Overview

Find out what any website is built with. The Tech Stack Detector scans a website and identifies the technologies behind it: CMS, ecommerce platform, analytics and tag managers, JavaScript frameworks, web server, CDN, hosting provider, payment processors, marketing automation, live chat, email provider and more. It recognizes 7,600+ technologies, with versions where available.

Paste one domain or a list of thousands of websites and get one clean row per site, with every detected technology grouped by category. Export to JSON, CSV or Excel, or send the results straight into your CRM, spreadsheet or data pipeline.

It's a fast, low-cost Wappalyzer alternative and BuiltWith alternative for lead generation, sales prospecting, competitor research, market sizing and technographic data enrichment.

What does Tech Stack Detector do?

🔍 Detects 7,600+ technologies, including WordPress, Shopify, Magento, WooCommerce, Webflow, Wix, Squarespace, HubSpot, Salesforce, React, Next.js, Vue, Angular, Google Analytics, Google Tag Manager, Fastly, AWS, Vercel, Netlify, Stripe, PayPal, Klaviyo, Intercom, Zendesk and thousands more.
🏷️ Groups results by category, so CMS, ecommerce, analytics, frameworks, hosting, CDN, payments, marketing automation, advertising, security and databases each get their own column.
🔢 Reports versions, for example WordPress 7.2 or styled-components 6.1, which helps with upgrade targeting and security audits.
📧 Identifies the email provider (Google Workspace, Microsoft 365, Zoho and others) and the DNS host from public DNS records.
🔒 Includes SSL certificate issuer, IP addresses, web server and X-Powered-By details.
⚡ Bulk scanning runs many websites in parallel, so large domain lists finish fast.
📤 Exports to JSON, CSV, Excel and HTML, or connects with Zapier, Make, n8n and Google Sheets.

Why use a website technology checker?

Knowing a company's tech stack tells you a lot about it: its budget, its maturity, what it already pays for and what it might buy next. Sales and marketing teams use technographic data to:

Build targeted lead lists, such as every Shopify store in a niche, every site still running an old WordPress version, or every company using a competitor's product.
Personalize outreach: "I noticed you're on Magento 2 with Klaviyo…" lands far better than a generic pitch.
Research competitors: see which analytics, A/B testing, CDN and ecommerce tools they rely on.
Size a market: count how many sites in your list use each platform.
Run agency and freelancer audits: understand a prospect's stack before the first call.
Do security and IT due diligence: spot outdated frameworks and server software across a portfolio.

How to use Tech Stack Detector

Paste your websites or domains, one per line. Full URLs (https://www.example.com) and bare domains (example.com) both work.
Optionally keep Deep scan site scripts and Include DNS & email provider switched on for the most complete results.
Click Start. When the run finishes, download the results as JSON, CSV or Excel, or open the Overview table.

How much does it cost to check a website's tech stack?

Tech Stack Detector uses simple pay-per-website pricing: you pay for each website successfully scanned, and unreachable sites are not charged. That makes it far cheaper than per-seat technology lookup subscriptions, and higher Apify subscription plans get an automatic discount. See the Pricing tab for the current price per website.

Tips for the best results

Bare domains are fine. example.com is upgraded to https://example.com and redirects are followed automatically.
Keep deep scan on to detect frameworks and libraries loaded from the site's own script files.
Schedule a run weekly or monthly to track when prospects or competitors switch platforms.
Combine it with the Google Maps scraper or a company list to build fully enriched lead lists.

FAQ

What technologies can it detect? More than 7,600 across 100+ categories, including CMS, ecommerce, analytics, advertising, frameworks, hosting, CDN, payment, email, security and marketing tools.

Does it detect the version of a technology? Yes, whenever the website exposes it (for example in a generator tag, a script URL or a response header).

How accurate is it? Each detection comes with a confidence score, and only technologies at 50% confidence or higher are returned. Like any external technology checker, it sees what a website publicly serves; tools used only behind a login or only on the server can't be observed.

Can I scan thousands of websites? Yes. Paste or upload a large list and raise Parallel scans for speed.

What happens if a website is down? It still gets a row with an error message so your list stays complete, and you are not charged for it.

Can I use this for lead generation? Yes. Filter the CSV by ecommerce = Shopify, cms = WordPress, mxRecords containing outlook, and so on, to build targeted prospect lists.

Can I integrate it with my tools? Yes. Results connect to Google Sheets, Zapier, Make, n8n, Slack, webhooks and any HTTP client through Apify integrations.
