ego lite: A Chromium Browser Built for AI Agents
ego lite：为 AI 代理打造的 Chromium 浏览器 ⭐️ 8.0/10

Citro Labs released ego lite, a Chromium-based desktop browser that lets AI agents (e.g., Claude Code, Codex, Cursor) run web automation tasks in isolated Spaces, with zero configuration and local data storage. The browser also serves as a daily-use browser for humans, seamlessly integrating agent capabilities via the ego-browser skill. ego lite introduces a new paradigm for human-agent collaboration on the web, enabling multiple agents to work in parallel without interfering with the user's tabs or login states. This could significantly reduce token costs and task completion time for complex web automation, addressing key pain points like CAPTCHA handling and session inheritance. Agents operate in isolated Spaces, each inheriting the user's login state, with handoff mechanisms for CAPTCHAs and 2FA. The browser uses code-based execution via JavaScript functions (Playwright-style) rather than CLI commands, claiming 3.45x speedup over Vercel agent-browser, and semantic snapshots are built into the Chromium kernel for reliable cross-domain iframe and Shadow DOM handling.

rss · meng shao(@shao__meng) · Jul 25, 10:27

Background: AI agents often struggle with web automation due to issues like maintaining login sessions, handling CAPTCHAs, and interacting with complex web components like Shadow DOM.
