Who Are You 2026.11.15

Who Are You is a browser privacy self-check. Open https://who.1ms.dog and it shows, in one page, what a website can tell about you before you log in: exit IP and ASN, whether your timezone and language match that IP, WebRTC and DNS leaks, and canvas/WebGL/font hardware signals. It is meant for people who use a VPN or private window and want to see what still lines up. The same hardware hash often survives a cleared cookie jar; timezone and language usually stay put when the exit IP changes. The code is MIT on GitHub (https://github.com/yt1988/who-are-you) and can be self-hosted as a Cloudflare Worker. Optional anonymous usage counts can be turned off. I am the author (Yang / yt1988). This listing text was prepared with AI assistance. Known limits: some font and clock heuristics misread unusual Linux setups; the page is a check, not a full anonymizer.
