VKUI is an open-source React component library developed by VK (VKontakte) for building user interfaces that match the visual style of the VK ecosystem, including VK Mini Apps and VK mobile applications. It provides a comprehensive set of accessible, mobile-optimized UI components following VK's design system.

VKUI is used primarily by developers building mini-applications within the VK platform or creating web apps that need to feel native to the VK environment. The library is publicly available on GitHub and is designed to support both mobile and desktop layouts. It is widely used in the Russian-speaking developer community and forms the foundation for many third-party VK Mini Apps.

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

What else is in the VKUI technology data?

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

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

Both. Every site running VKUI 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 VKUI?

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 VKUI 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.
