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. By submitting this query, you agree to abide by this policy."]},{"links":[{"rel":"glossary","href":"https://icann.org/epp","type":"application/rdap+json","value":"https://rdap.publicinterestregistry.org/rdap/domain/json-ld.org"}],"title":"Status Codes","description":["For more information on domain status codes, please visit https://icann.org/epp"]},{"links":[{"rel":"help","href":"https://icann.org/wicf","type":"application/rdap+json","value":"https://rdap.publicinterestregistry.org/rdap/domain/json-ld.org"}],"title":"RDDS Inaccuracy Complaint Form","description":["URL of the ICANN RDDS Inaccuracy Complaint Form: https://icann.org/wicf"]}],"entities":[{"roles":["registrant"],"events":[{"eventDate":"2025-09-15T08:41:22.23Z","eventAction":"last update of RDAP database"}],"remarks":[{"type":"object redacted due to authorization","title":"REDACTED","description":["Some of the data in this object has been removed."]}],"vcardArray":["vcard",[["version",{},"text","4.0"],["fn",{},"text",""],["org",{"type":"work"},"text","Digital Bazaar"],["adr",{"cc":"US"},"text",["","","","","VA","",""]]]],"objectClassName":"entity"},{"links":[{"rel":"self","href":"https://rdap.publicinterestregistry.org/rdap/entity/81","type":"application/rdap+json","value":"https://rdap.publicinterestregistry.org/rdap/entity/81"},{"rel":"about","href":"https://rdap.gandi.net","type":"application/rdap+json","value":"https://rdap.gandi.net"}],"roles":["registrar"],"handle":"81","entities":[{"roles":["abuse"],"handle":"ffba2eccf7e1438e9ddc9d520fe1bd1f-LROR","vcardArray":["vcard",[["version",{},"text","4.0"],["fn",{},"text","Arnaud Franquinet"],["tel",{"type":"voice"},"uri","tel:+33.170377661"],["email",{},"text","abuse@support.gandi.net"]]],"objectClassName":"entity"}],"publicIds":[{"type":"IANA Registrar ID","identifier":"81"}],"vcardArray":["vcard",[["version",{},"text","4.0"],["fn",{},"text","Gandi SAS"]]],"objectClassName":"entity"}],"redacted":[{"name":{"type":"Registry Domain ID"},"method":"removal","prePath":"$.handle","pathLang":"jsonpath"},{"name":{"type":"Registry Registrant ID"},"method":"removal","prePath":"$.entities[?(@.roles[0]=='registrant')].handle","pathLang":"jsonpath"},{"name":{"type":"Registrant Name"},"method":"emptyValue","pathLang":"jsonpath","postPath":"$.entities[?(@.roles[0]=='registrant')].vcardArray[1][?(@[0]=='fn')][3]"},{"name":{"type":"Registrant Street"},"method":"emptyValue","pathLang":"jsonpath","postPath":"$.entities[?(@.roles[0]=='registrant')].vcardArray[1][?(@[0]=='adr')][3][:3]"},{"name":{"type":"Registrant City"},"method":"emptyValue","pathLang":"jsonpath","postPath":"$.entities[?(@.roles[0]=='registrant')].vcardArray[1][?(@[0]=='adr')][3][3]"},{"name":{"type":"Registrant Postal Code"},"method":"emptyValue","pathLang":"jsonpath","postPath":"$.entities[?(@.roles[0]=='registrant')].vcardArray[1][?(@[0]=='adr')][3][5]"},{"name":{"type":"Registrant Phone"},"method":"removal","prePath":"$.entities[?(@.roles[0]=='registrant')].vcardArray[1][?(@[1].type=='voice')]","pathLang":"jsonpath"},{"name":{"type":"Registrant Email"},"method":"removal","prePath":"$.entities[?(@.roles[0]=='registrant')].vcardArray[1][?(@[0]=='email')]","pathLang":"jsonpath"},{"name":{"description":"Administrative Contact"},"method":"removal"},{"name":{"description":"Technical Contact"},"method":"removal"}],"publicIds":[{"type":"IANA Registrar ID","identifier":"81"}],"secureDNS":{"maxSigLife":1,"delegationSigned":false},"nameservers":[{"handle":"d693d214b7a048c49eff97de96233599-LROR","status":["associated"],"ldhName":"darwin.ns.cloudflare.com","unicodeName":"darwin.ns.cloudflare.com","objectClassName":"nameserver"},{"handle":"058052f736774535b17df88e3414872e-LROR","status":["associated"],"ldhName":"kristina.ns.cloudflare.com","unicodeName":"kristina.ns.cloudflare.com","objectClassName":"nameserver"}],"unicodeName":"json-ld.org","objectClassName":"domain","rdapConformance":["rdap_level_0","icann_rdap_response_profile_1","icann_rdap_technical_implementation_guide_1","redacted"]}}Domain is active

About Semantic UI

A front-end framework dates a website more reliably than it describes one. Semantic UI is a UI frameworks built around a specific bet, that class names should read like ordinary English so markup describes intent instead of layout, and the bet worked well enough that the framework spread through admin panels, dashboards, documentation sites and product marketing pages during the years when a component library resting on jQuery was the reasonable default.

Momentum then slowed. Work on the original project became intermittent and a community fork picked up active maintenance, which leaves the installed base in a distinctive position: working, widely deployed and no longer tracking anything upstream. Our version data shows the same story from the other side. We distinguish 15 releases and attach 2.4.2 to more detections than any other label, and a concentration of that kind is what appears when a project stops shipping and its users stop upgrading in step with it.

As of September 2026 we record Semantic UI on 20,899 sites. The framework is written in JavaScript, released under the MIT license and dates from 2013, which places its adoption curve before the build tooling and component model conventions that arrived afterwards and reshaped how interfaces get assembled.

A frozen dependency is a commercial signal as much as a technical one. Sites in this population are candidates for a rebuild, which is what agencies, design system vendors and contract developers spend money to find. The same population is worth a security review, because a static component layer normally sits on an equally static set of scripts beneath it, and nothing in the stack is being refreshed by anybody's release cycle. Tooling vendors and framework maintainers read the list for a third reason, as a measure of how much production code still leans on a project whose upstream has gone quiet.

Detection is markup based and therefore partial. A build step that renames or prunes class names, or a theme layer that wraps the framework in something of its own, can hide it completely, and version strings surface only where an unmodified distribution file is served, so a share of matches arrive with no version attached. The totals are a lower bound rather than a count of the framework's real footprint.

What a download adds over a per-domain check is the ability to hold the population at once and cut it: by release line, by country, by domain suffix, or by the other technologies sitting alongside on the same pages. Confirming that one site uses an aging framework takes a browser and a minute. Sizing the market of sites that will need to leave it, and getting the domain list that makes the work actionable, takes the whole set.
