Three steps from curiosity to a shareable, structured stack report.
Add Stack Spy from the Chrome Web Store. It runs only when you use it — scan the site you are visiting on demand.
We analyze scripts, headers, HTML, and known fingerprints to map technologies into categories (CMS, CDN, analytics…).
Each domain gets a clean public page like https://stack-spy.com/companies/example.com — perfect for SEO and team sharing.
