About Yaws

webatla tracks 151 live websites using Yaws, 0.0% of every site we index. Download the full list of websites that use Yaws as a daily JSONL export. Every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

Yaws (Yet Another Web Server) is a high-performance, open-source web server written in Erlang, designed to handle large numbers of concurrent connections with low memory overhead. Its architecture leverages Erlang's concurrency model to serve thousands of simultaneous requests efficiently.

Yaws is particularly well-suited for dynamic web applications and REST APIs that require high concurrency, and it supports WebSockets, SSL/TLS, and server-side Erlang scripting. While not as widely deployed as Apache or Nginx, Yaws has a dedicated following among Erlang developers and is used in telecommunications, financial, and real-time web applications where Erlang's fault-tolerance characteristics are valued.

Which websites are using Yaws?

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

Open the Yaws 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 Yaws?

webatla detects Yaws on 151 websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Yaws?

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 Yaws?

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

What else is in the Yaws technology data?

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

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

Both. Every site running Yaws 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 Yaws?

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 Yaws 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.
