Website Tech Stack Detector: Technology Lookup for CMS, Shopify, Frameworks, Analytics & Email Provider

A BuiltWith/Wappalyzer-style lookup in bulk. Give it a list of websites and get each site's technology stack: CMS, e-commerce platform, JavaScript frameworks, analytics and tag managers, CDN and hosting, payment providers, email provider and SaaS tools, with versions where the site exposes them.

It uses 4,000+ open fingerprints from the HTTP Archive fork of Wappalyzer, which is also used for the HTTP Archive Web Almanac.

What you can use it for

• Sales and lead qualification: filter prospect lists by "uses Shopify", "uses HubSpot" or "on WordPress", or check what a competitor uses.
• Agencies: check a prospect's stack before a pitch (outdated CMS version, no analytics).
• Security and IT inventory: spot outdated, exposed versions across your own domains.
• Market research: measure technology adoption across a list of domains.

How to use it

1. Paste website domains under Targets (thousands per run are fine).
2. Keep Check DNS on to detect email providers and SaaS verification records.
3. Click Start.
4. Filter the table, e.g. technologyNames contains "Shopify", and export your list.

What it looks at

Signal	Example detections
HTTP headers and cookies	Nginx 1.25.3, Cloudflare, PHP 8.2, Shopify, Varnish
HTML, meta tags, script URLs, inline scripts	WordPress 6.6, jQuery 3.7.1, Google Tag Manager, HubSpot, React, Next.js
DOM selectors	Page builders, theme frameworks, consent banners
DNS (MX, TXT, NS, SOA, CNAME)	Google Workspace, Microsoft 365, SendGrid, Mailgun, Salesforce, Zendesk, DNS host
TLS certificate issuer	Let's Encrypt, Sectigo, DigiCert
Implied technologies	WordPress → PHP and MySQL

Input

{ "targets": ["wordpress.org", "github.com"], "checkDns": true, "minConfidence": 50, "flattenOutput": true }

Output (one item per site)

{
  "input": "wordpress.org", "finalUrl": "https://wordpress.org/", "status": 200, "technologyCount": 12,
  "categories": ["CMS", "Databases", "Web servers", "Tag managers", "..."],
  "technologyNames": "WordPress 7.2, MySQL, PHP, Nginx, Google Tag Manager, Gutenberg 24.2.0, ...",
  "technologies": [
    {"name": "WordPress", "version": "7.2", "confidence": 100, "categories": ["CMS", "Blogs"],
     "website": "https://wordpress.org", "oss": true, "saas": null, "pricing": [], "cpe": "cpe:2.3:a:wordpress:wordpress:*:*:*:*:*:*:*:*",
     "detectedVia": ["meta"]}
  ]
}

Limits

• This is a static analysis of the first page plus DNS. Technologies that can only be seen by running JavaScript in a browser (about a third of the fingerprints are JS-global checks) can be missed, so expect fewer detections than a full-browser scan on heavily client-side sites.
• Only public pages are checked: one page load per site, no logins. Requests to private or internal addresses are refused.
• Detections are probabilistic. confidence and detectedVia show how each result was found.

API, integrations and AI agents (MCP)

Run it from your own code with the Apify API and get the results in one call:

curl -X POST "https://api.apify.com/v2/acts/manageable_gully~website-tech-detector/run-sync-get-dataset-items?token=<YOUR_APIFY_TOKEN>" \
  -H "Content-Type: application/json" -d @input.json

from apify_client import ApifyClient
run = ApifyClient("<YOUR_APIFY_TOKEN>").actor("manageable_gully/website-tech-detector").call(run_input={...})

• No-code: use the Apify app in n8n, Make or Zapier ("Run Actor", then "Get dataset items"), or send results to Google Sheets, Slack or a webhook.
• AI agents (MCP): add https://mcp.apify.com?tools=manageable_gully/website-tech-detector to Claude, Cursor, VS Code or any MCP client and the agent can call this Actor as a tool.
• Schedules: run it hourly, daily or weekly from Apify Console.

FAQ

Is this a BuiltWith or Wappalyzer replacement? For bulk lookups of current technology, yes: it uses the open Wappalyzer fingerprint set (HTTP Archive fork). It does not offer BuiltWith's historical data or lists of all sites using a technology.

Can I find Shopify or WordPress stores? Give it a list of domains and filter by technology. It checks the sites you provide; it does not discover new sites by itself. For new startup websites, try the Product Hunt Scraper.

Can AI agents use it? Yes. It is available as a tool through the Apify MCP server (https://mcp.apify.com?tools=manageable_gully/website-tech-detector) and the Apify API, and it returns structured JSON that agents can read directly.
