A review of ShardX — a free antidetect browser from ProxyShard. We looked at its features and checked the quality of its browser fingerprint. The launcher and user interface of the project are open source, but the modified Chromium remains closed and is downloaded from ProxyShard’s CDN on first launch. The browser is designed for multi-accounting and automation, supports a local API, an SDK for several programming languages, and MCP, which allows profiles to be managed programmatically and through AI tools.

CPA.RIP’s take: the ShardX antidetect browser can be used for work. Testing showed that the masking works correctly: the services Whoer, Iphey and Pixelscan rated the digital identity as reliable and safe.

Testing the Antidetect Browser

A selection of services for checking browser anonymity, fingerprints, etc.: https://cpa.rip/services/checking-browser-fingerprints-and-anonymity/.

Summary table of anonymity and digital fingerprint parameters:

• Whoer: Shows 100% anonymity.

• Iphey: Considers the digital identity “Trustworthy,” identifying no critical issues.

• Pixelscan: The fingerprint is stable, with no signs of masking or automation detected.

Key Features

• Isolated browser profiles
• 170 ready-made device configurations available for Windows, macOS, and Linux.
• The browser modifies digital fingerprint parameters, including WebGL, Canvas, Audio, Client Hints, fonts, screen, geolocation, time zone, TLS ClientHello, and JA4.
• Fingerprint modifications are implemented at the level of the modified Chromium without using JavaScript injections.
• HTTP, HTTPS, and SOCKS5 proxies are supported, and when using SOCKS5 with UDP, WebRTC and QUIC (HTTP/3) are available.
• The interface language, geolocation, and time zone can be automatically configured according to the proxy used.
• Chromium and the fingerprint library are updated automatically via ProxyShard’s CDN.

Adding a Proxy

In the Proxies section, click New proxy.

Paste the proxy in one of the selected formats and click Parse.

Creating a Profile

In the Browser section, click New profile.

Set the profile name, choose the operating system: macOS, Windows, and Linux are available. Select the added proxies and click Create profile. Configure additional parameters as needed.

Automation and API

One of the key features of the ShardX Launcher is its advanced automation system.

The browser provides a local API that allows you to:

• create and delete profiles;
• start and stop profiles;
• retrieve profile information;
• obtain a CDP WebSocket to connect automation tools;
• manage the profile lifecycle.

Official SDKs are available for developers:

• Python;
• Node.js;
• Rust.

In addition, support for MCP (Model Context Protocol) has been implemented, allowing the browser to be controlled through Claude Desktop, compatible IDEs, and other AI clients.
