What is this site actually built on?

Knowing the platform changes which fixes are even available, and knowing which tags are present explains tracking gaps. This check reads the page and its headers and matches them against known platform and tag signatures.

Runs the Tech stack check on the address you enter, from outside your network. Nothing is stored.

What this check inspects

Shipwork fetches the page and reads its markup (tags, attributes, asset URLs and script code) and the response headers, never the visible text, so a page that merely writes about a platform is not mistaken for running it. It matches that markup against signatures for the common platforms: Shopify, WooCommerce, WordPress, BigCommerce, Magento, Wix, Squarespace and Webflow. It does the same for analytics and advertising tools: Google Analytics 4, Google Tag Manager, Meta Pixel, TikTok Pixel, Hotjar, Klaviyo, Microsoft Clarity and Pinterest Tag. It also reports an X-Powered-By header when one is present, and notes when a review platform such as Trustpilot, Judge.me, Yotpo, Okendo or Stamped is detected.

What a failure means

This check is mostly informational: it tells you what was detected rather than what is wrong. The one warning is the absence of any advertising or analytics tag, because conversion tracking cannot work without one. Everything else, the platform, the tags, the X-Powered-By value and the review platform, is reported for context. A missing X-Powered-By is not a finding at all.

How to fix it

  1. Install a conversion tag if the check found none and you run paid traffic, so conversions can be attributed.
  2. Remove tags for tools you no longer use, since abandoned pixels still load and slow the page.
  3. Use the platform name the check reports to pick the right fix path in the related guides.
  4. Suppress a version-revealing X-Powered-By header if you would rather not advertise the stack.

A typical failure, worked through

The setupA store migrated from Shopify to a custom theme on another platform but left the old Shopify pixel and a retired analytics tag in the head.

What the check reportsThe check reports the current platform, then lists both the old and the new tracking tags, and notes a review platform that is no longer in use on the site.

The pointA stack accumulates tags over time. Seeing the full list is the quickest way to find the ones that now cost bandwidth and track nothing useful.

Questions

How does it detect the platform?
By matching known signatures in the page HTML and response headers, such as Shopify CDN URLs, wp-content paths or Wix static hosts. It reports only what the signatures show.
Why does a missing tracking tag matter?
If you run paid ads or rely on conversion data, no analytics or advertising tag means no attribution and no remarketing. That is the one warning this check raises.
Is it a problem that the header reveals my stack?
It is informational. Hiding the X-Powered-By value narrows what an attacker learns, but its absence is not itself a finding.
