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.

About OpenLayers

A map on a page is a commercial decision before it is a technical one. Sites that only need to show an address use whatever their CMS bundles and never think about it again. Sites that reach for OpenLayers are normally doing something harder and have someone on hand who can build it.

OpenLayers is a JavaScript mapping library published under the BSD licence and in continuous development since 2006. The library draws raster and vector tiles from many different sources, handles coordinate systems and projections properly rather than assuming one global scheme, and exposes control over rendering and interaction that hosted map widgets deliberately hide. Requirements of that kind cluster in planning portals, utilities, environmental monitoring, cadastral and land registry viewers, transport operators, universities and research groups.

Presence of OpenLayers is therefore a reasonable proxy for an in-house or contracted development team and for a project with genuine geospatial requirements. The licence matters as much as the capability. A permissively licensed library carries no per-view billing and no vendor account, which is why it appears so often in public sector and academic work where a metered commercial mapping API is awkward to procure and awkward to budget for over the life of a system.

For a researcher the interesting question is rarely whether one site uses the library. The questions worth a dataset are which sectors and which national domains have standardised on open mapping stacks, which organisations pair OpenLayers with a particular tile server, CMS or backend, and how that population compares with sites built on commercial map platforms. As of September 2026 we record OpenLayers on 11,878 sites, which is enough to segment by country, by domain suffix and by the rest of a site's stack rather than merely to state a total.

Undercounting is the honest caveat. OpenLayers ships as a module that is normally bundled and minified together with the rest of an application, and once identifiers are mangled and files are concatenated there may be nothing distinctive left to match. Detection works best where the library is loaded as a recognisable file or leaves its own class names and DOM structure intact. The visible population therefore skews toward simpler integrations and older pages, and the real installed base is larger than any figure we can defend.

Frequently asked questions

How many websites use OpenLayers?

webatla detects OpenLayers on 12K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using OpenLayers?

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 OpenLayers?

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

What else is in the OpenLayers technology data?

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

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

Both. Every site running OpenLayers 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 OpenLayers?

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 OpenLayers 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.
