About ZK

webatla tracks 306 live websites using ZK, 0.0% of every site we index. Download the full list of websites that use ZK as a daily JSONL export. Every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

ZK is an open-source Ajax web application framework for building enterprise Java web applications with rich user interfaces. Developed by Potix Corporation, ZK enables developers to create interactive web UIs using a component-based model in Java and XML, without requiring extensive JavaScript knowledge. The framework follows a server-centric architecture where UI logic runs on the server.

ZK provides hundreds of ready-made UI components, supports event-driven programming, and includes features for data binding, responsive design, and mobile support. It is available in both an open-source Community Edition and a commercial Enterprise Edition with additional components and support. ZK is commonly used in enterprise applications, business intelligence dashboards, and internal tools.

Which websites are using ZK?

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

Open the ZK 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 ZK?

webatla detects ZK on 306 websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using ZK?

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 ZK?

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

What else is in the ZK technology data?

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

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

Both. Every site running ZK 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 ZK?

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 ZK 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.
