Website Tech Stack Detector — CMS, E-commerce, Analytics, CRM, Chat, Hosting & Email Provider

Paste a list of websites and find out what each one is built with: CMS and site builder, e-commerce platform, payment and review apps, analytics and tag managers, ad pixels, marketing automation / CRM / email marketing, live chat and helpdesk, cookie consent, JavaScript frameworks, hosting / CDN / web server — and the company's email provider (Google Workspace, Microsoft 365…) from MX records.

140+ technologies in 39 categories, one clean row per domain, ready for filtering in Excel or your CRM. A BuiltWith / Wappalyzer alternative for lead generation and market research.

How to run it in 3 steps

1. Add your input. In Websites or domains paste domains or homepage URLs, one per line — e.g. allbirds.com. The form is already filled with a working example, so you can skip this step for a first try.
2. Press Start. The prefilled run returns 3 results in about 4 s and costs about $0.006. Set Max results (cost cap) to cap the cost of bigger runs; you only pay for websites actually delivered.
3. Get the data. Open the Output tab and export JSON, CSV or Excel — or run it from the API, Make, Zapier, n8n or an AI agent (see below).

Features

• Lead-gen columns out of the box: cms, ecommercePlatform, analytics, marketingAutomation, liveChat, hosting, emailProvider, jsFramework — plus the full technologies list and technologiesByCategory.
• Email provider detection via MX records — know whether to pitch a Google Workspace or Microsoft 365 add-on.
• Careful fingerprints: our own rules prefer precision over noise (e.g. a file called bootstrap.js is not Bootstrap).
• HTTP only, no browser: pure HTTP, hundreds of sites per minute; offline sites are free.
• Pay per website: $2 per 1,000 analyzed sites.

Use cases

• Technographic lead lists: all Shopify stores using Klaviyo, all WordPress sites without a cookie banner, all HubSpot users…
• Sales qualification: enrich a CRM or Google Maps export with the prospect's stack.
• Competitor analysis: what do the leaders in a niche use?
• Agency prospecting: find sites on outdated platforms (Joomla, Magento 1, IIS…).

Use with AI agents (MCP), LangChain, RAG & the API

This actor is a ready-made tool for AI agents: an LLM can call it, wait for the run and read clean JSON back.

MCP server (Claude Desktop, Claude Code, Cursor, VS Code, any MCP client) — add Apify's hosted MCP server with this actor enabled as a tool:

{
  "mcpServers": {
    "apify": {
      "url": "https://mcp.apify.com/?tools=torix33/website-tech-stack-detector",
      "headers": { "Authorization": "Bearer <APIFY_TOKEN>" }
    }
  }
}

LangChain / LangGraph (pip install langchain-apify, set APIFY_API_TOKEN):

import json
from langchain_apify import ApifyActorsTool, ApifyWrapper
from langchain_core.documents import Document

# 1) give the actor to an agent as a tool
tool = ApifyActorsTool("torix33/website-tech-stack-detector")

# 2) or load results as Documents for a RAG index
loader = ApifyWrapper().call_actor(
    actor_id="torix33/website-tech-stack-detector",
    run_input={"websites": ["allbirds.com", "hubspot.com", "apify.com"], "checkEmailProvider": True, "includeEvidence": False, "maxConcurrency": 30},
    dataset_mapping_function=lambda item: Document(page_content=json.dumps(item, ensure_ascii=False), metadata={"url": item.get("url")}),
)
docs = loader.load()

REST API — one synchronous call, dataset items in the response:

curl -X POST "https://api.apify.com/v2/acts/torix33~website-tech-stack-detector/run-sync-get-dataset-items?token=<APIFY_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"websites": ["allbirds.com", "hubspot.com", "apify.com"], "checkEmailProvider": true, "includeEvidence": false, "maxConcurrency": 30}'

Also works with the Apify Python/JS clients, Make, Zapier, n8n, Google Sheets, webhooks and schedules. Export as JSON, CSV, Excel, XML or RSS.

RAG tip: Ideal as an agent tool for lead qualification: "is this prospect on Shopify and HubSpot?" — answer from ecommercePlatform and marketingAutomation.

Pricing

• $2.00 per 1,000 websites ($0.002 per website).
• The prefilled input returns 3 websites → $0.006.
• Example: 1,000 websites → $2.00; 10,000 → $20.00. Set Max results (cost cap) to limit any run.

Failed sites are free.

Limitations

• Detection uses the homepage HTML, response headers, cookies and DNS MX records. Technologies loaded only after login or deep inside an app may not be visible.

FAQ

Is it a BuiltWith or Wappalyzer alternative? Yes, for bulk lists: it fingerprints the homepage HTML, headers, cookies and DNS MX records and costs $2 per 1,000 sites.

Does it detect Google Workspace or Microsoft 365? Yes. emailProvider comes from the domain's MX records.

Why is a technology missing? Tools loaded only after login or deep inside an app are not visible on the public homepage.
