Netlify Detector
Paste any URL and instantly see whether the site is built with Netlify — with the matched evidence.
We do not store the URL you audit. Want the full audit (performance / images / SEO / accessibility + real-browser speed test)? → run the full audit
Why check this
Confirm the platform first: Hosting & CDN decides what can be changed and whether it is worth it.
What this is
Netlify is a front-end hosting and edge platform used for Jamstack sites and preview branches. Confirming `x-nf-request-id`, `server: Netlify` or `/.netlify/` shows whether redirects, edge functions or cache headers are misconfigured. Redirect rules and edge functions are where latency surprises usually hide.
How to tell from a public page
- [Netlify] Response headers include `x-nf-request-id`.
- [Netlify] The `server` header names Netlify.
- [Netlify] Paths expose `/.netlify/` function or identity endpoints.
- [Netlify] Hostnames use a `netlify.app` preview domain.
How to read the result
Confirm when platform headers or `/.netlify/` reproduce; a footer deploy badge can be faked without header evidence. Absence can mean another CDN sits in front of the custom domain. Documentation sample responses sometimes include the distinctive headers. After a hit, verify `_headers` and redirect loops.
What to do next
Tighten cache headers, review edge-function latency, and cross-check historically common Gatsby front ends — open Gatsby detector. Full audits return via run the full performance / images / SEO / accessibility audit on the home page. Prefer explicit `_headers` over hoping the CDN guesses correctly.

FAQ
How is Netlify detected?
From structural signatures in the public HTML and response headers (domains, paths, attributes, scripts). Every verdict lists how many times each pattern matched — nothing is guessed.
Can the result be wrong?
If only a bare brand keyword matches without structural evidence, we label it \u201clikely\u201d instead of \u201cconfirmed\u201d — we would rather under-report than cry wolf.
Do you save the URLs I check?
No. The audit runs inside the request and the URL you paste is not written to storage. There are no third-party tracking scripts on the page either, so no log of who checked what exists. Copy the result yourself if you want a record.
Can a website hide what it is built with?
Partly, but rarely completely. The HTML sent to your browser, the response headers, script paths and asset structure have to be exposed to work, so there is always something readable. Server-side code, build config and private APIs stay invisible. That is why this tool reports the evidence it found rather than claiming a full picture. No match does not mean the technology is absent.
