Tech-Stack Detector

Find the technologies behind any website, in bulk: CMS, e-commerce platform, analytics, ad pixels, JavaScript frameworks, CDN and hosting, with versions and confidence.

What it does

• Checks each site with one fast request and matches over 7,600 open technology fingerprints.
• Ready-made columns: CMS, e-commerce, analytics, advertising (ad pixels), frameworks and hosting.
• Full list of detected technologies with categories, version (when the site reveals it) and confidence.
• Adds implied technologies (WordPress implies PHP and MySQL, for example).
• Lists sites it couldn’t check in FAILED_URLS; you aren’t charged for those.

Why this one: Over 7,600 technology fingerprints, ready-made CMS / analytics / ad-pixel / hosting columns, versions where the site reveals them, and a fast HTTP check instead of a full browser, so bulk runs stay cheap.

In our last check, 20 runs over varied inputs succeeded 100% of the time.

Use cases

• Lead lists: find stores on Shopify or sites using a competitor’s tool
• Market research on which tools a sector uses
• Auditing your own sites’ tags and pixels

Pricing

Pay per result: $3.00 per 1,000 results. You pay only for results you get; Apify platform costs are included. Set a maximum charge for a run and the Actor stops cleanly when it's reached, keeping everything collected so far.

Tips

• Raise "Minimum confidence" to 75 or more for fewer, surer results.
• Some technologies only show in a live browser (they run purely in JavaScript); this fast check covers what’s in the page, headers and cookies.
