GoKawiilDeveloper releases Onionspector to reveal what Tor sites can learn about visitors
A developer who previously built Onionservatory, a tool to audit Onion Service security configurations, has now released a companion tool called Onionspector. This new tool flips the perspective, showing users exactly what data points—from HTTP headers to browser fingerprinting signals like screen size, fonts, and Canvas/WebGL output—a website can collect about them when they connect, even over Tor.
