Web4 Browser - 2026 Pricing, Features, Reviews & Alternatives

Web4 Browser is a desktop AI fingerprint browser and browser automation platform available for Windows, macOS, and Linux. It integrates independent browser profile environment management, proxy IP management, a local-first execution engine, and AI-driven automation into a single workspace. Each browser profile operates in full isolation with per-profile cookies, local storage, and configurable fingerprint parameters covering Canvas, WebGL, fonts, time zone, language, and resolution. Proxy IP binding supports HTTP, HTTPS, and SOCKS5 protocols per environment. A unified workspace consolidates environment management, automation agents, data, and team collaboration without requiring separate tooling.

The platform targets business teams managing batch accounts across cross-border e-commerce, advertising and media buying, social media operations, affiliate marketing, traffic arbitrage, and data research. An AI Agent execution engine converts natural language and voice input into browser actions, reducing dependence on fixed RPA scripts. The Skills workflow system encapsulates mature standard operating procedures into reusable, team-callable workflows. MCP integration connects AI workflows with external tools and data sources. Headless automation supports batch inspections, scheduled tasks, and background processes, while CDP access enables both manual operations and automated tool integration.

Team permission controls, operation log auditing, and full execution history support multi-person collaboration across multiple platforms, brands, regions, and member accounts simultaneously. All execution logs, exception statuses, and task results are retained in a single traceable audit trail. Local-first execution keeps account assets and key business processes on-device, providing direct transparency and operational control. Web4 Browser is available in Free, Professional, and Team plans to accommodate individual users through large multi-member teams.
