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.

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.

About AB Tasty

An experimentation tag is one of the more informative things a website can carry, because nobody installs one by accident. AB Tasty is a A/B Testing and personalisation platform founded in 2013, sold by AB Tasty as a Proprietary product and delivered to the browser as JavaScript. As of September 2026 we detect it on 6,960 sites.

Running experiments requires three things a small site does not have: enough traffic for a result to mean anything, someone whose job is to interpret it, and a budget line that survives the quarter. A site carrying this tag has cleared all three. The platform is bought by marketing, product and growth teams at mid-market and enterprise organisations, and is used to run A/B and multivariate tests, to personalise content by audience segment, and increasingly to gate features behind flags for engineering teams as well.

The commercial reading follows directly. A list of sites running an experimentation platform is a list of organisations with a conversion optimisation function, which is a far narrower and more valuable population than a list of sites with traffic. Analytics vendors, personalisation and recommendation products, consent and customer data platforms, agencies selling optimisation retainers and competing testing tools all want the same set. Competitors want it for displacement, and complements want it because an organisation already paying for one optimisation tool has proven it buys this category at all.

Detection has a real limitation that deserves stating rather than burying. Client-side tags are found by reading the scripts a page loads, and modern deployments increasingly hide them. A tag delivered through a tag manager may fire only after consent is granted, an experiment running server-side or at the edge leaves nothing in the page at all, and a first-party proxy domain can disguise the vendor entirely. Every one of those patterns removes a genuine customer from our count, so the figure is a floor, and the gap is widest exactly where the most sophisticated buyers are.

A per-domain check answers whether a company you already care about runs this platform. The downloadable A/B Testing list answers what a lookup cannot: which organisations across a whole market run experimentation at all, how that set overlaps with the analytics and consent tooling on the same domains, and which sites added or dropped the tag between exports. Tag churn is a buying signal, and churn is only legible when both ends of the comparison are complete lists.
