About Modernizr
webatla tracks 2,558,321 live websites using Modernizr, 0.8% of every site we index. Download the full list of websites that use Modernizr 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.

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 2,558,321-site list, or grab a free preview first.
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 2.6M 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.
