About Kestrel

webatla tracks 2,510,186 live websites using Kestrel — 0.8% of every site we index. Download the full list of websites that using Kestrel technology as a daily JSONL export — every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

Kestrel is a cross-platform, high-performance web server built into ASP.NET Core, developed by Microsoft. It serves as the default HTTP server for ASP.NET Core applications and can operate either as an edge-facing server or behind a reverse proxy such as IIS, Nginx, or Apache. Kestrel is built on libuv (earlier versions) and .NET's own async I/O infrastructure for maximum throughput.

Unlike traditional full-featured web servers, Kestrel is intentionally lightweight and focused on raw HTTP performance, making it ideal for microservices and containerized workloads. It supports HTTP/1.1, HTTP/2, and HTTP/3, as well as HTTPS and Unix sockets. Kestrel's presence on a website indicates the site is likely running on ASP.NET Core, commonly in cloud-native or Windows-hosted deployments.

Which websites are using Kestrel?

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

Open the Kestrel 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 Kestrel?

webatla detects Kestrel on 2.5M websites, refreshed daily — each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Kestrel?

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 Kestrel?

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

What else is in the Kestrel technology data?

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

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

Both. Every site running Kestrel 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 Kestrel?

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 Kestrel 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.
