Ego Lite: Browser Automation for AI Agents

Agent-Ready Browser Architecture

Ego Lite functions as a standard Chromium browser that migrates your existing Chrome data, including cookies, login sessions, and extensions. This allows AI agents to perform tasks within your authenticated environment rather than starting from a blank, unauthenticated profile. The browser introduces a "space" system, which creates a parallel, isolated workspace for agents. This prevents agents from stealing focus or opening random tabs in your primary browsing session, allowing you to monitor agent activity in real-time via a dedicated space panel.

Code-Based Browser Interaction

Unlike traditional automation tools that rely on sequential CLI commands (e.g., click, wait, screenshot), Ego Lite uses the ego-browser interface to expose browser capabilities as JavaScript functions. This allows agents to compose complex, multi-step workflows as code, significantly reducing the number of tool calls and token usage. The browser includes a custom snapshot system that compresses web pages into a semantic view. This view assigns short references (e.g., @E1, @E2) to interactive elements, enabling agents to interact with complex UI components like iframes, shadow DOMs, and dynamic widgets without relying on fragile CSS selectors.

Practical Application and Limitations

Ego Lite is designed for developers and power users who need to verify staging environments, perform QA testing, or automate tasks on websites lacking robust APIs, such as LinkedIn or CRM dashboards. While the browser is currently free and macOS-exclusive, it is not an autonomous agent itself. Users must connect external agents like Claude Code, Codex, or Cursor to the ego-browser layer. Users should remain cautious regarding data privacy, as the content of the pages the agent interacts with is still transmitted to the underlying model provider.
