About Kasada
webatla tracks 1,750 live websites using Kasada — 0.0% of every site we index. Download the full list of websites that using Kasada technology as a daily JSONL export — every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.
Kasada is a bot mitigation and anti-automation security service made by the Australian company Kasada, which was founded in 2015 by Sam Crowther in Sydney. It defends websites, mobile apps, and APIs from automated threats such as credential stuffing, account takeover, content scraping, and fake account creation by fingerprinting incoming traffic and issuing invisible cryptographic challenges rather than visible CAPTCHAs. The service embeds client-side JavaScript on the sites that deploy it, which makes its presence detectable, and its challenge flow is commonly associated with an initial HTTP 429 response that resolves once the challenge is passed.

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.

The Kasada dataset
Every site we've detected as running Kasada — with version, hosting, country, TLD and traffic rank.
Kasada lives inside 2 datasets
Kasada detection is part of Technologies (€159/mo) and All data (€599/mo). Buy either to filter the full 1,750-site list — or grab a free preview first.
Which websites are using Kasada?
webatla detects every site using Kasada and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.
Open the Kasada 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 Kasada?
webatla detects Kasada on 2K websites, refreshed daily — each with its domain, DNS, WHOIS, IP, country and ranking.
Can I download the list of websites using Kasada?
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 Kasada?
Buy the technology dataset, then download the complete list of domains we detect using Kasada — re-exported every day.
What else is in the Kasada technology data?
Each row places Kasada next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.
Can I download just the sites using Kasada, or the whole database?
Both. Every site running Kasada 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 Kasada?
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 Kasada 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.
