About Modernizr

webatla tracks 2,849,166 live websites using Modernizr — 0.9% of every site we index. Download the full list of websites that using Modernizr technology as a daily JSONL export — every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

Modernizr is an open-source JavaScript library that detects HTML5 and CSS3 feature support in the user's browser, enabling developers to write conditional JavaScript and CSS to handle varying levels of browser capability. Rather than relying on browser version detection, Modernizr tests for specific features, allowing for more reliable progressive enhancement and graceful degradation.

Launched in 2009, Modernizr became a foundational front-end development tool during the era of widespread browser fragmentation. Though modern browser support has improved significantly, Modernizr remains in use on millions of sites that require backward compatibility. It integrates easily with build tools and supports a customizable build to include only the feature detects needed.

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.

The Modernizr dataset

Every site we've detected as running Modernizr — with version, hosting, country, TLD and traffic rank.

Modernizr lives inside 2 datasets

Modernizr detection is part of Technologies (€159/mo) and All data (€599/mo). Buy either to filter the full 2,849,166-site list — or grab a free preview first.

Your Modernizr downloads

The datasets you own, sliced to Modernizr. Every button streams the latest daily export directly.

Format: JSONL (zstd) Dataset updated: 2026-07-28

API, columns & recipes → /account/api

Which websites are using Modernizr?

webatla detects every site using Modernizr and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.

Open the Modernizr 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 Modernizr?

webatla detects Modernizr on 2.8M websites, refreshed daily — each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Modernizr?

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 Modernizr?

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

What else is in the Modernizr technology data?

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

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

Both. Every site running Modernizr 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 Modernizr?

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 Modernizr 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.

Get the full list of websites using Modernizr

Pick the dataset that covers what you need. Each one includes Modernizr and downloads as JSONL, rebuilt daily.
