Website Tech Stack, Ad Pixels & DNS Detector by Domain

Give it company websites, get one short row per company: which ad pixels and analytics run on the site, the marketing tools, CMS or e-commerce platform, hosting, and what the domain's DNS says about email (provider, sending services, DMARC policy).

Quick start

Detect website frameworks, advertising pixels and DNS email signals.

Example input:

{
  "domains": [
    "stripe.com"
  ],
  "track_diff": false
}

Example successful output (illustrative values, selected fields; not current measurements):

{
  "domain": "stripe.com",
  "status": "ok",
  "frameworks": [
    "Next.js",
    "React"
  ],
  "email_provider": "Google Workspace",
  "technology_count": 2
}

Price: $0.003 per analyzed domain.

Built for lead qualification and AI agents: flat fields such as has_meta_pixel and has_google_ads_tag answer "does this company advertise?" without reading a long list.

Use this when you need to qualify or segment companies by their stack. Do NOT use it for traffic numbers or ad spend.

Input

{ "domains": ["stripe.com", "notion.so", "gymshark.com"] }

Field	What it does
domains	Company websites, up to 100 per run. Full URLs are fine.
track_diff	Compare with your previous run and fill added and removed.
state_id	Name of the saved history, one per watchlist.
only_changes	With track_diff: return only domains whose stack changed.

Output (one row per domain)

{
  "domain": "gymshark.com",
  "status": "ok",
  "has_meta_pixel": true,
  "has_google_ads_tag": true,
  "has_ga4": true,
  "has_gtm": true,
  "has_linkedin_insight": false,
  "has_tiktok_pixel": true,
  "ad_pixels": ["Meta Pixel", "Google Ads", "TikTok Pixel"],
  "analytics": ["Google Analytics 4", "Google Tag Manager"],
  "marketing_tools": ["Klaviyo"],
  "cms": null,
  "ecommerce": "Shopify",
  "hosting_cdn": ["Cloudflare"],
  "email_provider": "Google Workspace",
  "spf_senders": ["Google Workspace", "Klaviyo"],
  "dmarc_policy": "reject",
  "verified_services": ["Google Search Console", "Meta Business"],
  "technology_count": 9
}

The example shows the format; run the Actor for real values. status is ok, blocked (the site refused automated access), unreachable, invalid_input or not_checked. Only ok is charged.

A small run summary is saved to the key-value store under OUTPUT. It also lists related_tools: other HirePulse tools that add data for the same input.

How it works

• One plain HTTP request to the home page. No browser, no proxy.
• About 60 technologies are recognised by their public script hosts, tag IDs and response headers, from our own signature list.
• Ad pixels and analytics configured inside the site's Google Tag Manager container are found too.
• DNS (MX, TXT, DMARC) is read over DNS-over-HTTPS.

A BuiltWith / Wappalyzer alternative for the questions sales and marketing teams ask most.

Limitations

• Only the home page is checked. Tools loaded only on other pages, or only after a cookie consent click, may be missed.
• Websites that block automated requests are reported as blocked and not charged.
• Detection is pattern-based; it tells you a tag is present, not how it is used.
