Cache checker
Inspect CDN and browser cache signals for any public URL.
What this checks
The request inspects response headers to identify CDN behavior, browser caching, and likely origin infrastructure.
- • Akamai:
server-timing: ak_p - • Vercel:
x-vercel-cache - • CloudFront:

Results are a diagnostic snapshot, not a guarantee of every cache layer in the request path.
How to read the results
- •HIT usually means the CDN served a cached response.
- •MISS means the CDN contacted the origin for this request.
- •A rising cache age suggests the same cached object is being reused.
