Detection research

What we see when we put a tool on the bench. Antidetect browsers signal by signal, headless and automation frameworks, TLS fingerprinting, and the proxy networks underneath all of it.

About the lab reports. Lab reports here come from our own harness: a browser profile with its JavaScript-visible identity rewritten, pointed at our own detector, with the tool and version named and the run dated. The harness sees nothing below JavaScript and is not the commercial tool itself, so each report says what it measured and what it cannot show.
