What is Tech Stack Detector?

Detects the technologies a website runs from its homepage: CMS, ecommerce platform, analytics and tag managers, JavaScript frameworks, hosting and CDN, payment processors, marketing automation, live chat and thousands more. It returns each technology with its category, version when the site reveals it, and a confidence score, plus one column per common category so a list is easy to filter. Sites where nothing is found are skipped and not charged. Built for technographic lead lists, sales qualification and competitive research.

• Every technology found. Name, category, version when the site reveals it, and a confidence score, across thousands of known technologies.
• The columns you filter on. CMS, ecommerce platform, analytics, JavaScript framework, hosting and CDN, payments, marketing automation and live chat, each as its own field.
• Hosting and infrastructure. CDNs, cloud platforms and web servers are detected too, not only what shows on the page.
• Implied stack. A technology that implies another adds it, such as WordPress bringing PHP and MySQL.

How to use Tech Stack Detector

1. Open Tech Stack Detector in the Apify Console. A free Apify account is enough to try it.
2. Paste your domains, one per line, or upload a list.
3. Click Start. Each domain is processed on its own, so one bad entry never loses the batch.
4. Download the results as JSON, CSV or Excel, or send them to your own tools with an integration.

Input

One field: domains. Use bare domains like stripe.com, not https://stripe.com/pricing.

Every line is checked before the run starts. Each must be a domain like stripe.com, not a company name; a run with any other line is refused with that line named, so a typo never costs you anything.

{
  "domains": [
    "stripe.com",
    "vercel.com"
  ]
}

Output

A domain we cannot resolve is skipped rather than returned empty, and you are not charged for it. The run log names every one that was skipped, so a short result is never a mystery.

{
  "domain": "allbirds.com",
  "cms": null,
  "ecommerce": "Shopify",
  "analytics": null,
  "tagManagers": "Google Tag Manager",
  "hosting": "Cloudflare",

      "confidence": 100
    },
    {

      "categories": [
        "Payment processors"
      ],
      "version": null,
      "confidence": 100
    }
  ]
}

FAQ

How many technologies can it detect?

Thousands, from CMS and ecommerce platforms to analytics, payments, frameworks and hosting, each with a confidence score.

Why is a version sometimes missing?

Many sites do not reveal it. When they do, in a generator tag or a script path, it is returned.

Am I charged for sites where nothing is found?

No. A site with no detectable technology, or one that cannot be reached, is skipped and not charged.

Do I need cookies, a login or proxies?

No. Tech Stack Detector works without cookies, accounts, proxies or API keys. Paste your domains and run it; everything else is handled for you.

Is it legal to use Tech Stack Detector?

Tech Stack Detector collects only publicly available information about the technology websites use. As with any data collection, you are responsible for how you use the results: follow the terms of the websites you work with and data protection laws such as GDPR wherever personal data is involved. If you are unsure about your use case, check with a lawyer.

Does Tech Stack Detector have an API?

Yes. Every run is available through the Apify API, with the JavaScript and Python examples above, and through the Apify MCP server for AI agents.
