How this service works
Does a website use Fastly? Fetches the page (homepage for a bare domain) and matches Fastly's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (CDN). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no boolean indicating whether the site uses Fastly, along with an evidence snippet (the matching HTML content or response header value that triggered the fingerprint match) and the technology category label 'CDN'.
Example use cases
Competitor CDN stack research
“I'm putting together a technographic profile of our top 10 competitors — can you check whether shopify.com uses Fastly CDN and show me the evidence snippet?”
Pre-migration CDN audit
“Before we pitch our CDN migration service to cloudflare.com, can you check if they're currently using Fastly so we know whether they're already a Fastly customer?”
Sales prospecting for Fastly alternatives
“I'm building a list of companies to target for our CDN product — can you check if twitch.tv uses Fastly so I know whether they'd be a good prospect?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/fastly?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-domain technographic check specifically for Fastly CDN usage — ideal for sales prospecting, competitor stack analysis, or migration planning workflows. Prefer the bulk sibling endpoint for checking multiple domains at once. Choose this over generic HTTP header tools when you want pre-built Fastly-specific fingerprinting logic applied automatically.
Side effects
- Domain is unreachable or returns a non-200 response, leading to an inconclusive result
- Site uses bot-detection or blocks automated fetches, causing false negatives
- Fastly fingerprint may not be present on internal pages only exposed behind auth
- Paywalled or login-gated homepages may not expose CDN headers or scripts
- Network timeouts if the target domain is slow to respond
