Frequently asked questions
How does tech stack detection work?
We analyse multiple signals: HTTP response headers, HTML meta tags, JavaScript variable names, cookie names, URL patterns, and DNS records. Each technology leaves unique fingerprints.
Can I see my competitor's tech stack?
Yes — tech stack detection works on any public website. Many companies use this to research competitor tools and find cost-saving alternatives.
Is my tech stack visible to others?
Most technology fingerprints are visible to anyone who knows what to look for. This is normal and not a security risk. Sensitive information like server paths should still be protected.
Why would I want to know my own tech stack?
To audit what tools are actually installed (vs. what you think is installed), find redundant tools, verify CDN configuration, and check for outdated or vulnerable libraries.
