CDN Detector
Identify which CDN is serving a website. Supports Akamai, Cloudflare, Vercel, CloudFront, Fastly, Netlify, and more.
How this tool works
This tool runs on Cloudflare Workers, so Cloudflare headers may appear in the response. However, we correctly identify the actual CDN by checking for provider-specific headers first:
- • Akamai:
server-timing: ak_p - • Vercel:
x-vercel-cache - • CloudFront:
x-amz-cf-id - • Fastly:
x-served-by - • Netlify:
x-nf-request-id
The "Provider" field shows the detected CDN. Use the curl command below to verify from your own location.
How it works
- •We fetch the URL headers and analyze cache-related headers like cf-cache-status, x-vercel-cache, x-cache, server-timing, etc.
- •CDN detection works for Cloudflare, Akamai, Vercel, CloudFront, Fastly, Netlify, and others with standard headers.
- •Browser cacheability is determined by cache-control directives.
- •Note: Results are fetched through our worker which may add some headers. Use the curl command above to verify from your location.
