Website Tech Stack Detector — CMS, ecommerce, analytics & email provider

Find out what technologies any website uses, for a whole list of domains at once. Perfect for sales prospecting ("all Shopify stores using Klaviyo"), competitor research, market sizing and lead qualification.

What it detects (150+ technologies)

Email (from DNS)	Google Workspace, Microsoft 365, Zoho, plus sending tools: SendGrid, Amazon SES, Mailgun, Mandrill

The email provider from DNS (MX/SPF records) is something most technology detectors miss, and it tells you a lot about a company: Google Workspace vs Microsoft 365, and which tools send their emails.

Why this one

• Summary fields for quick filtering: cms, ecommerce, emailProvider, hosting, cdn, frontendFramework.
• Evidence for every detection (which script, header, cookie or DNS record matched).
• Gets past blocks: retries through Apify Proxy and a residential IP when a site refuses the server.
• Pay only for websites that could be analysed. Unreachable sites are listed with the reason, free.

How much does it cost?

You pay only for results delivered, at a fixed price per item. Apify platform usage is included in that price, so there are no compute costs on top. Errors and items that couldn't be found are free.

What you get	Price	Example
Website analysed	$0.005 each	1,000 website analyseds = $5.00

The Apify Free plan includes $5 of monthly credit, enough for about 1,000 website analyseds per month at no cost. You can also set a maximum spend per run.

On paid Apify plans it gets cheaper automatically: 10% off on Starter, 20% on Scale and 30% on Business.
