About core-js

webatla tracks 18,626,323 live websites using core-js, 6.0% of every site we index. Download the full list of websites that use core-js as a daily JSONL export. Every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

core-js is a modular standard library for JavaScript that provides polyfills for ECMAScript features, including newer syntax and built-in objects not yet supported in all browsers. It is one of the most widely downloaded packages in the JavaScript ecosystem and is commonly used under the hood by Babel and other transpilation tools.

Maintained primarily by Denis Pushkarev, core-js enables developers to use modern JavaScript features while maintaining compatibility with older browsers and environments. It is included as a dependency in countless frameworks, build tools, and applications, making it one of the most ubiquitous JavaScript libraries on the web, even when not explicitly listed as a direct dependency.

Public Interest Registry does not guarantee its accuracy. 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. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above. Access to non-public data may be provided, upon request, where it can be reasonably confirmed that the requester holds a specific legitimate interest and a proper legal basis for accessing the withheld data. Access to this data can be requested by submitting a request to WHOISrequest@pir.org. Public Interest Registry Inc. reserves the right to modify these terms at any time.

Which websites are using core-js?

webatla detects every site using core-js and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.

Open the core-js technology dataset to break adoption down by country and TLD, compare it with a competing technology, and track new domains over time.

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.
