Detect a website's tech stack in PHP

One request to the SiteIntel API returns the detected technologies, metadata, and contact data for any URL. Here is a complete, working PHP example — swap in your RapidAPI key.

$api = "https://siteintel.duckdns.org/v1/analyze?url=" . urlencode("https://stripe.com");
$ctx = stream_context_create(["http" => ["header" => "X-RapidAPI-Key: YOUR_KEY"]]);
$data = json_decode(file_get_contents($api, false, $ctx), true);
print_r($data["detected_tech"]);

The response includes detected_tech, title, description, Open Graph fields, favicon, social_profiles, and emails.

FAQ

How do I detect a website's tech stack in PHP?

Send a GET request to https://siteintel.duckdns.org/v1/analyze?url=<site> with your RapidAPI key in the X-RapidAPI-Key header. SiteIntel returns a detected_tech array (CMS, frameworks, analytics, payment providers, CDN) plus metadata, social profiles, and public emails.

What does the API return besides the tech stack?

Each /v1/analyze response also includes the site title and description, Open Graph metadata, favicon, social profiles, and any public emails published on the page — all in one JSON response.
