The data in this record is provided by Identity Digital or the Registry Operator for informational purposes only, and accuracy is not guaranteed. This service is intended only for query-based access. You agree that you will use this data only for lawful purposes and that, under no circumstances will you use this data 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 data recipient's own existing customers; or (b) enable high volume, automated, electronic processes that send queries or data to the systems of Registry Operator, a Registrar, or Identity Digital except as reasonably necessary to register domain names or modify existing registrations. When using the Whois service, please consider the following: The Whois service is not a replacement for standard EPP commands to the SRS service. Whois is not considered authoritative for registered domain objects. The Whois service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the Whois 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 Whois service access. Abuse of the Whois 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 Whois 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 provided by Identity Digital can be requested by submitting a request via the form found at https://www.identity.digital/about/policies/whois-layered-access/. The Registrar of Record identified in this output may have an RDDS service that can be queried for additional information on how to contact the Registrant, Admin, or Tech contact of the queried domain name.

About MUI

You can often recognise a MUI interface before a scanner does, because the buttons, the spacing and the form fields come out of the same specification on every site that uses the library. Consistency is the whole point of a component library, and consistency is also why its presence says something about the team behind the site.

MUI SAS has developed the library since 2014 and publishes the core under the MIT licence, written in JavaScript for React. Detection implies a React application rather than a page assembled by a template engine, and a team that chose speed of delivery over bespoke design. The pattern turns up across dashboards, admin consoles, internal tools and business software front ends. Marketing sites tend to want a look nobody else has, so they appear in this population less often.

Detection has a real limit here and it is worth stating plainly. Component libraries ship inside a compiled bundle, build tooling rewrites class names, and what survives into the delivered page is residue rather than a signature. Applications that renamed or fully compiled away the recognisable prefixes are invisible to a crawler. As of September 2026 we detect the library on 81,049 sites, which is a lower bound on a population that is genuinely hard to measure.

Compilation also explains a gap in the data. We publish no version breakdown for this library, because no dependable version marker reaches the page. Anyone who needs to know which release a particular application runs has to ask the application, not the crawl.

United States accounts for 55,423 of the detections and .com sits at the head of the suffix distribution, a shape that follows the geography of the React hiring market more than anything about the library itself.

The question the list answers is who has a React front end built on a shared design system. Recruiters and agencies sizing that market need the population, not a sample of it. Competing component libraries and design system vendors need it to know who is already committed and how deeply. Developer tool companies use it because a team that adopted one convention will adopt others. Checking a single domain by hand produces none of that, because the value sits entirely in the aggregate and in what else runs alongside.

Frequently asked questions

How many websites use MUI?

webatla detects MUI on 81K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using MUI?

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 MUI?

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

What else is in the MUI technology data?

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

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

Both. Every site running MUI 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 MUI?

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 MUI 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.
