The Blue dataset

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

Blue lives inside 2 datasets

Blue detection is part of Technologies (€159/mo) and All data (€599/mo). Buy either to filter the full 44-site list, or grab a free preview first.

Your Blue downloads

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

Format: JSONL (zstd) Dataset updated: 2026-08-18

API, columns & recipes → /account/api

Which websites are using Blue?

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

Open the Blue 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 Blue?

webatla detects Blue on 44 websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Blue?

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 Blue?

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

What else is in the Blue technology data?

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

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

Both. Every site running Blue 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 Blue?

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 Blue 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.
