Browser Identity Technology

True-to-Device Browser Identity Built from Real-Device Signals

Real-device signals, AI environment modeling, and cross-layer consistency work together to create one coherent browser identity per account.

Core Architecture

One Account. One Trusted Browsing Environment.

Web4 combines real-device signals with AI-assisted environment modeling to build an independent, coherent browser identity for each account—and keeps identity, session, storage, locale, and network context together inside the same environment.

Getting Started

Before You Get Started

A few practical details about access, compatibility, and core capabilities.

What’s the difference between a Free Account and Free Trial access?

Creating a Web4 account is free. Browser client trial access is separate and requires approval.

How is Web4 different from a traditional antidetect browser?

Web4 builds browser identities from real-device signals, AI environment modeling, and cross-layer consistency, then keeps that identity with the profile’s session, storage, locale, and network context.

Which desktop client is currently available?

The current trial referenced on this page is for the Windows client. Trial access is provided after approval.

Does Web4 support proxies and automation?

Yes. Profiles support per-profile HTTP, HTTPS, and SOCKS5 proxies plus visual workflows, CDP, headless execution, and AI-assisted browser actions.
