About K2

webatla tracks 6,271 live websites using K2, 0.0% of every site we index. Download the full list of websites that use K2 as a daily JSONL export. Every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

K2 is a powerful content construction kit extension for Joomla, the open-source CMS. It extends Joomla's native content management capabilities by adding structured content types, custom fields, tags, and user profiles, enabling more complex editorial and community-driven websites.

Developed by JoomlaWorks, K2 has been widely used by news sites, blogs, and content-heavy portals built on Joomla. It offers fine-grained access control, commenting systems, and a rich item management interface. While Joomla's built-in capabilities have expanded over time, K2 remains popular among sites that rely on its established feature set and extensive template ecosystem.

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 K2?

webatla detects every site using K2 and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.

Open the K2 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 K2?

webatla detects K2 on 6K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using K2?

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 K2?

Buy the technology dataset, then download the complete list of domains we detect using K2, re-exported every day.

What else is in the K2 technology data?

Each row places K2 next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.

Can I download just the sites using K2, or the whole database?

Both. Every site running K2 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 K2?

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 K2 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.
