About Optimizely
Optimizely is a leading digital experience optimization platform offering A/B testing, multivariate testing, feature flagging, and personalization capabilities for websites and mobile applications. Founded in 2010 and headquartered in San Francisco, Optimizely enables product and marketing teams to experiment at scale and make data-driven decisions to improve conversion rates and user engagement.
The platform provides a visual editor for no-code experiment creation as well as a full-featured SDK for developer-driven testing. Optimizely's feature management capabilities allow engineering teams to safely roll out new features with gradual rollouts and kill switches. In 2021, Optimizely merged with Episerver to form a broader digital experience platform covering content management, commerce, and experimentation. It is used by enterprises across retail, media, technology, and financial services industries.

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.

Optimizely sites by TLD
The Optimizely dataset
Every site we've detected as running Optimizely — with version, hosting, country, TLD and traffic rank.
Optimizely lives inside 2 datasets
Optimizely detection is part of Technologies (€159/mo) and All data (€599/mo). Buy either to filter the full 26,512-site list — or grab a free preview first.
Which websites are using Optimizely?
webatla detects every site using Optimizely and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.
Open the Optimizely 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 Optimizely?
webatla detects Optimizely on 27K websites, refreshed daily — each with its domain, DNS, WHOIS, IP, country and ranking.
Can I download the list of websites using Optimizely?
Yes — as structured JSONL. Pay once for one month, no subscription; 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 Optimizely?
Buy the technology dataset, then download the complete list of domains we detect using Optimizely — re-exported every day.
What else is in the Optimizely technology data?
Each row places Optimizely next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.
