FAQ

How does tech detection work?
The tool looks at tell-tale signatures: HTML markers, script paths, generator meta tags, cookie names and server headers. It is the same public information any browser can see.
Why is a technology missing?
Some sites hide or obfuscate their stack, and JavaScript-injected code may not appear in the raw HTML. Detection covers the most common 40+ technologies.
Can I inspect a competitor site?
Yes — the tool works on any public website, which makes it handy for competitive research.
Is it free?
Yes, completely free with no signup. Results are cached for 6 hours.
