How this service works
Does a website use Next.js? Fetches the page (homepage for a bare domain) and matches Next.js's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (framework). 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 Next.js, along with the matched evidence snippet (e.g. a specific HTML chunk or response header value) and a category label (framework). This lets agents programmatically branch on adoption status or surface the proof to a human.
Example use cases
Sales prospecting for Next.js shops
“I'm targeting companies that use Next.js for my migration consulting service — can you check if acme.com uses Next.js so I know whether to reach out?”
Competitor tech stack research
“I want to know if my competitor vercel.com is running Next.js — check their homepage and show me the evidence snippet.”
Migration planning audit
“Before we start the migration project, can you verify whether legacyshop.com is already on Next.js or still on something else?”

Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/nextjs?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single, cheap ($0.01) per-domain check specifically for Next.js detection with evidence. Prefer it over broader tech-stack APIs when you only care about the Next.js signal and want to minimize cost per lookup. It is ideal for bulk prospecting pipelines where each domain is checked individually, or for one-off spot checks during sales or migration workflows.
Side effects
- Domain unreachable or returns a non-200 response — detection cannot proceed
- Site uses heavy client-side rendering so fingerprints are not present in server-rendered HTML
- Next.js fingerprints are obscured by a CDN or reverse proxy stripping headers
- Rate limiting or blocking by the target site prevents fetching the page
- Ambiguous result if the site partially proxies Next.js assets but isn't itself a Next.js app
