Mirror
What any server learns about you the moment you connect — before cookies, before JavaScript. Nothing is stored.
$ GET /api/mirror — a single request, no parameters
✓ TLS handshake done · the server already knows everything in the left panel
▲ the right panel never touched the network — it was read locally by your browser
// what the server sees● via worker
reading the request…
read by the Worker at the handshake · never logged
// what your browser tells◆ local, no network
read on this page · never sent anywhere
▲ Why it matters: The combination of these values — no cookies, no login — is enough to re-identify most browsers across visits. This is how tracking survives "clearing cookies". The defense is not hiding one field, it is shrinking the surface: browsers with anti-fingerprinting, resistance to third-party scripts, and sites (like this one) that collect nothing.
🛰️ This tool talks to the Worker (dynamic/) — what is sent and why is explained above.
