The Fastest Browser for AI Agents to Run Web Automation

Jev Browser is a browser where you and your AI agents work in parallel. Agents run tasks in their own Spaces—isolated workspaces inside the same browser—while you keep browsing in yours. No hijacked tabs, no mouse stealing, and up to 2.5× faster execution on fewer tokens.

Parallel Isolation Architecture

Your Agents Multitask in Isolated Spaces

You browse up front. Your AI agents work in the background. They never collide, steal focus, or touch your mouse.

Engineered from the Ground Up for Agents

Traditional browser automations are clunky bridges. Jev Browser is the native platform built for modern LLMs.

Code-Based, Not CLI-Based

Capabilities are exposed as in-page JavaScript functions that agents execute directly. Instead of slow back-and-forth loops (call tool → wait → inspect), your agent writes expressive code that solves multi-step workflows in a single pass with dramatically fewer token roundtrips.

🛡️

Dedicated Space per Agent

Each agent receives its own isolated sandboxed Space. Live monitoring allows you to observe progress, inspect cookies, or pause and take over whenever you desire.

🎯

Strongest Page Snapshot

Custom AST compilation extracts clean interactive elements tagged with concise @ref markers. Recursively handles deep shadow roots and complex iframes where other tools fail.

🔑

1-Click Chrome Data Migration

Inherits cookies, logins, bookmarks, and sessions without credential sharing. Your agent can immediately navigate authenticated dashboards safely.

🧠

Jev Experience Accumulation

Jev decision intelligence compiles verified action paths into reusable probabilistic routes, accelerating subsequent runs on identical domains by up to 5×.
