Web4 Browser is an AI antidetect browser and multi-accounting workspace built around one persistent browser environment.
At the identity layer, Web4 resolves coherent browser identities from real-device signals and AI environment modeling instead of relying only on manually configured fingerprint parameters. Identity, network context, session state, and execution context stay with the same profile, while team controls govern access and review around it.
WEB4 BROWSERBrowser EnvironmentIdentity, network, session, and execution share one profile context.
Environment readyEach capability has a focused job. Together they keep browser identity, network routing, session state, and execution connected to the same saved profile, while tools and team controls extend and govern that context.
Define how a profile identifies itself and where its traffic comes from.
Build isolated profiles whose identities are modeled from real-device signals. Cookies, storage, login state, and other account context stay separated by profile.
Assign HTTP, HTTPS, or SOCKS5 proxies per profile, with routing, location, timezone, and network context kept inside the same browser environment.
Use the same saved profile for AI-assisted tasks and repeatable background automation.
Turn natural-language tasks into browser actions inside a saved profile, reusing its identity, session, proxy, locale, timezone, and other saved profile context.
Run the same profile headlessly or through CDP-compatible automation without rebuilding saved session, proxy, browser settings, or run context.
Extend what profiles can do, then control who can use them and review what happened.
Package repeatable browser steps as reusable skills and connect approved MCP tools to the profile that owns the expected session.
Organize profile access with roles and projects, with activity and execution records available for review, troubleshooting, and team handoff.
Web4 keeps browser identity, session state, proxy, locale, and storage attached to the same profile whether work is opened manually, handled by AI, or executed through headless and CDP automation. Team permissions and activity records govern access and review around that shared profile context.
Real-device signals and AI environment modeling establish the browser identity and isolated profile.
Proxy, locale, timezone, cookies, storage, and session remain attached to Profile #16.
Use the same saved profile yourself, with AI workflows, or through headless and CDP automation.
Reusable skills and approved MCP tools extend browser execution while Profile #16 remains the source of context.
Team permissions and activity records govern access to shared browser work and keep it visible, traceable, and reviewable.
