Website Technology Detector: CMS, Analytics, Payments & Email Provider

Paste a list of domains and get, for each website, the technologies it runs on: CMS and ecommerce platform, analytics and ad pixels, live chat, payments, marketing automation, hosting and CDN, JavaScript frameworks, and more. From public DNS it also finds the email provider (Google Workspace, Microsoft 365 and others), the services that send email for the domain (SendGrid, Mailchimp, HubSpot and others) and SaaS tools the company has verified (Slack, Atlassian, Zoom, Notion, OpenAI and others). It also collects the company's social links.

Use it to qualify lead lists ("all Shopify stores using Klaviyo"), size a market, find prospects using a competitor, or enrich a CRM.

Only the home page of each domain is opened, like a normal browser visit. There is no login, no deep crawling and no CAPTCHA handling.

Input

{
  "domains": ["stripe.com", "https://www.zalando.de/", "notion.so"],
  "includeDns": true,
  "includeSocialLinks": true,
  "maxConcurrency": 8,
  "timeoutSeconds": 15
}

• domains: up to 5,000 domains or URLs. Duplicates are removed.
• includeDns: check MX and TXT records over DNS-over-HTTPS (Cloudflare, with Google as a fallback).
• includeSocialLinks: collect LinkedIn, X, Facebook, Instagram, YouTube, GitHub and TikTok links from the home page.
• maxConcurrency, timeoutSeconds: speed and patience per website.

A run summary (domains checked, detected, failed, invalid inputs) is saved to the OUTPUT record.

What it detects

About 135 technologies in 37 categories, including WordPress, Shopify, Wix, Squarespace, Webflow, Drupal, Magento, WooCommerce, BigCommerce, HubSpot, Marketo, Klaviyo, Mailchimp, Google Analytics, Google Tag Manager, Segment, Hotjar, Mixpanel, Meta Pixel, LinkedIn Insight Tag, Intercom, Drift, Zendesk, Stripe, PayPal, Klarna, React, Next.js, Vue.js, Cloudflare, Vercel, Netlify, Google Workspace and Microsoft 365. Versions are reported when the site shows them.

Good to know

• Detection reads what a visitor's browser receives on the home page. Tools loaded only on other pages or only after a click may be missed.
• Some websites block automated visits. Then ok is false with the reason in error, unless DNS still revealed something.
• You pay only for domains where something was found (ok: true). Failed domains are returned for free.
