Tech Stack Detector: What Is Any Website Built With?

Find out which technologies any website uses, in bulk and at a fraction of the usual price. Detects 3,600+ technologies: CMS, ecommerce platforms, analytics, tag managers, marketing automation, CRM, payments, live chat, A/B testing, CDN, hosting, frameworks and more, with versions where visible.

It also reads public DNS records to show what most tech lookups miss: the company's email provider (Google Workspace, Microsoft 365...), email sending tools (HubSpot, Mailchimp, SendGrid, Salesforce...) and business tools verified on the domain (Atlassian, Stripe, Zoom, Slack, OpenAI and more).

Ideal for sales prospecting (find every Shopify store or HubSpot customer in a list), lead scoring, competitor research, market sizing and AI agents.

Why this tool?

• 💸 Low price, pay per website. Failed and blocked websites cost only a tiny flat fee (a tenth of a cent).
• ⚡ Fast. No browser needed, so large lists finish in minutes.
• 📬 DNS signals included. Email provider and verified business tools, not just what's on the page.
• 🧹 Easy input. Domains, URLs or email addresses; duplicates removed.
• 🤖 Works with AI agents through the Apify MCP server, and with Make, n8n and Zapier.

Pricing

Pay per website scanned. See the Pricing tab for your plan's rate. Websites that fail or block us cost a flat $0.001 each, because they still use server time. Set Maximum cost per run to cap your spend.

Event	When it is charged	Price per 1,000 (Free / Bronze / Silver / Gold plan)
Website scanned	Each website scanned and returned.	$5 / $4 / $3.50 / $3
Website failed	A website that could not be reached or blocked us (it still uses server time).	$1.50 on every plan

Need more speed? Give the run more memory: it scans 4 websites at once per GB. Residential proxies are not supported.

Notes

Detection uses the page's HTML, headers, scripts, cookies, robots.txt, TLS certificate and DNS records, without a browser. Technologies that only load after JavaScript runs may be missed. Fingerprints are based on the MIT-licensed Wappalyzer 6.10.54 release, extended with our own.
