About Koa

webatla tracks 9 live websites using Koa, 0.0% of every site we index. Download the full list of websites that use Koa as a daily JSONL export. Every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

Koa is a next-generation web framework for Node.js, created by the team behind Express. It uses async/await syntax and a middleware stack to make web application and API development cleaner and more expressive, with a significantly smaller footprint than Express.

Koa does not bundle any middleware by default, giving developers full control over the application stack. Its use of ES6 generators and later async functions eliminates callback hell and makes error handling more straightforward. Koa is widely used by developers building REST APIs and lightweight web services who want fine-grained control without the overhead of a larger framework.

The data in this record is provided by Identity Digital or the Registry Operator for informational purposes only, and accuracy is not guaranteed. This service is intended only for query-based access. You agree that you will use this data only for lawful purposes and that, under no circumstances will you use this data 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 data recipient's own existing customers; or (b) enable high volume, automated, electronic processes that send queries or data to the systems of Registry Operator, a Registrar, or Identity Digital except as reasonably necessary to register domain names or modify existing registrations. When using the Whois service, please consider the following: The Whois service is not a replacement for standard EPP commands to the SRS service. Whois is not considered authoritative for registered domain objects. The Whois service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the Whois 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 Whois service access. Abuse of the Whois 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 Whois 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. Access to this data provided by Identity Digital can be requested by submitting a request via the form found at https://www.identity.digital/about/policies/whois-layered-access/. The Registrar of Record identified in this output may have an RDDS service that can be queried for additional information on how to contact the Registrant, Admin, or Tech contact of the queried domain name. Identity Digital Inc. and Registry Operator reserve the right to modify these terms at any time. By submitting this query, you agree to abide by this policy."}	Domain is active

Which websites are using Koa?

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

Open the Koa 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 Koa?

webatla detects Koa on 9 websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Koa?

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 Koa?

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

What else is in the Koa technology data?

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

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

Both. Every site running Koa 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 Koa?

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 Koa 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.
