System-wide proxy
A transparent TUN routes the whole machine — browsers, automation, native apps. Choose how UDP is handled per session: block it, proxy it, or send it direct so voice and games still work without exposing your IP.

Everything runs through one clean tunnel.
PROXA is a Windows-native privacy layer: a system-wide proxy underneath every process, plus a per-profile fingerprint engine so each identity stands on its own.
Coherent fingerprints
Each profile gets its own canvas, WebGL, audio, font set, timezone, and hardware story — generated to stay consistent with your real host class, so a detector sees a believable machine instead of an obvious spoof.
Leak-proof routing
WebRTC, DNS, IPv6 and raw-socket paths are sealed at the routing layer. An interface-scoped kill switch blocks anything bound to the physical NIC, so a process can't quietly bypass the tunnel.
Profiles & fleet
Create hundreds of isolated browser profiles in bulk, drive them with recorded automations and a scheduler, and keep them organized — built for multi-account work at scale.
Encrypted cloud sync
Profiles sync selectively and encrypted — cookies, storage and settings move with you, while large local caches stay put. Open the same identity on another machine and pick up where you left off.
Antidetect & antitrack
Run a profile in antidetect mode to present a clean identity, antitrack mode to block trackers at the network layer, or both at once. The mode is set per profile, not globally.
Per-profile proxies
Assign a dedicated residential exit to each profile, or route the whole device through one. Mix per-profile browser proxying with the system tunnel as the job requires.
Windows-native install
A single bundled installer with the runtime, the tunnel engine, and the fingerprint hooks inside. Nothing to pip-install, no separate driver to babysit.
Account & entitlements
Sign in once; your plan and limits follow your account and your synced profiles. Log out and the app fully locks — no half-authenticated state.

We tried to deanonymize our own client with the proxy on. Here's what happened.
