Identify Website Technologies in Safari on Mac

Know what can be observed

A page can expose scripts, markup and other signals that suggest a CMS, framework or analytics tool. Hidden back-end services may leave no reliable public signal.

• Separate directly visible script URLs from an inferred framework name.
• Expect a site to use more than one technology.
• Check more than one relevant page before generalizing to the whole site.
• Do not use a technology label as proof of a security weakness.

Use Web Technology Detector

The app is a Safari extension for Mac. Start on the page you actually want to research.

1. Install from the official App Store listing.
2. Enable the extension in Safari and review its website access permissions.
3. Open the page and run a technology check from the toolbar.
4. Review the results and verify important claims with visible page signals or documentation.

If a technology is not detected

Absence from a report does not prove absence from the site. A signal can be hidden, changed or available only on another page.

• Check that the page has finished loading.
• Review extension access to that page.
• Look at a second relevant public page.
• Keep uncertain results separate from confirmed observations.

Use the result in a practical audit

For a competitor review, record the URL, date, detected label and supporting signal. This makes the observation reviewable when the site changes.

• Compare pages by the same criteria.
• Confirm official integrations before planning migration work.
• Do not assume that detecting a tool means you know its private settings.
