Free vs Pro

See what stays free in your browser and what Pro unlocks.

Free

Included with the Chrome extension

  • Scan the current page locally (markup, scripts, globals, cookies) — no ExtHub account
  • Filter findings, copy names, and keep the last scan for this host
  • Works on normal http(s) pages (not chrome://, the Web Store, or extension pages)

Pro

Unlocked with an ExtHub subscription

  • Save scan reports to ExtHub (hostname and findings) and restore them in the popup
  • Recent chips for the last saves; open the full archive on exthub.app
  • Up to 50 records in the extension; search and CSV/JSON export on ExtHub

Why upgrade to Pro

  • Scan without signing in; Pro is optional for saved reports
  • Come back to a site later without scanning from scratch
  • One subscription, only for Stack Scout

About

Stack Scout scans the page you have open and lists technologies it can detect from markup, scripts, globals, and cookies. The scan stays in this browser — no ExtHub account for the free tools. Free: scan this page, filter findings, copy names, and keep the last scan for this host. Restricted pages (chrome://, the Web Store, extension pages) cannot be scanned. Pro can save a report (hostname plus findings) to ExtHub, restore it in the popup, and open the full archive on the site. The extension keeps up to 50 records; search and CSV/JSON export are on ExtHub. Results are heuristic — minified or server-rendered sites may show few or no matches.
