerce platform or behind a given delivery network also carry this dependency, and you get the whole population back as rows you can join against your own account data. Rebuilding that from per domain lookups means crawling the registered namespace yourself, which is the work we have already done.
Frequently asked questions
How many websites use core-js?
webatla detects core-js on 18.6M websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.
Can I download the list of websites using core-js?
Yes, as structured JSONL. Grab a free sample first.
What's included for each site, and how fresh is it?
Domain, DNS, RDAP/WHOIS, the full technology stack, IP & country, PageRank and Harmonic, re-detected and re-exported daily.
How do I find the websites using core-js?
Buy the technology dataset, then download the complete list of domains we detect using core-js, re-exported every day.
What else is in the core-js technology data?
Each row places core-js next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.
Can I download just the sites using core-js, or the whole database?
Both. Every site running core-js comes in the Technologies dataset, one downloadable file. Or buy All data for the entire database: technologies plus identity, ranking, DNS and RDAP/WHOIS for every domain, combined in one file. Daily fresh export.
How do I download the list of websites using core-js?
Three steps: (1) grab the free 10,000-row sample to inspect the schema, (2) buy the Technologies dataset, (3) download the full list of every domain we detect running core-js as a JSON Lines file. It is re-exported daily, so you can re-download the freshest list any time inside your access window. Each row carries the domain plus DNS, WHOIS, IP, hosting country and rank.
