ProxyBro

One identity per account. Never linked.

The problem

Running multiple accounts means each has to look like its own real device. A proxy alone isn't enough — if your fingerprint (timezone, language, WebGL, canvas) doesn't match the proxy's country, you're flagged. Keeping dozens of identities coherent by hand is impossible.

What I built

Turns a list of proxies into identities — each a saved profile with its own proxy and a country-matched fingerprint (user-agent, platform, Client Hints, WebGL, canvas, timezone and language all consistent with the exit IP).
One tap applies the proxy, the fingerprint and WebRTC-leak protection together — switch identity, switch account, cleanly.
Windows-only or Diverse (Win / Mac / Linux) mode — every identity gets a unique device profile and canvas seed, so two accounts never share a fingerprint.
Bulk-import a proxy list and turn the working ones straight into identities.
In-app Diagnostics: exit IP, WebRTC leak check and fingerprint coherence — a plain-language verdict plus an expert breakdown.

ProxyBro identities — Your identities — tap one and its proxy, fingerprint and leak protection apply together.

Diagnostics — exit IP, WebRTC and fingerprint coherence, with a plain-language verdict.

Bulk import — paste a proxy list, turn the working ones into identities.

The result

Live on the Chrome Web Store, MIT-licensed, with proxybro.app as its home — latest release v1.23.4 (Edge Add-ons in review). Built honest: it's a privacy tool for sequential, one-account-at-a-time use — it switches the proxy and fingerprint, but doesn't pretend to be a full anti-detect browser.
