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.

True-to-Device Browser Identity built from verifiable signals Eight browser and network signal categories converge through cross-layer consistency into a true-to-device browser identity. The identity runs inside a trusted browsing environment where identity, network, browser data, and session state remain together for the profile.

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.

Included in the Windows trial

Browser Identity & Profiles:
identity modeling, saving and reuse.
Proxy & Network:
proxy configuration and diagnostics.
Team Permissions & Logs:
members, permissions, logs and handoff.

AI workflows, Headless & CDP and Skills & MCP are outside this trial’s scope.

Do I need to register before applying?

No. Submit your email on the trial application page. The Web4 team reviews applications and manually emails approved applicants with download instructions. Install the client, then register your account.

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?

Trial applications are for Windows. macOS access will follow Windows.

How do profiles and proxies work together?

Each profile keeps its browser identity, cookies and saved session together. Its proxy settings keep the account’s browser and network configuration organized around the same profile.

What does unlimited profile creation mean?

During the free trial campaign, approved users can create unlimited browser profiles for free after installing the client and registering an account. Unlimited applies to profile creation, not to team size, storage, concurrency, AI usage or automation. The campaign end date and post-campaign policy have not yet been set.
