What it solves

Ego lite is a browser designed for humans and AI agents to operate in parallel. It eliminates the friction of browser automation by allowing agents to run tasks in isolated "Spaces" without interfering with the user's active tabs, while ensuring agents have seamless access to the user's existing logins, cookies, and bookmarks via Chrome data migration.

How it works

Instead of acting as a library that drives an external browser, ego lite is its own browser. It provides a connection layer called ego-browser that allows any agent CLI (such as Claude Code or Cursor) to control it. The agent interacts with the browser by writing JavaScript snippets that call built-in tools like snapshot, fill, click, and navigate. This code-based approach allows agents to compose multi-step tasks into a single output, reducing the number of tool calls and token usage compared to traditional CLI-based automation.

Who it’s for

Developers and AI agent users who want to automate complex web tasks using their existing agent CLIs without losing their session data or interrupting their own browsing experience.

Highlights

• Parallel Workspaces: Each agent or task runs in its own isolated Space, allowing multiple agents to multitask simultaneously without colliding.
• Code-Based Execution: Agents call JavaScript functions directly, which the project claims results in tasks finishing up to 2.5x faster with fewer tokens.
• Session Inheritance: Supports migrating Chrome data so agents inherit the user's real logins and extensions.
• High-Quality Snapshots: Uses kernel-level customization to produce precise page snapshots, specifically handling complex elements like nested iframes.
• Agent Agnostic: Can be driven by any agent CLI through the ego-browser skill.
