🔍How to Detect Akamai on a Website
There are several ways to identify whether a website is using Akamai.
Use a Technology Detection Tool Recommended
The fastest and most accurate method. TrueTechFinder analyzes HTML structure, script files, and DOM patterns to detect Akamai instantly.
Try TrueTechFinder freeCheck Page Source Code
Akamai uses proprietary HTTP header signatures that are highly distinctive and reliably identify its presence.
- Server: AkamaiGHost
- AkamaiNetStorage headers
- X-Check-Cacheable
- Akamai-GRN (Global Request Number)
- X-Akamai-Transformed
- *.akamaized.net CDN domains
- *.akamaihd.net (HD video delivery)
- *.akamai.net
- X-Cache: TCP_HIT from AkamaiNetStorage
- Pragma: akamai-x-check-cacheable
- True-Client-IP header
Use Browser Developer Tools
Open DevTools (F12), check the Network tab for Akamai-specific script filenames, request headers, and DOM attributes that reveal the underlying technology.
AkamaiGHost is one of the most recognizable server signatures on the internet and is a definitive indicator of Akamai CDN usage.
How to Detect Akamai Manually
Akamai is detected through distinctive HTTP response headers that it injects on all served responses:
Check Server Header
In DevTools > Network, click the main page request and look at Response Headers. Server: AkamaiGHost is a definitive Akamai identifier.
Look for Akamai-GRN Header
The Akamai Global Request Number (Akamai-GRN) is a unique request identifier present on all Akamai-served responses and confirms Akamai CDN usage.
Check Asset Domain Names
View page source and look for *.akamaized.net, *.akamaihd.net, or *.akamai.net asset URLs. These are Akamai's CDN delivery domains.
Use curl to Inspect Headers
Run 'curl -I https://example.com' to see response headers without a browser. AkamaiGHost in the Server header confirms Akamai delivery.
Akamai's proprietary header signatures (AkamaiGHost, Akamai-GRN, X-Check-Cacheable) are unique to Akamai and cannot be spoofed by other CDN providers.
