Free Online CDN Finder
Instantly check if a website is using a Content Delivery Network (CDN) and identify the provider.
What is a CDN?
A Content Delivery Network (CDN) is a group of servers distributed around the world that work together to provide fast delivery of internet content. They store cached copies of a website's assets (like images, videos, and code) in multiple locations.
When you visit a website that uses a CDN, you connect to the server closest to you, which dramatically reduces loading times and improves website performance and security. Our tool helps you see if a site is taking advantage of this technology.

Find CDN NowFrequently Asked Questions
How accurate is the CDN detection?
By checking both headers and DNS records against a database of popular CDNs, our tool is highly accurate. However, some CDNs can be configured to hide their identity, making them difficult to detect.
What does it mean if no CDN is detected?
It typically means the website is hosted on a single server (or cluster) and does not use a distributed network to deliver content. This can result in slower load times for visitors far from the server.
Why is the IP address shown a CDN's IP?
When a site uses a CDN, its domain name points to the CDN's servers, not its original hosting server. The IP address you see is the "edge" server from the CDN that is responding to our request.
