Frequently Asked Questions

Our detection engine uses 150+ fingerprint rules, matching multiple signals — HTML source, JavaScript variables, CSS class names, and HTTP response headers. For mainstream CDNs, analytics tools, and CMS platforms, accuracy exceeds 95%. We continuously expand the fingerprint database to cover new tools and platforms.

Yes. The detector fetches the target URL through a server-side proxy to retrieve the HTML source and HTTP headers for analysis. We do not store browsing history, and scan results are only shown in the current session.

Absolutely. The tool automatically prepends https:// to URLs that don’t include a protocol. Both HTTP and HTTPS websites are fully supported.

Yes – the technology stack detection is completely free. No signup, no account, no usage limits.

Currently we support WordPress, Shopify, Squarespace, Wix, Webflow, Joomla, Drupal, Magento, Ghost, and more. New platform fingerprints are added regularly based on user feedback.

Not yet. The current version is single-site only. Bulk scanning and custom filters are on our roadmap

Some tools are deliberately lightweight and leave few fingerprints (e.g. server-side caching, custom JavaScript). We can only detect technologies that emit detectable signals. If a tool is missing, send us a request and we’ll add its fingerprint.

The free tool includes reasonable usage limits to prevent abuse. There is no hard daily cap for normal usage.
