VirtualBrowser is a free, open-source anti-fingerprint browser built on Chromium that runs multiple isolated browser identities on one Windows machine, for people who need to keep accounts and sessions from being linked together.
What it is
VirtualBrowser (指纹浏览器) is an open-source fingerprint browser licensed under BSD-3-Clause and built on Chromium, shipped as a desktop application whose interface is written in Vue on top of vue-element-admin. It runs on Windows 7 and newer and lets a user create and manage multiple mutually isolated browser environments on a single device, with macOS, Android, and Linux ports described as planned. The repository has 3,108 stars, 487 forks, and 14 open issues, and it is tagged with anti-detection, fingerprint-browser, multi-account, privacy-tools, proxy-support, and web-scraping topics.
The problem it solves is browser fingerprinting, the digital signature assembled from browser, operating system, and hardware traits such as User-Agent, language, resolution, fonts, and Canvas/WebGL noise, which can be used to identify or link a user across sessions. VirtualBrowser isolates each environment's fingerprint so accounts are harder to associate or track, replacing the practice of reusing one shared browser identity across many accounts. Because it lives in the Chromium ecosystem, it stays compatible with Playwright and other Chromium automation tooling.
Key capabilities
- Multi-environment isolation: create several independent fingerprint profiles on a single Windows 7 or newer machine.
- Centralized management: create, launch, edit, and delete browser environments from one interface.
- Broad fingerprint coverage: control
userAgent operating system and browser version fields, proxy (default, none, or custom), navigator.language / navigator.languages, Date timezone, navigator.geolocation, and screen.width / screen.height.
- Noise injection for Canvas/WebGL and AudioContext, covering 2D and WebGL drawing plus
getChannelData and getFloatFrequencyData.
- WebRTC leak protection, alongside ClientRects, Speech Voices, device name and MAC, Do Not Track, SSL, port scan protection, and hardware acceleration options.
- IP-based auto-matching of language, timezone, and geolocation.
- Automation-friendly design: compatible with Playwright and other Chromium tools, with sample code in the
automation/ directory.
Who uses it and how
- Web3 airdrop participants who run and separate multiple accounts, which the project explicitly targets as a free tool for that purpose.
- Multi-account operators who need many isolated identities on one Windows machine rather than many separate devices or virtual machines.
- Web scraping and data-extraction teams, matching the registry category Data & Analytics / Data Extraction & Web Scraping and the web-scraping topic.
- Automation developers who drive isolated environments through Playwright or other Chromium automation tools.
Getting started
Installation is by downloading the latest installer package from the GitHub Releases page or from the official sites virtualbrowser.cc and vbbrowser.com, after which a browser environment is created and launched from inside the application.
How it compares
No comparable anti-fingerprint browser is named in the facts supplied for this registry, so VirtualBrowser stands alone in this listing. The only related tools the project cites are verification and rendering dependencies, FingerprintJS, BrowserLeaks, and Chromium itself, which are used to check or host the fingerprint behaviour rather than to compete with it.
When to use it — and when not to
VirtualBrowser is a Windows-only desktop application, so anyone on macOS, Android, or Linux must wait for the planned ports, and teams wanting a server-hosted or headless fleet are not served by it today. Users should also read the project's own disclaimer, which states it is provided for technical exchange, learning, and research only and must not be put to unlawful or destructive use. The README is written primarily in Chinese, and no paid support tier is mentioned.
