Wappalyzer alternative: look up the tech stack of any website by API

If you need to know what CMS, ecommerce platform, analytics or framework a list of websites uses, and you want to pay per site instead of a monthly plan, the Technology Detector does the lookup in bulk. It fetches each site over plain HTTP (no browser), matches it against 7,600+ technology fingerprints and returns JSON with versions, categories and top-level cms and ecommercePlatform fields.

Call it in one request

With your Apify API token in APIFY_TOKEN:

curl -X POST "https://api.apify.com/v2/acts/tenfoldfleet~tech-stack-detector/run-sync-get-dataset-items" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"domains":["shopify.com","wordpress.org","vercel.com"]}'

Pass as many domains as you like in one run; each one that loads is a result, and sites that fail to load are free.

Real output

We ran exactly that request on 13 Oct 2026 (Run ID: Mpe8wFviLaTnA2Zai). All three sites returned HTTP 200. Selected fields:

domain	technologyCount	cms	Detected, among others
wordpress.org	13	WordPress	WordPress 7.2, Nginx, PHP, MySQL, Gutenberg 24.1.0
vercel.com	27	none	Next.js, React, Vercel, Webpack, Stripe, Mixpanel
shopify.com	31	none	Shopify (ecommerce), Cloudflare (CDN), Stripe, Zendesk

The list includes services a site only links to or loads scripts for (for example Zendesk or OpenAI on a marketing site), so treat a technology as "present on the page" rather than "the core of the product". Results come from one page load per site, so technologies that appear only after login or deeper in the site are not seen.

Price per 1,000

$10 per 1,000 sites analyzed, with failed sites free. Checking the 3 sites above is 3 × $0.01 = $0.03 at that rate. The price is from the actor's Store listing on 13 Oct 2026; compare it with whatever you pay now before switching.

When this is the right tool

You have a list of domains (leads, competitors, customers) and want the CMS or platform for each, as CSV, JSON or Excel.
You want to call it from code, n8n, Make or an AI agent, and pay only for the sites you look up.
For one site at a time, the free checker is enough.
